I think this "foundation" caused my mattress to get a dip. So upset. So must lost money. From an AI Q&A: Q: Proper mattress foundation gap size. A: A mattress foundation gap size should be no more than 2.75 inches apart, especially for memory foam mattresses, to prevent sagging and ensure adequate support.

Comes as 2 twin beds. 2 screws/bolts to connect the 2 together as a queen size. Super simple! Definitely worth the money! Holds up well, and I am a “plus size” woman! I would suggest to oil it with WD40 as it will screak a bit. Other than that, I absolutely love it!

I brought this frame three weeks ago and I just open it to weeks later to put it down for a new mattress and the box came kind of wrap at the top and when I open up the box it was a dent in one of the rails and then the other long rails came kind of bent up as well it had a lot of great reviews on this rail but the packaging was horrible and it’s kind of suck because one of the bars is bent up in a couple of the long ones is bend as well It’s not even worth one star but I had to put one star to order to send it through

When I bought a memory foam mattress to replace our regular king-sized mattress some years ago -- the cost was enough that I cheaped out and used our old frame and split box spring rather than a platform type recommended. It seemed to be "fine" -- and truthfully, it's such a pain to move everything that I just kept it despite the fact that the box spring would sometimes spread/split, the old frame (which can adjust from full to king) design is horrendous and weak, the legs would stub toes at the corners, the ends could impale your shin, the casters would sometimes come off, and the space underneath is practically useless and nearly impossible to vacuum. Eventually, what was "fine" really wasn't. Regular box springs really don't provide the correct support for memory foam-type mattresses -- and it began to show. Worse, the frame was decidedly evil: one shouldn't have to put blocks of wood under the legs when casters fail, pool noodles around sharp parts, or roll to one side when it suddenly splits. Enter this frame: I found this and finally decided to bite the bullet. I have to admit, I dreaded its arrival as much as looked forward to it. I imagined the removal of the box springs, disassembling the old frame, putting this together and I am pretty lazy. Frankly, I didn't even know if I would be able to carry this into the house -- let alone up the stairs into the bedroom. I decided to put off worry about it since it had a 2-week estimated delivery time -- but it came much faster; in less than a full week from placing the order via Fed Ex. The box is packed very well -- it's a large square and weighs about 50 pounds. I could lift it myself -- however, because my arm span in short (I am 5'4), it was very awkward because it is difficult to get a good hold. My Zoomer son had absolutely no issues and easily carried it alone up two flights of stairs while making fun of me for being short. That earned him the privilege of carrying out the old box springs. :-) Two able-bodied short humans could easily carry this, or one able-bodied taller Zoomer alone while giving snarky retorts. All but the tightest of places should have no problems with maneuvering it. Assembling it took 10 minutes, and the majority of that time was spent disposing of the packing materials and listening to my skeptical Zoomer question how a metal frame would be more comfortable than a padded box spring. Once it was together and the mattress was on, we both laid on it to test it out -- and it was amazing. Not only was the difference in comfort astounding -- he admitted that he was wrong -- which we now call "The Miracle of the SmartBase Platform Bed" and made it a yearly holiday. It is a perfect height. It is wonderful to be able to store things and clean under it. I was worried I would need to buy the separate piece sold by this company to attach it to my surrounding headboard (it stands alone as it has two wardrobes attached) -- but this is so sturdy and solid that I don't need it. After several nights, it is indescribable the difference made in the comfort level. In fact, my bed is so comfortable, it even lured the very same Zoomer away from gaming to lay on the bed to watch some TV with me. This is the "Second Miracle of the SmartBase Platform Bed" I would recommend this base to anyone.

I received this smart base with a Zinus mattress. We noticed a definite sag in the mattress and a very definite high spot in the middle lengthwise. I am not small, 6'2" and 240 lbs. When we took this mattress and base down, I placed mattress on hard floor. Mattress had some sag and high spot in middle, but definitely not we were feeling when it was set up. I checked the smart base with a straight edge. It has about 3/8" of sag from side to side in areas under body and that caused the high spot up and down the mattress when set up. Like that the mattress has held up so well, but disappointed in the smart base. May try putting a 1/2" piece of plywood on top of base to spread load. Mattress was the 13.5" sping and foam version. Would probably buy again, but will definitely strengthen the base.

very easy set up, did what it’s supposed to.

Sturdy. Easy to put together. Nice space underneath for storage.

Very good quality and easy to assemble.

Easy to put together and very secure for my new memory foam mattress. I wish my headboard had fit the little holes on the end but I did have to purchase a connector set separate. I would gladly recommend or buy another in the future.
