The product corresponds exactly to the description. The mattress is good value for money. I sleep on it while waiting to buy a real bed, the mattress does not hurt my back. The structure is easy to install, you just know how to properly place the small metal bars and their bolts. Very small downside, there is no jumper wrench provides little to tighten the bolts so must cope. And for me the wheels are required if the bed can not "ask" properly, they should be optional.
