Sturdy Metal Box Spring

Over all quality of this product is good and sturdy. Easy to follow instructions for assembly the cover is like a fitted sheet with straps to hold it in place while this can be put on with just one person I recommend having two people to do this it makes it easier to put on.

We ordered a queen size. It was inexpensive. It was easy to put together. It's very sturdy. When you put it together, leave the slats out until it is in place inside the frame or on the floor. The slats will fall out if you turn it sideways to move it. The cover is also not a full cover. The elastic goes under the corners and the material does completely cover the metal that is seen.

Yay I got a box spring finally !

I couldn't find a boxspring that would fit up over my weird staircase. I came across this on walmart.com and I figured I would give it a try. It easily fit up. The stairs assembly was very easy all in all. It was a great purchase.
