    The first thing I have to comment on is that I ordered this box spring on the 13th and it arrived the early morning of the 15th! Super fast shipping, and the shipping was free! Second thing to comment on is the price. A great box spring for only $109! I opened the box yesterday and looking inside, I have to admit, the setup looked pretty intimidating. But today, I finally decided to put on my big girl panties and build this thing! Setup only takes 30 minutes max! The instructions are super easy and are one-sided on a single sheet of paper, with pictures to make it that much easier to follow. 75% of the work you do with your bare hands and 25% with a basic screwdriver. If you have a power drill, this shouldn't take you anymore than 15 minutes to set up. Also, the foundation cover is super soft and thick, much better than most conventional box springs that are already pre-built. I'm so glad I chose those over the bi-fold box spring they have on this site. Reading those reviews, it looked like the bi-fold didn't give much support, but this box spring is made of sturdy wooden panels. It fit my full mattress and bed frame perfectly. You can't go wrong! Highly recommend.

    Easy to assemble,very sturdy and comfortable

    This is the 2nd box spring I bought from Walmart, the same one. It was easy to assemble and it is solid wood not press board. My 1st box spring broke due to inferior wood and my other box spring squeaked every time I got out of bed, so I replaced them. If you have power tools the job will be done in a matter of minutes.

    Everything I expected!

    We have had this product for about a year now and it is holding up very well! It was easy (considering that it is King size folded in half) to bring upstairs and into the bedroom and fold out onto the bed frame/support by myself. I am 6', 190 pounds, but I am sure someone smaller could do it too, although a helper is the best way in my view. The price is right and the look is good too. We have a memory foam mattress (also from Walmart, but I don't recall the brand right now) that was a much lower price than the name brand versions frequently advertised. I also looked into that very carefully before choosing it (by side by side comparisons of the products) and the big difference was in name and price only. We got the mission frame from someone that advertised on Craig's list (like new!) and so we have an entire King Size bed with blankets and sheets (sheets also from Walmart, 400 thread count) for well under 1,000 dollars and my Wife and I are very happy with it. I highly recommend a mattress protector to everyone. Spills happen.

    It is exactly what I expected.

    I am elderly with some mobility issues. I was able to easily assemble this platform by myself. The directions are very simple and straightforward; however, I had to put a couple of cross slats in position before I fully tightened the corner bolts. Otherwise it appeared that the the cross slats are slightly too long. They were, in fact, just right. The cover was easy to put on and it looked like the sales picture. Mine was a queen size.

    When I saw this online I was doubtful despite the great reviews. It was easy to assemble & exactly as described. Such a great idea & value.


    when i got it i had forgot it had to be assembled the box arrived and i thought it was something else i had ordered because it didn't look like a box for a box spring but opened it up and took it out and it was the boxspring it was easy to assemble its strong and i'm happy with my purchase plus the price was right lol and the shipping was superfast
    When looking for a new mattress I knew I needed the box springs too. Then I ran across this mattress support. I love the idea that I can dissassemble it for easy moving or storage. And I love the idea that I can wash the cover. You can't do either with a traditional box springs. I was able to move this into my room by myself and assemble it by myself. It is very practical and the price is awesome. I think this will outlast a more traditional boxsprings and certainly be healthier for dust mites and back support. I put this on my antique iron bed and needed to chisel out a little wood for it to sit in the frame properly (they don't make modern frames the same way as this antique one). I never could get traditional box springs to sit the way it was intended. So this is a big plus. If you have a regular frame you shouldn't have to modify at all. I ordered a 6 inch memory foam mattress to use on the mattress supposrt and have been extremely pleased. I would recommend this to anyone. Super happy!!!

    Cheap and quick solution for a box spring

    I was surprised to receive the box spring with all the complete parts, after only about three days shipping time all the way from Baltimore to the west coast. It only took about half an hour to assemble and everything fit perfectly. The instructions are sparse, but it's quite a self-explanatory process. Long boards are the sides, short boards are head- and foot-boards, bolts go in the holes, slats sit on top, screws go in the pre-drilled holes. I would be amazed if someone could mess it up. I expected half the parts to be missing, but no, all there! I think I'm most pleased because shipping only cost $3. I'm sure that's a mistake of oversight because the package was extremely heavy and should have normally cost around $50. There was simply no other choice that competed with this item in cost. So far I haven't fallen through to the floor yet, seems appropriately sturdy. Well done Walmart; you somehow beat Ikea, Amazon, and Craigslist on this item for me.

    Great alternative to a "normal" box spring

    My husband and I bought this box spring for our Sealy King sized mattress. We looked into a more traditional box spring and found out that it would be upwards of $225! With this coming in under $150 we were more than happy to give it a try. Please understand that it comes UNASSEMBLED! However, the assembly isn't too bad at all. It took me about an hour to do by myself - which is longer than most people reported BUT I am 7 months pregnant and I took plenty of breaks. We've been sleeping on it for a week now and after the first 10 minutes we haven't heard any wood creaking or any noise at all like others have reported. In fact its been perfect!! It is VERY secure and looks nice with the cover on. We also appreciate the fact that it can be taken apart for the next time we move! I would definitely recommend this to anyone looking for an affordable solution to a traditional box spring!

    overall a good product

    the frame itself went together very easily and the instructions were clear except one of the pictures showed an outside slat facing the wrong way. the trouble came when trying to fit the top slats into the notches- they seemed to be too long to fit, but luckily a strong neighbor was available to help and he was able to expand the frame by muscle power and get the slats to fit in the top notches. i assume this is par for the course but no way could i have done that myself (i am a small gal!) the cover was much nicer than expected and i was very impressed with the quality. the entire frame is fairly lightweight but seems sturdy enough to last for a long time with normal bed use (vs kids routinely jumping on it). i got a king size and it fit our bed with the correct dimensions. overall, this is a good product, but you will need some muscle to get the top slats in!
