What our customers are saying

"Our previous mattress was perfectly wrong for both my wife's and my body types, and we both experienced daily back pain. After about 3 weeks with the mattress, both of our back pains went away and have stayed away for months now."

Dan R.

"When our mattress got flooded I was glad to be rid of the awful sleep, but dreaded the thought of mattress shopping. We have been sleeping on our new mattress for going on 2 months now & my husband & I couldn't be happier."

Alli O.

"I have bursitis in both hips and could not find a mattress that I was able to sleep on without my hips burning. Finally found CST, submitted a body profile, and went to Connecticut to test it out. A full night's sleep on the first night."
