Worst mattress I ever sleapt on!! I had high expectations for this mattress when I ordered it. And I was thinking that it was worth the money when I saw all the advertising. It's a very uncomfortable mattress. You can't sleep on it with two people in bed. It sinks down at the sides and you roll of the bed. The is no real support. It goes into a massive lump in the middle when there are two people on each side of the bed. For a medium soft mattress it's also quite firm. I was very disappointed and I sent it back. I have purchased mattresses less than half the price of this one and they are a million times better! Don't waste your money on this!
