We are full time RVers (live in our Recreational Vehicle). Mattresses that come standard in an RV are mere foam pads on a wooden plank. The quality has caused severe back problems for both my husband and myself. 

We are an elderly couple, both suffering from degenerative back issues, so the existing mattress only contributed to an already uncomfortable sleep. 

We are so thankful for this new addition to our bed. The gel not only helps keep my husband cool at night, but has given both of us an amazingly comfortable night sleep. 

Thank you for this wonderful product, and thank you for the best sleep we have had in three years. Two thumbs up!
