The mattress is great. It has the best of all the other mattresses. The support is adjustable and held up for over 20 years. I have a lot of back and hip problems that are not a problem with this bed! The set up instructions are very easy to understand and it is very easy to use. I recently bought a new mattress as the air pump went out. I could have got a new air pump but was offered an amazing deal on a new mattress and considering the age of the air chambers chose the new mattress. Looking forward to another 20 years of comfortable sleep.
