After reading ALL the reviews on this mattress in all the options (firm, soft, etc.) and in ALL the sizes (twin, full, queen etc.) I truly thought I was getting a deal here, vs spending my money on a tempurpedic (leading memory foam) mattress for my 2.5 year old. I tried it out and was not impressed. I have owned 2 tmprpdic mattresses and this did not come close. My husband slept on it for 2 weeks straight while we had company, and there seemed to be a permananent indentation after! However, after a month it did go back to "normal". All in all I think it will last us a couple more years, but certainly not the quality, or grade i expected.
