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: Easy 45 Minute Assembly with sticky notes - I knew there were going to be a lot of parts, so I decided to be as organized as possible. After opening the box, I marked each group of items with a sticky note to make assembly as easy as possible. It took 45 minutes total to label, assemble, and put the cover on. I especially loved the mini ratchet tool that was included; it made tightening everything much faster and easier than using a standard allen wrench. Everything fit as expected and was easy to move into our rolling adjustment frame. The King mattress fits nicely on the metal box spring and does not slide around at all. It looks great and feels very solid. We are looking forward to having family visit and hope they enjoy the comfort. If you take the time to organize the pieces first and use the provided ratchet, this is a very straightforward and high-quality setup
Review: Best Box Spring Ever! - This product is great, I am 100% satisfied with this purchase. I am using this box spring with a Nature Sleep memory foam mattress. If you have an innerspring mattress your mileage may vary. My review as follows will cover several different aspects of this product and why they are great. Portability: Who knew you could assemble a box spring instead of lugging around a 50+ pound bulky wooden frame? Once assembled, the frame is lightweight and much easier to move around than a traditional box spring. The next time I move I am just going to take it apart instead of it taking up space in the moving truck, very economical in that sense. Assembly: Assembly was very easy, no mechanical inclinations required from the assembler. The set comes with an allen wrench/hex key and you use that to hold bolts in place while you tighten wingnuts with your fingers. Please ignore any reviewer of this product who said it was too difficult to assemble, took too long, or had confusing instructions, they are either lazy or completely incompetent. It took me about an hour to assemble by myself, and it would have taken even less time if I hadn't been half watching TV and drinking a beer while I was putting it together. The instructions aren't written words, but pictures showing which pieces to assemble with which bolts, but if you ever built a Lego set when you were a kid you should be able to handle this. It is easy to tell which pieces should be facing up during assembly, because most have a 'this side up' sticker. The pieces that don't, it either doesn't matter which side is up or you can tell which side should be up because of the notches the slats will fit into at the end. The Cover/ Looks: The zip cover looks nice and the white sides are a soft plush. Make sure you sweep your floor before zipping the cover on though or you might get dirt all over the nice white part. Some people said that the cover ripped when they were zipping it up, that was not the case for me. The cover is a very tight and perfect fit, but the white sides stretch. So when you zip it on, don't just yank on the zipper as hard as you can, pull up on the white parts that stretch and it will make the zipper easier to close. Durability: It seems sturdy enough to me. I have had for two weeks, no complaints. I have unzipped and re-examined the frame and it has not bent or buckled under the weight of two people or any vigorous activity. Could you bend the metal of the frame after you put it together? I guess you could if you tried to, but why would you do that deliberately? Putting a mattress on top of it and using as intended should leave you with no issues. I hope this review provided all the information needed to help in your purchase decision, and I am sure you will be satisfied with this box spring.

### ⭐⭐⭐⭐⭐ Good buy!
*by H***. on December 27, 2025*

Super easy to put together, sturdy, and fits perfect. It’s also light enough that I could drag it to the bedroom after putting it together and I’m pretty weak lol
