Adjustable Firmness for Back Sleepers

Adjustability gives back sleepers room to tune support, but the comfort layers above the adjustable system still have a major effect on how the mattress feels.

Primary consideration

For many back sleepers, a useful starting point is balanced support through the torso and lumbar area. Treat that as a starting consideration rather than a medical prescription or universal firmness rule.

Why an adjustable system can help

You can experiment with support instead of committing permanently to one pressure setting. Couples can also preserve independent preferences when the mattress configuration supports separate sides.

Do not ignore the surface

A pressure change in the support core cannot turn thick plush comfort layers into a firm surface, or vice versa. Compare the complete construction.
