We got this Zinus 8" frame to support the layered alternative to a conventional mattress we got for our 1940s twin bed. Our layered alternative is a new 4" traditional (all cotton) futon topped with two pieces of foam (1" high density, 2" memory) and a thick cotton mattress pad. The mattress ended up higher off the floor than we expected (a short person's feet sort of dangle). Even with frequent turning, if this futon is used regularly it'll compact some, so the 8" will work alright. But if we add another bed like this, we will probably get the lower profile 4" frame. Delivered in about a week, the frame was well packaged and not as heavy as we feared. A middle aged woman carried it in easily. It came with instructional diagrams (no text, so it's universal, language wise) – not that we needed them. The assembly steps are obvious. It went together quickly and easily. The frame's wood is straight, clean, and smooth with no obvious flaws. Presumably the original plan was for buyers to attach the four support pieces to each other using the included screws. Instead, two of the corners came pre-connected with hinges. Though this made assembly a wee bit faster, we would have preferred the screw method because the (low end, sort of flimsy feeling) hinges are on the loose side. Truthfully, this is probably irrelevant because once in place, the frame isn't going anywhere. One note of caution though: make sure to support the hinged pieces along their full length so that one (probably the short side) doesn't flop down and stress the hinge. Otherwise the hinge could twist or break and you'll be drilling your own hole and reaching for one of the extra screws that is included. The slats, for the twin size anyway, come in two sections. The slats in each section are connected together with a flexible fabric tape (if I'm remembering right). Once the sections are unfurled, small pieces of Velcro on the bottom attach to corresponding Velcro pieces on the top the frame itself (the sides pieces that are now connected). The slat sections went into place easily (with only minor effort required to match up the Velcro) and seem perfectly sturdy. Instead of installing the cover, we opted to "dress" the frame with a spare fitted sheet made of microfleece for now. We thought the pressed (not woven) fabric/papery material that forms the cover's sides (similar to what most reusable, biodegradable shopping bags are made of) might prove too tempting for our cats' claws. Now we wonder not only if the wood itself might be even MORE tempting, but also if the cats may decide to climb up through the frame's openings and perch tree-limb style on the bed's original slats, which we left in place (probably unnecessarily, as it turns out). This likely won't hurt the cats OR the frame, but it could present a problem on vet visiting day! So, the assembled box frame is sturdy and fits perfectly where the bed's slats normally go. Guests have reported sleeping comfortably on it, and test naps have been successful. Even though this product had ZERO Amazon feedback when we ordered it, we chose to go with the Zinus version instead of the other – heavily reviewed – manufacturer's version because it cost a little less and looked like it was made at LEAST as well. And we like supporting new vendors if we can. We highly recommend this to anyone who, like us, has opted out of expensive, often unsatisfactory mattress/box spring sets.

This was exactly as described in the listing. I have the queen-size, 4 in. There have been questions about the number of slats, the space between slats, the method of fastening of the slats, and whether there is a center lengthwise support. I don't recall for sure, but I'm going to say there are 12-13 slats forming the top surface with 2.5 - 3 inches between them. They support a memory foam mattress well, and with the cover on the foundation, there is no sag of the foam between the slats at all. I also will support a conventional mattress well. As mentioned in some reviews, the assembly instructions consists of 4 pictures with NO text whatsoever. That is probably more than necessary, as the assembly is pretty obvious; but it would have been nice to have some markings on the pieces or notes in the instructions to provide reassurance that it is being done correctly. Yes, the cover is EXTREMELY tight and difficult for one person to get it pulled into position to zip it easily, but it can be done. Since it comes disassembled, it can be maneuvered up stairs and around corners easily; but WARNING if that is your primary reason for choosing this, the cover comes with a notice on it that it cannot be removed, and that may be true. I didn't try to take it off after I finally got it completely zipped, but that would be necessary if your intention was to disassemble it to move it out in the future. Back to the slats - they come with two sets of half the total fastened on to another by a heavy Velcro tape. One set has a small hole drilled on each end of one slat to fit into a dowel that is in place on the side rails. Then the Velcro hooks onto a matching strip that is fastened to the top of the side rails. This is all the fastening there is for the slats (no screws, etc.), but it secures them sufficiently once the cover is in place. There were questions about noisiness - the foundation once assembled produces no noise and is strong enough to support a couple of 200 lb adults with no concerns. On our bed, this foundation is resting on 4 normal bed slats (that each have a center floor support leg) that are on a ledge of the bed side rails. There is some noise getting into or out of the bed, but not much; and this would be true of any foundation or box spring. Yes, on the queen-size there is a center lengthwise rail that provides support for the middle of the slats so there is no center of the bed sagging even with a total foam mattress. Others have mentioned their surprise at the quality of the supplied Allen wrench and small ratchet. Yes, they are good quality and definitely up to the assembly task. The 2 spare assembly bolts provided were reassuring. I hope this helps you decide. I'm pleased with mine.

I like this as it’s not as high as other box spring designs, thus it makes it easier to get in and out of bed. Very good quality construction and easy to assemble. Quiet as well- it makes no sound when using the mattress.

This platform was super easy to assemble. However after reading some reviews of them breaking I could see why - the wood is pretty lightweight and is built with lightweight hardware. I ran a 2x4 down the center lengthwise (2x4 fit perfectly, just had to cut to length and drill a hole in end pieces and secure with 3” screws at each end). The slats sat perfectly on the 2x4. I also put small pieces of 2x4 (approximately 2” in length) in all 12 spaces around the sides. I had a twin so bigger sizes may have more spaces. Thing is solid as a rock now.
