How to pick the right mattress for your need

The right mattress depends on three factors working together: your primary sleep position, your body weight, and any pain or health condition you're working around. Getting all three right is what separates a mattress that feels fine in the store from one that still works after 90 nights.

• Sleep position: side sleepers need more contouring at the shoulder and hip (medium to medium-soft, 4-6/10); back sleepers need lumbar support without sinking (medium-firm, 5-7/10); stomach sleepers need a firm base to prevent spinal hyperextension (7-8/10).
• Body weight: sleepers under 130 lb compress foam less and usually do better on softer models; sleepers over 230 lb need denser foams or coil-hybrid construction to avoid premature sag.
• Pain or condition: zoned support (dual-coil lumbar zone on the Saatva Classic, HIVE on the Amerisleep AS3) directly addresses the alignment failures that cause back, hip, and shoulder pain during sleep.

If you are unsure where to start, the Saatva Classic in Luxury Firm is the most versatile option across sleep positions, body types, and firmness preferences. Its three-firmness lineup means couples or sleepers who are uncertain about their ideal feel can narrow it down with the 365-night trial.
