Description

The Heavy Duty SmartBase is a mattress foundation even stronger than your Monday morning coffee. Engineered precisely with heavy duty steel and unwavering support from multiple points of contact with the floor, this frame is built tough enough to support up to 3000 lbs of evenly distributed weight. With a frame this sturdy, you can bet that your mattress will be optimally supported for the long haul with absolutely no sagging. Its metal platform effortlessly supports your foam, spring or latex mattress without the need for a box spring. Built with valuable underbed space for extra storage, this handy frame also includes practical features like recessed legs and plastic caps to protect your floors. And although the last thing you’d expect from a frame this tough and functional is tool-free assembly, that (and a 5-year worry-free warranty, no less) is exactly what it comes with. Easily unfold the base, extend the legs, use the easy locking system to secure everything in place and voila! You’ve got a substantial mattress frame in less time than it takes to brew that pot of coffee.

    • Better than expected
Size: California King Style: 18" Pattern Name: SmartBase® Only
Lightweight but so sturdy and quiet. Easy to assemble. Great room for storage underneath.

    • Updated: Full review two years later! (Preliminary Review: Unboxing and set-up)
Size: Full Style: 16" Pattern Name: SmartBase® Only
I will write a full review of this bed frame after I have used it for a while but wanted to give a preliminary review first. I've had it for about a month before setting it up (waiting to get a new mattress and get rid of my futon), so it's been in the box which was on the large side but was able to tuck it away in my kitchen for a few weeks. I live on the third floor of an apartment building and while the box was a bit bulky and heavy, I was able to get it up to my apartment by myself with no problem. I'm a big girl with a not-so-great back, but it was definitely manageable. Having forgotten anything I read in the reviews about assembly, I was expecting a cumbersome set-up job with a lot of little parts and pieces and metal clanging around as I jostled this frame around my tiny little one-room apartment. I was pleasantly surprised to find that the frame consists of two separate pieces that fold out, and are then joined together by two screws in the middle. THAT IS IT!! Putting it all together took me about 20 minutes. Probably would have been less if I had more room and wasn't having to rearrange other furniture almost every step of the way. I have my new mattress set-up on the frame and expanding now (I got a Tuft and Needle original mattress which is a little longer than the frame, so not sure if that's a frame issue or mattress issue, but hardly noticeable) and was impressed with how easy it was to move the frame during the unboxing of the mattress and how lightweight it is. I am honestly a little apprehensive about the two pieces of the frame staying together with two screws as the butterfly bolts don't screw as tightly as I would like. I anticipate maybe having to find a washer or nut or something else to just make sure the fastener doesn't come off, but that's super easy so I'm not too worried about it. I did really appreciate that the hardware (two long screws and two butterfly bolts) came in a package together so it was easy to set them aside and not have to worry about them flying around. Oh! I also really appreciate that the frame came with two non-slip pads that are often used for carpets. That will hopefully help prevent the mattress from slipping off the frame. The storage capacity underneath this frame is AMAZING! Because there are two braces in the middle of each section, the storage underneath is in two sections divided horizontally but I can fit so much stuff under just one section because of the height which I am loving in my small apartment. The stuff from under my futon is now under ONE section of this frame, leaving me so much more room to store things that have been getting in the way. I will give it a full review after sleeping on it for about a week, but I'm optimistic that I will be highly satisfied! ****UPDATED REVIEW**** Two years later I am back to finally update this review! And two years later I am still 100% satisfied with this bed frame! When I moved last summer (Aug. 2020), taking this apart on moving day was a snap and it took me five minutes to set it up at my new place. I had previously been worried about the two screws joining the sections coming loose but that has been a non-issue in the last two years. I eventually added a bed skirt to help conceal the totes and things I have underneath, but the storage space has been such a game-changer for me, even when I moved to a bigger apartment. The frame is super quiet and holds up with some company in the bed, so no complaints there! ; ) I really cannot recommend this frame enough, it is one of the best Amazon purchases I have made. If you're looking for something sturdy, easy to put together (seriously only like FOUR PIECES in total!), excellent under-bed storage, and durable, GET THIS FRAME! ... show more

    • Sturdy and easy to set up.
Size: Twin Style: 18" Pattern Name: SmartBase® Only
This is very sturdy. I have a10” mattress on top of it. There was no assembly. I use it in my camper van so I needed something that was easy to put in sand take out when I wasn’t camping. The legs fold in to make it easy to carry and store. The only minor issue I had was that my mattress slid on it because there are no sides. I solved this by purchasing things that slide on to the frame and are raised up to hold the mattress in place. There were six in the set. I highly recommend this bed frame. ... show more

    • Beware of the Height & Tall Mattresses!
Size: Queen Style: 18" Pattern Name: SmartBase® Only
I bought this frame along with a Zinus 12" Queen mattress and egads does it sit awfully high. I had no idea how high it would set and shame on me for NOT sitting and calculating this out ahead of time because the numbers are right there before I bought it. I also could easily have gotten out my tape measure and done some checking but I was in a hurry to get a new mattress so I could actually SLEEP as my old mattress & box springs were kaput. It's extremely sturdy and simple to set up - even a blind person could set this up because all you have to do is pull it out of the box, pull the legs up and twist the nuts into place and you are finished. It holds a tremendous amount of weight so a whole family could sleep on it or a couple who are 'extremely' large with no fear of it failing. I am going to re-order a new one but this time get the shorter one closer to the floor to use with my Zinus mattress and put this one in the guest room with a regular mattress on it. There is a remarkable amount of storage space under it so if you need space to store your stuff in your room from luggage to whatever may be, this is ideal for it to make use of that dead space. It is also fairly light enough that an average person should be able to move it around with a Queen mattress on it if they go slow and use their legs. Other than its extreme height as mentioned previously, I'm also not a fan of the protruding metal pieces that bang into my leg in the middle of the night when I have to get up to go pee. That is my only other complaint and yes I have smacked my poor legs on both of the protruding ends but I have all but tied pillows over them. Zinus engineers, ease up on the excess metal as it is unnecessary and painful! ... show more
