We recently purchased a home and the owner had a new queen bed in the guest room that he gave us. Though my husband and I always have Kings, the sleep was wonderful. So we checked the tags and found out it was Serta Perfect Sleeper Elite. I began searching and Great Offer Stock had the best price by hundreds of dollars. We have now had our new King Serta Perfect Sleeper Elite Infuse and it is the best most comfortable mattress we have ever had. I have lower back problems and being "middle aged" the aches and pains of the day seem to dissolve into this mattress, I am sleeping well and all night not waking. We recommend this mattress to everyone who wants a full night sleep and waking up without any pains.
