After sending the wrong item, Amazon quickly fixed the problem and sent the box spring within a few days. I was on a tight schedule to get this bed set up for my 97-year old mother who came to stay with us for a month. So kudos for how quickly they responded and fixed the problem.I looked long and hard for the "perfect" box spring for my 97-year old mom. There were so many different features I felt she needed and this one fit the bill perfectly! It's the only one with a fabric cover, which gives it a nice finished look. At least one reviewer said to lay out all the pieces before putting it together, so I did that. GREAT SUGGESTION! It made putting the bed together much easier than if the parts had been scattered all over the floor. Once you figure out the difference between the "H" shaped pieces (take a good look at the illustrations in the instructions), how it fits together pretty much makes sense. I put it together myself in about a half hour. The only thing I did was ask my husband (who is about twice my size!! LOL) to tighten all the screws, etc. Once we put the mattress on it, we laid down on it to make sure it felt sturdy and stable. I was a little concerned that the mattress would slip and slide, but that hasn't been an issue. I would maybe suggest a more "gripping" type of fabric for the side that touches the mattress, or slightly raised lips around the metal frame to hold the mattress more securely. But truly, it's working out really well so far! Very happy with this purchase.
