Who is a ‘firm’ or ‘extra firm’ mattress best suited for?

Firm mattresses are best suited to dedicated back sleepers, or those who require an extra firm mattress for various reasons.

What’s the difference between ‘firm’ and ‘extra firm’?

Aside from one being firmer than the other, the difference between a ‘firm’ or ‘extra firm’ mattress comes down to personal comfort preference. Both offer the supportive benefits of an adaptive, firm sleeping surface. It’s up to you which one feels better. The best part about our adjustable TrueFirm Mattress is that you have both, so you can try each side and sleep on the one best suited to you.
