I have owned Serra mattresses since 1978. They have all been comfortable and long lasting. I just replaced the one used in my guest room for 40 years. The new mattress is very comfortable and and affordable. I bought for my 92 year old mother who has been having trouble sleeping because of back and upper arm pain. After spending her first night on the new Serta mattress, she had her first night of restful sleep in weeks. Our new mattress offers the comfort we expect from a Serta mattress.
