## Description

We like to think of a box spring as the backbone for your mattress. The best kind should be flat, level and built to keep your mattress in tiptop shape; and that’s just what the Smart Box Spring does! With its easily assembled, dependable steel structure, you can rest assured that your mattress will be sitting pretty. An included poly jacquard cover blends with the rest of your bedroom, and with a variety of different thicknesses to choose from, you can pick the one you need to customize the height of the bed. All packed in a compact shipping box with everything included, even our 5-year worry free warranty! Now that’s peace of mind you can sleep on.

Review: Very sturdy and surprisingly quiet - I’m honestly impressed with this foundation. I bought the king size and was expecting it to be heavy and complicated, but it was actually very easy to put together. The frame feels solid once it’s assembled, and it doesn’t wobble or shift when you get in and out of bed. What I like the most is that it makes absolutely no noise. No squeaks, no movement sounds at all. The support is firm in a good way, and the surface feels steady under the mattress. It also doesn’t weigh as much as I expected, so moving it around wasn’t a problem. Overall, it looks clean, feels durable, and holds the mattress perfectly without sliding. The height is perfect to match the regular bed headboard. (4 " works )Great buy.
Review: Strong and yet affordable - Had never heard of a box spring that is not made from wood. At first, I was skeptical to order a box spring from steel. My skepticism then got slightly worse when I read some negative reviews about "OHM, it takes too long to assemble!" Being an engineer and an optimist upon reading majority of great reviews, I went ahead and placed an order for queen box spring. Not only it arrived in time but it was also well-packed. It is heavy and you will need 2 people to carry the box from outside to your bedroom. Once I unopened the box, I was surprised to find the individual pieces tied up in groups based where they all go. Every single piece is numbered and lettered. A piece numbered "1" connects to another piece numbered "1", numbered "2" connects with another numbered "2". Very simple and easy. The kit also comes with tools. The part breakdown is as per below: A (inner long rail) = 2 B (inner short rail) = 1 C (outer short rail) = 2 D (outer long rail-1) = 2 E (outer long rail-2) = 2 F (Slats) = 10 S (shortest screws) = 8 M (mid-length screws) = 4 L (long screws) = 2 H (nuts) = 10 The best advice is that open the box, remove the cable ties, lay out all parts on floor as per the intended connection and get an idea of who connects to who (without actually assembling). It is otherwise called a "raw" or a "draft" assembly". Once it is done, it takes 30 minutes MAX to connect all components. I then put the cover on it and zipped it up. Voila, it was now ready to be placed on the bed. The moment of truth was moments away. My daughter and I lifted it up and placed it on her queen bed. It fit perfectly. We then put the mattress and lied down on it. It is very sturdy and does not squeak upon rolling. Overall, it is very strong and affordable. Here is the best part. It can be unassembled and moved to another place much easily (than the traditional wood box spring). I highly recommend it. Buy it with full confidence!

### ⭐⭐⭐⭐⭐ Straightforward assembly, solid once together
*by S***H on April 28, 2023*

After putting this boxspring together, I don't think I'll ever purchase a pre-assembled one ever again! Assembly was pretty easy, and the box has everything you need, including an allen wrench and a small ratchet. The instructions were specific about what order to do things in, but I just laid the parts out on my floor in their correct position, and snapped them together as I worked my way around. The powdercoating on the pieces feels high quality, and I did not notice a single sharp edge or corner. The pieces are all light but quite sturdy. I wanted a solid surface for a memory foam bed, and this seems to fit the bill. Something that worried me a little was whether the metal pieces would clank against each other when everything was assembled, but I think it'll be nice and quiet. The only place that metal could touch metal, there's a thin foam pad to prevent noise. At first I thought the cover was slightly undersized, but after getting all of the corners on, the material on the edges curves up over the top just a little on each side. It looks very nice once the mattress is in place. The ease of breaking this down to move it is a huge selling point. I don't plan on moving again in my life, but a large boxspring is a PAIN to move up and down stairs. This breaks down into a small enough package that you could easily move it up a spiral staircase. I would definitely recommend this to anyone who wants a sturdy base for their mattress, and especially to someone who has a tight pathway to their bedroom.
