Mattress Buying Guides
Straight answers to the questions shoppers ask most, organized by health concern, sleep position, and brand. Find your guide, then test your shortlist in store.
Start with how you sleep, then adjust for your body weight and the feel you like. Side sleepers often prefer a softer feel that relieves pressure at the shoulders and hips. Back sleepers often do well with medium to medium-firm support. Stomach sleepers usually need a firmer surface so the hips don't sink. Then factor in sleeping hot and sharing the bed, and test your shortlist in person. At Sit 'n Sleep's 37+ Southern California stores, BedMATCH fitting helps narrow down mattresses to try.

About DrewMattress Buying FAQ
What type of mattress is best?
There is no single best type. Memory foam suits side sleepers and couples who want close contouring and little motion transfer. Hybrids add coils for bounce, airflow, and edge support, which helps hot sleepers and heavier sleepers. Latex is responsive, durable, and naturally cooler. Innerspring is the firmest, most traditional feel and often the most affordable. Read: Hybrid vs. Memory Foam Mattress
What firmness should I get for my body weight?
Body weight changes how firm a mattress feels. Lighter sleepers often find a firm mattress feels harder than its rating, while heavier sleepers sink further and usually need more support underneath. Treat the firmness rating as a starting point, then test it lying in your usual position. Read: How to Choose Mattress Firmness
What size mattress do I need?
A queen (60 by 80 inches) is the most popular size for couples. A king (76 by 80 inches) gives each sleeper more room, and a California king (72 by 84 inches) is narrower and longer for taller sleepers. Measure your room first and leave space to walk around the bed. Read: Mattress Size Guide
How often should I replace my mattress?
Most mattresses wear out after roughly 7 to 10 years, depending on materials and use. Sagging, new aches when you wake up, and sleeping better away from home are common signs it's time. Read: When to Replace Your Mattress
