Higher end Tempurpedic that started to suck after only 5 years or so for me and from day one for my wife. My back has gotten worse over the years and the mattress no longer offers the support I need.
I sleep in the recliner couch a lot, or on a single bed in the guest room that has a stiff regular mattress.
We're looking into getting something from one of the "local" NorCal or S. Oregon mattress makers, a traditional type.
Mattress shopping, like buying tires. Can't take them back for a full refund ..................USUALLY after they've been broken in and you find they're not suitable.
