We have had 7 or 8 mattresses. We keep thinking we will happen upon one  that really lasts more than 3 years, but with arthritic needs, can truthfully say I have never had a mattress that lives up to its claims. We have had Serta, Sealy, Select Comfort, Simmons Beautyrest and and older company Tempur pedic.

What is the trick to finding a reliable one? Was going to try Sleep Number but it's the price of a small car! YIKES.
