Tempurpedic Mattress the Worst EVER

About four years ago I purchased the most expensive Tempurpedic mattress available. Of course, the salesman said it was the best. Within ONE year there were deep sags where my husband and I slept. I weigh 85 pounds and he weighs 150. We are not real heavy people but the mattress still sagged. Now I having to replace it, less than five years old.
Don't buy this mattress - Yes, it feels good in the store but it won't last and therefore is NOT worth the money - I have purchased a Saatva and can't wait for it to arrive.
