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.

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!

Easy Assembly Box Spring

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!
