Description

Believe it or not, we’ve made the box spring more functional, more durable, and dare we even say, fun! Our No Assembly Box Spring is not your average foundation. Its folding design not only makes set-up insanely easy, but it also comes in handy on moving day, maneuvering easily in and around tight hallways and corners. What’s more, it features a structure made of thick and durable steel, meaning that frames and mattresses may come and go, but this box spring will be with you for the long haul. Once unboxed, this brilliant foundation practically assembles itself by taking shape once unfolded. Essentially, deciding where to place the bed will take longer than setting up this box spring. Backed by both our 5-year worry free warranty and hundreds of positive customer reviews, this box spring is about as easy as decisions get.

    • Great for a wood slat frame bed
Size: Full Pattern Name: Box Spring
I bought the Zinus metal box spring, along with a memory foam bed-in-a-box mattress, to replace a traditional mattress and box spring on an old wood-frame full size slat bed. The traditional set was much, much too heavy for the wood frame, and the side rails were starting to warp, the slats falling out frequently. The Zinus has actually stabilized the bed frame so I don't have those issues any more! It's quite rigid, acts more like a platform than a box spring, and works very well as a foundation for the memory foam mattress. The new combination is light enough that I can easily lift it to adjust the slats if they start to slip out of place. Assembly was easy, if a little awkward. I was doing this by myself, in a small room, so it took some maneuvering to get the Zinus out of its box, unfolded, flipped over, and set on the bed frame (when you unfold it out of the box, it ends up bottom up.) Really not difficult at all. I find the new configuration very comfortable; I've slept on it every night for about two months. The Zinus is quite rigid, as I said, but the memory foam mattress has enough "give" in it so I don't notice it. I haven't had any problems with the Zinus squeaking, and I checked after a month or so and didn't see any wires or metal pieces coming out of the cover or damaging my mattress. Absolutely perfect for what I needed. ... show more

    • Light weight and just the right height!
Size: Queen Pattern Name: Box Spring
We bought this to lower our mattress to make it easier to get in and out of bed. It was easy to assemble, light weight yet sturdy and was the perfect height for what we needed!

    • Sturdy, Easy to Use, and Works Great!

Search for my username on YouTube (dugroz) and you can see my review/unboxing of the product. This low-profile foundation does exactly what it says it is supposed to do, and does it very well. It comes in a fairly large box and is a bit heavy, so an elderly or frail person would likely need help. However, once it is unboxed, there is no assembly needed, just unfold it, flip it over, and zip it up. (As others said, if you flip it open in the instinctive way, you need to flip it over.) It would be very easy to take with you in a move. This is not a "Box of Springs" - there are no springs inside. 95% of modern mattresses do not need a true "box spring" anyhow so that's fine. The purpose is just to raise up your mattress. It does not soften the mattress, nor is it designed to. "Foundation" is the better name. The bars are about 1/4 inch thick, and about 3 inches apart. The Foundation (as I measured it) was almost exactly 4 1/4" high (no big deal for me, but just noteworthy if you need "exactly" 4 inches in height). I was a bit Leary about using this with my Hybrid mattress since I was afraid that (because the bottom is foam) it would sink through. However, I emailed the mattress company and they assured me that this foundation is fine to use (I have a Sapira mattress). About 3 weeks of use so far, it's holding up fine, and the mattress works very well with it. Very sturdy, no sagging. No noise, no squeaking. We have a queen and it supports two grown adults just fine (the paperwork that came with it says that the queen size and up can support 2,400 lbs. of weight, which seems a bit ridiculous (2 people plus mattress weighing 2,400 lbs???), but the idea is that it is sturdy. . The sides are a nice patterned white cloth. Nice enough that we have not felt the need to cover it with a sheet like with did with our old one! I would recommend this foundation if 4 inches is the best height for your bed setup. Edit: 05/01/2017 - Still holding up great. ... show more

    • Awesome Foldable Spring Box
Size: Full Pattern Name: Box Spring
Review Image by Cookie Cookie
I am excited, I used the metal box spring as a platform bed, my mattress is 16" and a regular platform bed would had made the bed too high. My bedroom is small so I wanted the bed not too high up and take up space. I love it, I brought it down a few steps and took it out and just unfolded the box spring, took the covers out and placed it on the floor. This was a great investment and unique idea of a folded box spring, no installations or hassel. I am 63 years old and the weight was not a problem. If you looking for an idea to keep your bed not too high, I recommend this box spring. I really love it! ... show more

Each box has a pair of king box springs that fold in half. They are easy to haul and install and are very sturdy. Will be buying these again!

    • Best Box Spring I've Ever Bought
Size: Queen Pattern Name: Box Spring
One of the main reasons I purchased this one was it arrives folded, so no problem getting it in the door and through the house. I'm a senior citizen lady, and this was manageable to get out of box and set up myself. I can't say it was necessarily easy, but I managed it with minimal frustration. It serves its purpose well and I'm very happy I purchased it! ... show more

I just unfolded and it was good to go. Even was labeled what was the top and the bottom. I was able to carry it to my room, assemble and put on my bed all by myself.
