My previous Sealy Posturepedic mattress was 18 years old. It was still in good condition however sagging a little so I felt it was time for a change. I decided to buy the same brand due to the excellent reputation. The sales person in the dept store was from Sealy and I was very happy with the purchase procedure. The mattress has good support and is very well made. Being a senior I'm glad to know that mattresses now don't have to be turned up side down for airing as there is only one side and there are air vents built into the mattress itself.
