This "box spring" has no springs, but it looks identical to a box spring. But the huge bonus is that due to it being in a smallish box, it will fit through virtually any doorway or up/down any set of stairs. For that reason, it is a terrific bargain. It is also extremely easy to put together and very sturdy. Don't hesitate to buy this if you have a tight space to maneuver or even if you don't!
We was in need of a Bed Box Spring. So, I browsed Walmart Website. And we found exactly what we needed. But, we never purchased a Box Spring that you had to assemble. But the assembling was easy. Thank Walmart, again for coming through in our time of need.
Whoever came up with this idea for the easy assembly boxspring is a genius. Box springs are one of the hardest things to move since they do not bend in are difficult to get up a stairwell. And this being made of metal is more sturdy than a wooden framed one this will be very easy to disassemble and fold up when I move and transport to the next home. I wish I thought of this myself. Pure genius!
This was so easy to assemble. It looks intimidating when you first unbox it but it's nothing more than just snapping parts together. No tools needed! I ordered a king size and assembled this in less than 10 mins. The cover is easy just unzip all the way and tuck in box spring then re-zip. It's very sturdy not squeaking or noises and is supporting my hybrid mattress nicely
Did NOT believe this could be real but it is!! This product is amazing and soo easy to use and set up. Now will say you need space to add the covering if assembling alone because it is a tight fit and the frame is large depending on the size but solo i was able to get it done. The assembly is another story it took alll of about 20 minutes alone for me set up the frame. The foldable equipment was amazing strong and sturdy the rods fit so snug and takes a little force to snap in but recommend working from the middle outward when inserting the rails. been sleeping on it with my 150lb queen mattress for over 2 weeks and hear nothing and feel secure. Love this produce and highly recommend!
I was uncertain about buying this bed frame, but glad I did. It was easy to put together and is holding up well for two adults. I did purchase a bunkie board to ensure a solid surface for our mattress and to decrease risk of bending one of the metal slats. After 2 weeks , I can say it's working and I've heard it squeak maybe twice.
This box spring is perfect. Easy to assemble, no tools needed! I was able to set it up and put the cover on in about 5 minutes. It's super sturdy and looks great. I'd recommend it to anyone looking for a nice, strong, well priced foundation.
About this item a few months ago and realized they sent the wrong one. The wrong size explained that to them, and I turned around and sent me another one. I cannot lift it and I drive a card, not a truck to return it to get my refund and they give me until today. March 1st. Please do not buy this item.It's just getting worse and worse on Walmart's end.I will be back to do a better review once they fix this issue!! when I tried so schedule for them to pick it up.They explained to me that it was cost me for them to come and pick up a replacement , but they don't want sent the extra box spring trash.
i ordered this mattress because it was ''medium firm''. it is so firm it's like sleeping on a board. i spent another $70. on a pillow top mattress pad, and it's still too firm. other than that it's ok if you like an extremely FIRM mattress. i did not ask for a refund because i could not move it by myself to donate it anywhere. the paper work said if i didn't like it to donate and send proof of the donation and i would be refunded. i am 72 and disabled, the reason why i did NOT want a very firm mattress.
Horrible! Was fine setting up however weight capacity is not true to size. The bed sunk and the main frame of the box spring snapped. Definitely defective. It's my fault for buying such a cheap box spring.
