Sealy Shelby Posturetech Mattress - Firm is rated 4.56 out of 5 by 25.
Rated 4 out of 5 by from Sealy - Sealy Shelby Posturetech Mattress - Firm Hard to start, but after a couple of nights sleep on the mattress it has settled and softened and is very comfy. I have a bad back and find it hard to find a good mattress that I can sleep on, but not had as many good nights' sleep since I bought it.

Rated 5 out of 5 by from Super comfy I bought this to replace the mattress in the flat I moved into and it is so comfy. I suffer from scoliosis and constantly have an achey back, but this mattress helps me to get a comfy sleep and wake up in the least amount of pain possible to me. It is properly firm, but the soft layer at the top lessens the hardness slightly, meaning that you have the support of a solid mattress but the comfort of a soft one. Best of both worlds

Rated 5 out of 5 by from Great for bad back sufferers! Bought a month ago and I no longer wake up stiff from back ache! Only fault is no protection over the little metal tabs that keep it all together and NOT happy dreams didn't send my free mattress protector

Rated 5 out of 5 by from Quality Mattress It's a firm mattress, but not overly firm. As a side sleeper I find this mattress to be comfortable both on my side and on my back. Since my mattress was delivered I have slept very well.

Rated 5 out of 5 by from Best Sleeps Ever! My mattress arrived last Wednesday and ever since I've had the best and comfiest sleep I have had in ages! As I suffer from a frequent bad back and back pain, I decided to go for a much firmer mattress... and I'm so pleased I chose this one. Fantastic!!
