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.

    • Best value and quality I’ve ever bought!
Size: Queen Style: 14" Pattern Name: SmartBase® Only
I’ve bought other frames before for more money and even had wood slates, that didn’t hold up as good as this one. I did a lot of research this go around, and found this one on many lists as a quiet and durable bed frame-which was a concern for me. Have had it for 4 months now and zero sound or squeak when getting in or out or moving around. I bought the heavy duty even though at 145lbs I could have saved a little and bought the regular. What I was most surprised at first glance was how thin the frame looked out of the box and how lightweight it was. I thought I had made a mistake with this one, but I was proven wrong. It’s incredibly sturdy. The matress does not move around. The frame stays in place but can be moved without a lot of pressure if I need to clean underneath. It was so easy to put together, also. Literally snaps into place and a few screws tightened. Took about 10min or less. I love that there is storage space under my bed now also. A really great quality purchase. ... show more

    • TWIN XL - Top Quality at a good price
Size: Twin XL Style: 14" Pattern Name: SmartBase® Only
I was looking for a sturdy, easy to put together bed - this is both! The overhang is great, so no one bangs their toes on the legs of the bed and there's enough room underneath for storage. Highly recommend the Twin Xl.

    • 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

    • Deserves 10 star
Size: Full Style: 16" Pattern Name: SmartBase® Only
Amazing product. Set up took less than 5 min, and that's with un boxing it, and cleaning up. Easy set up. No assembly required. So far, it is extremely stable. No squeaking, shifting, etc. 16" drop has 15" of space underneath. Metal legs are set in a few inches to provide space so your toes don't hit it. Rubber caps on the bottom of legs. I did order mattress guards so the mattress doesn't shift for $10. Also ordered something like a bunkie board except there's no slats. It's compressed cardboard, super strong. It will support your mattress properly, it was under $60. Everything has worked out great!!! I originally ordered a 20" different metal frame. Took over an hour to set up and was way too tall. Looked awful. I needed the underneath storage but realized the taller the bed, the more unstable it will be in the future. This 15" underneath area ended up being perfect. Love love love this... ... show more

    • Sturdy
Size: Full Style: 18" Pattern Name: SmartBase® Only
This frame is super simple to put together and is very sturdy. I did four stars only because the mattress does slide a little bit on it and I have to adjust it every night to get it back into place. My mattress is not really heavy but it didn’t move on my other frame, which was a completely different type. I’d say it moves about an inch or two. Not a big deal to adjust. ... show more
