Tried out king size for the master bedroom and it was just too large to justify the space so we moved the set to our guest room.
It has maybe been used 3 or 4 times and sheets washed each time.
Non smoking and pet free home
Still in new condition, we moved and had the mattress plastic wrapped and has not been used in our new house
10 inches thick
Memory foam top very comfortable
Mattress only, the bedroom set was sold before we moved
