What people are saying
PURRfect scratching post

It’s a good thing that this wasn’t returnable to begin with because my cat found and destroyed it within half an hour. It’s still holding the bed and is a sturdy foundation, but apparently it is irresistible to feline members of the family.
Tempur-pedic mattress is the best!
Jan 17, 2026
We loved our old tempur-pedic mattress that was 22 years old. We ordered another mattress that needed a new base. We are in the process of returning our new mattress for a firmer one. There is no mattress that can even measure up to temper-pedic mattress and proper base. We are anxiously waiting for the new one to arrive.
So far, so good.
