Mattress Buying Guides
Expert guidance to help you find the right mattress — by sleep position, health need, or brand comparison. Written by the Sit 'n Sleep team and backed by 45+ years of helping Southern Californians sleep better.
Buying a mattress is one of the most personal decisions you can make — and one of the most confusing. The right mattress depends on how you sleep, how much you weigh, whether you sleep hot, and whether you share a bed. Most mattress marketing does not make that easier.
These guides are different. Each one is written to give you a clear, honest answer to a specific question — so you can walk into a Sit 'n Sleep store knowing exactly what to look for, what to test, and why. Every guide is backed by our 45+ years of helping over 3 million Southern Californians find the right mattress.
All guides include in-store testing advice. Reading is a starting point — but the only way to know if a mattress is right for you is to lie on it. Every guide links to our 37+ Southern California locations and our BedMATCH diagnostic fitting technology, which matches your body profile to the right mattress in store.
