My spouse and I were nervous about spending so much money on a mattress. My spouse has a history of severe back issues and no mattress ever worked for them just right. They would often wake up with significant back pain. We finally decided to take the chance on the TEMPER- after failed attempts with traditional mattresses, and a box mattress. We both could not be happier. This mattress is a dream come true. My spouse does not wake up with back pain anymore. Both of us can come to bed knowing we are gonna get the best nights sleep possible. I have never looked forward to coming to bed so much. It is nice and firm (firmest bed I've ever owned,) my body feels supported and comfortable every night. I can't recommend this bed enough.
