This mattress  is an absolute joke. How anyone can give it good reviews really baffles  me. The mattress is extremely  poor quality. The whole thing sinks in when I sit on it. It sinks down a lot even with my nine year old child sitting on it.  This mattress  feels the same as my 10yr old mattress. Totally dissatisfied  with the quality of this mattress. It's  barely worth  1/5 stars!!!!!
