Excellent product. I was a bit leery at first because this is nothing like the "box spring" I was used to. I waited days before putting it together because the picture showed so many pieces. Assembly was so simple that I was embarrassed for having waited. There were six main pieces, six connector pieces, six screws and a cover. It's very sturdy and fits well into a regular bed frame (my frame fits, full, queen or king). Once the cover is on, it looks like what I've been used to. **NOTE** Hold cover at bottom when placing on placing on frame so sides appear smooth. EXCELLENT PRODUCT!!!

Exceeded expectations.

I was skeptical about this box spring when I ordered but it exceeded my expectations now that it's assembled. It is super sturdy yet super lightweight. It's also super easy to assemble from just looking at the diagram and there are no tools required. I am now wishing I had this when I lived in my apartment in London because it would have been more practical than the traditional box spring, which we ended up having to throw out because we didn't t have room to store it when the spare bed wasn't in use.

I really like my queen box spring. It was super easy putting it together. The price was reasonable and it arrived on time. I would definitely recommend this if you have a wooden one that makes a lot of noise.
