Moving into our new condo, we discovered that our queen box spring would not fit down the stairs to our bedroom. Having other nightmares to deal with as far as the new place went, replacing it with a split queen was stuffed into the backs of our minds. For a moment, my bf and I thought it was fun to slum it like we were in college again. For a time, of course, until our backs reminded us that we are a bit removed from those years. I needed something to sate us until we got around to buying a new box spring and chose this foundation based upon the reviews and the price. The general consensus is that it looks super cheap and that most who own it are surprised by its durability. Add me to that party. I carried it down the stairs with no problem and assembled it with even less of a problem. I am more handy than many and I assembled it in what probably amounted to an entire 90 seconds (if that), which is to say that anyone could probably give it a hard enough look and it would assemble itself well. It was really that easy. If you can flip your wrist, it can be done. After the assembly, I flipped my mattress onto it and dressed the bed. Still skeptical, I gave it a good kindergartener-intensity jump. You know, for quality control purposes. When my bf arrived home from work, he was also pleasantly surprised. I am a woman of average vertical measurement and perhaps slightly below average weight (on a good day) and my bf is tall, but of average mass. The foundation has stood up well to various activities, and I haven't even had the need to tighten up the wingnuts (which will inevitably have to happen). At this point, I really see no need to replace it with a real split box spring. I am a fan. An addendum: I write this a year and a half later, and am still pleased with its performance. This has since weathered a disassembly and reassembly in a move from the old place. Not only is it still incredibly well intact, but I have yet to hear a single peep from the frame. Not one. Our last (ridiculously expensive proprietary) frame was awful and being surreptitious about anything that may happen on a bed (like who doesn't jump on the bed and eat gummy bears?) was not happening. This thing is a ninja. I still love this frame.

First, a little note. When people review stuff online, it's usually because they totally loved the product or hated it. Unfortunately, that doesn't account for STUPIDITY, so reviews should be treated with caution. Personally, my favorite reviews are usually 3 stars. They're usually pretty honest. Here's how I use online reviews: a) I carefully read the full item description, features, and specs from the manufacturer, and look at photos of the product to check for consistency. b) I read five to ten of the 5-star reviews to see if what the reviewers enjoyed matched the item description. c) I read every 1-star review and use a rubric that scores on: i) the reviewer's intelligence level (not even highest education received and I feel like I'm very generous on spelling and grammar mistakes, as I think an average fourth grader is still competent enough to rate most products), ii) the reviewer's experience level with products of that nature (for example, if I'm buying carabiners and the reviewer says they know nothing about climbing, then I know I can't trust the review), iii) whether the reviewer is reviewing the product or the seller (yes, there is a different place to rate the seller, as well as the packaging and shipping speed, but some people don't seem to understand that, see above for stupidity), iv) whether the reviewer read the item description, v) and finally, what they were actually disappointed about. This bed is exactly as described. I bought it to replace a platform bed with wooden slats that I didn't feel confident would stand up again after another move and my career field leads to lots of relocations. Field technicians in biology, ecology, forestry, etc. have adopted the phrase "bio gypsy" and for good reason. I read multiple reviews for this product and loads of other beds like it before I decided to take the leap. And leap I did! 1) It is extremely easy to setup. I took about 20 minutes, diligently checking that I'd securely tightened all the foot-supporting bars' wing nuts: first when the two halves were upside down, then when they were right-side up and finally after I'd connected them. There were instructions for assembly, but only a very very dumb monkey would need them. The support bars for the legs are very obvious and if they aren't, try to imagine any reason for the wing nuts, to which the support bars attach, to exist on such a minimal design. Also, part of those 20 minutes were also spent making sure the thing would disassemble as easily as it setup. It passed that test. 2) I've had the bed for less than a week, but I've been testing it pretty thoroughly (though not in the "active couple" way quite yet, that will be next week (; ) by jumping up and down and rolling and bouncing. I've tried to make it squeak. I weigh ~140 lbs (which isn't particularly heavy, I know, which is why I've been aggressively jumping to try to get a squeak) and I can't get a peep from this thing. There are no pieces of metal to rub together to make any god-awful noise. There are some reviews that mentioned both creaking AND squeaking. I may be wrong, but I consider those to be very different. Creaking would occur if there was some part of the frame rubbing another and squeaking is when a joint or contact point moves audibly. There is absolutely no creaking here. Oh, but wait, I should mention that I took about two minutes to adhere a small piece of cardboard (cut from the box) to each of the twelve feet to keep the rubber feet from squeaking on the hardwood floor. I would've done that anyway to protect the floor. Also, I placed some to act as bumpers on the parts of the frame that could contact the walls during grown-up activities. A little bit of foresight should go a long way there, I think. If the bed starts creaking after a few months, you should check that all the nuts are still tight. It is normal for those things to loosen up. 3) This frame is not an eyesore. If it doesn't look like a fancy bed for your master bedroom, then buy a bedskirt. It does look metal. And it has lots of under-the-bed storage space. That matches the item description and the photos. 4) There are no brackets for head- or footboard attachment. Those are sold separately. 5) My mattress doesn't slide around. I'm not sure why that's an issue for other people, and there aren't any rails or listen lips to keep it in place, but it's still not an issue. 6) This product eliminates the need for a box spring. Some reviewers have said they feel like the princess and the pea because the mattress is so high when they use this frame plus a box spring. Also, there is no need to buy pieces of particle board to add extra support for the mattress (unless it is a foam mattress with absolutely no support for itself). The thin metal wires are strong enough for the job. 7) I expect the frame to be compatible with some wooden frames (probably if made by the same company), so I'm not surprised that some people couldn't get this to work out. Check the dimensions of the wooden frame you want to place this inside of and check the product specs before ordering.

We’ve purchased several of these mattress foundations over the years, and they’ve consistently exceeded expectations. The assembly is straightforward with no complicated tools or instructions and the design is intuitive enough that one person can set it up without hassle. The structure feels solid and stable once assembled, with no squeaks or creaks, even after months of use. My favorite part is the generous under-bed clearance, which makes storing bins, seasonal clothes, or extra bedding effortless. It’s rare to find a platform that balances sturdiness with maximum storage so well. Durability is another highlight. Each frame has held up beautifully over time, showing no signs of sagging or warping. For anyone looking to replace a box spring or maximize bedroom storage without sacrificing stability, this is an easy recommendation. Reliable, practical, and quietly effective. Once the mattress is on top, great stability and sleep quality follow!

The title says it all. I purchased the frame on June 27, 2013. Notice the date of the review. The frame is rated a whopping 2400lbs. Maybe that's 1200lbs for each of the smaller twin frames that make up the queen. It was easy to assemble with no tools. The design is really good. But today, I sat on the side of my bed for a little while - maybe 10-15 minutes - and felt something "give". I came home from work to check it out, and noticed that a section of the frame - where I had been sitting up - noticeably bent. REALLY BENT. I was shocked. I know that even with steel you can get weak spots. And I'm a big guy whose had no problem sleeping on TWIN size beds most of my life without incident. This is just shoddy construction. I decided to exchange the frame - only because the design is so easy to assemble - so this review will be followed up by an update once I get the new one, and return this one. I hope my review improves. UPDATE: I received my replacement frame just days after I wrote the previous 1 star review. Here is my setup: Sleep Master frame, Queen Size 8" Memory Foam Mattress, and two (2) 30" x 80" 11/32" plywood boards (one for each of the two frame platforms). I went to my local HomeDepot and got the plywood boards,and had them cut to the exact measurements of the bed. The 11/32 size is very thin, but still strong enough to serve its purpose, which was to distribute weight across the ENTIRE frame. People have been complaining about the squeakiness of the frame, but weight distribution ELIMINATES nearly all the squeak. The Memory Foam mattress takes care of the rest. My platform bed has virtually no squeak and feels Super-Solid. I strongly recommend getting some kind of thin board across the platforms. Without it, this frame has tiny pressure points at each and every metal cross wire, which can also individually bow and/or bend. So I recommend this frame if you want an affordable platform bed, that gives you storage space beneath it. Add yourself a decent headboard and skirts, and you will have a very attractive, modern looking bed for a fraction of the cost.

A retired Marine gunnery sergeant now at 285 lbs. 69 yrs young and as we say in the Corps :no longer lean but still mean, semper fi. I bought a town house 5 yrs back and as a golfer lower backs are common so I bought a platform bed so I would be lower to the floor when getting up which I felt would take stress off my back. Well last week the bed collapsed, which was made entirely with particle board and cheaply made and was cricking all the time. So I decided to get a metal bed frame that would hold my fat ass and not crick. I'm a guy that researches everything to the 9nth degree whether it be a new vehicle or a loaf of bread. I found the "Zinus 14 inch Smart Mattress" and read that it would hold some 1200pounds! So I, as usual read a ton of reviews. If their claim is correct then it should hold my fat ass up so I ordered one. So here's my closing. It actually arrived super quick, I live in San Diego, California. The majority of reviews I read were mainly about how log it took to assemble and some parts were not included. The parts are simply wing nuts and a couple bolts. I took the reviews as a challenge so I took a quick glance at the instructional diagram and assembled the whole unit in twenty minutes. I would suggest, which I did, is to get four (that's all you need) 1/4 inch lock washers to enhance the security of the wing nuts. So once assembled I said to myself once I put my mattress on it I said to myself" Gunny go for it" so I took a big diver upon it and it was like Heaven! it held my fat ass and my old wavy mattress felt great as well also. However, I AM purchasing a new mid-firm mattress to go with this gem of a Zenus Smart Base. Nothing more to say, the product is exceptional, worth every cent, don't sell it short, it is a must have, LOVE MINE!!

*disclaimer* I live in an apartment, if you do too, you've found the right review! Lemme start by saying, my S.O. and I had our mattress on the floor for the first 3 weeks of moving in to our new place. This meant our brand new sheets, comforter, and a few throw pillows, often frequented the floor; they all picked up dust, dirt, cat hair, etc., the usual day to day messes of life. Stepped on, slipped on, you name it, it probably happened. If you're in this boat, you know, it can be a little frustrating. I told myself I'd build a box spring, buy a nice bedframe with a headboard, do this right... That was 2.5 weeks after telling myself it would be worth it, looking in local shops for pre built box springs and seeing them for no less than $100, and almost $200 after delivery + taxes. Well, since I'm here I guess you can imagine how that went. With work, trying to make the apartment feel like home, constantly cleaning and trying to maintain a social life, and without really your own front yard to do the whole building thing, the idea just became a faint whisper. It was around this time I also noticed the closets were a bit cluttered too, but I just told myself, "this was apartment living" One night, I decided to come to amazon to see if they sell box springs. To my absolute distrust and hesitation, I clicked through some reviews of this platform bedframe. It seemed pretty promising, but some reviews had a couple issues with broken parts and said it felt uncomfortable. I decided to roll the Amazon dice and purchase the platform bedframe. 3 days rolled by and it came, shipped to my apartment and dropped off with a loud "thud" on the front door. The package was heavy and I guess the delivery guy was frustrated from my place being such a frequent stop for him with heavy packages. "Great..." I said, hoping no damage had occurred. The box was pretty beat up too. I opened it, assembled it (took about 5 minutes of finger tightening wing nuts btw) and plopped the mattress up on it. Thankfully it seemed to survive it's rough journey from the warehouse to my place, I noticed two things immediately: 1.) This was the answer to making the bedroom feel more like a home 2.) There is a ridiculous amount of storage underneath the bed that simply isn't allowed for in closets. I stuffed as many rarely-used items under the bed as I possibly could, which allowed me to straighten up the closets. I even made room to keep the box to the frame in there, just in case the S.O. didn't like it and we had to send it back. She came home and also instantly appreciated the look and feel of the bedroom. Needless to say, we did some investigation to see just how loud and sturdy the bedframe is. It's silent, and unmoving! ;) I threw the box out after 2 nights of sleeping on the bed, confident in my purchase and ready to guide other potential customers with a humongous review on why they should also take the plunge and try it. It seriously is the perfect bedframe for an apartment. You'll be glad you tried it!

I am a fairly big guy. I have had plenty of bed frames that have broken due to both carelessness on my part as well as the bed frames not being strong enough to hold my weight. We have done everything from rigging the bed frames and without fail they always ended up breaking. So for almost 10+ years I have been sleeping with a mattress on the floor. I started to do research on bed frames that would be able to hold together with my weight and I came pass this Sleep Master SmartBase Mattress Bed Frame which I saw could hold up to a advertised 2,400 pounds and I was automatically sold. The reviews of this bed frame were very good, the price was reasonable, and that is when I made my purchase. I got this bed frame and once unboxing it I was very skeptical. I could not believe that these two separate frames with two nuts and screws to combine them together to create a full frame would hold someone of my size, especially separately. The legs seem to thin, but the only thing that looked promising was this was made out of steel. Even screwing them together I still was very unsure. I was even weary about climbing onto this bed frame thinking it would collapse under my weight. Once I put my mattress on it and made my bed up I finally garnered up enough courage and climbed on and I was amazed it did not fall straight to the floor, matter of fact, it did not squeak, I felt no budge, nothing. This bed frame was a very solid, very sturdy, and very strong. I was amazed. The more I climbed on and off this bed frame my confidence increased and I am sure yours will too overtime. There were a few things I needed to get used to. First off, since I have been relatively sleeping on the ground for a decade I needed to get used to how high I was sleeping in the air. I believe it's about 14 inches off the floor which is pretty elevated. As an adult I can easily fit underneath this bed frame. You can comfortably place luggage and other storage items underneath it just to give you an idea. I have only had this bed frame for about a week so any squeaking that has been a big complaint and con of this bed frame has yet to occur. One accident I made while purchasing this product was buying a box spring. You can buy a box spring for this, but I would highly suggest you save your money and DO NOT BUY A BOX SPRING. With how high this bed frame sits off the ground and your mattress on top of it, with a box spring, you will be able to outstretch your arm and touch the ceiling on your knees with ease. Just my suggestion. This bed frame and a mattress is perfectly fine. I just want to touch on how simple this bed frame was putting together. You need no tools. You simply just latch and screw on tightly with your hands. It is that easy. I am pretty sure anyone from a child to a elderly person can put this together. Overall, I am impressed with this bed frame. I have no complaints about it. Easy to put together, it's a strong, sturdy, and solid bed frame that you can have confidence getting in and out of. If you like sleeping high then you will definitely get that from this product. I would suggest this to my fellow big people or just anybody who is looking for a new bed frame. I already suggested it to my brother. Right now, I will give this a 5/5 perfect score. I highly recommend this.

This is the first time I got this 14" full sized bed platform for my new full sized mattress because I wanted one without needing to purchase a box spring. I can say that after a couple days I am very pleased and satisfied with what I got. This bed platform was very easy to set up. I did it all by myself with no help. No wasting time trying to put the legs and slats together because this comes in practically two pieces. All I had to do was to follow the instructions and put the screws in for the legs and join the two metal platforms together. It is very stable on my carpet floor and is very sturdy now that I have my mattress and comforter on top. I'm only 5'0" and about 120 lbs so I don't see this platform possibly bending or collapsing from my regular use. Even if I use the bed with a heavier person on there I think it is still very stable. I have not heard any squeaking as I was rolling around and moving on my bed. I also like that they included some nonslip adhesive strips as it helped keep my bed skirt in place while I placed my new mattress on top. I didn't get a headboard so I'm not sure how easy it is to install any headboard outside of the brand. I am currently renting a room in a house and storage space has been pretty limited to me. I was able to fit a lot of things underneath the smartbase, including my shoes, styrofoam cooler, some clothes, bags, and clean containers and food jars. Pretty much any storage container under 13" in height can fit underneath the base. The diagonal bars that hold the legs in place and legs in the middle of the base are in the way, so if you have any wide and tall storage containers then you have to be a little careful. If you need to fit standard storage containers, I would recommend getting the taller smartbase such as the 16" or 18". For someone of my height with a 14" base plus 8” mattress and a 2" mattress topper, I did not have trouble getting on and off of my bed. My feet dangle about 2-3" off the ground now. I could imagine that any smartbase greater than 14" would give my bed a lot of height. Overall I am very happy that I got this base. You can probably tell that the black cat in one of my pictures is very pleased, too. I would argue that even if you don't need much bed storage space, this is a great bedroom essential to have because it is easy for one person to put together, dismantle, and move and you can easily add height to your bed without sacrificing its stability and sturdiness. And with a good bed skirt and comforter, you'll forget that you even have a metal bed platform!
