Your mattress affects your sleep quality more than almost any other factor. A bad mattress can cause back pain, joint stiffness, and frequent position changes that fragment your sleep. But choosing the right mattress is overwhelming. Here's what the research says about mattresses and back pain.
A 2015 study in Sleep Health reviewed 24 studies and found that medium-firm mattresses (5-7 on a 10-point scale) improved sleep quality and reduced back pain compared to firm mattresses. The sweet spot is firm enough to support your spine's natural curve but soft enough to cushion your shoulders and hips.
Conforms to your body shape and distributes weight evenly. Good for pressure relief and side sleepers. Downside: can trap heat. Look for gel-infused or open-cell foam for better cooling.
Traditional coil mattresses. Good support and airflow (cooler than foam). Downside: less pressure relief, can sag over time. Look for individually wrapped coils for better motion isolation.
Combines coils (support) with foam or latex on top (comfort). The best of both worlds for most people. More expensive but offers good support, pressure relief, and cooling.
Natural or synthetic rubber. Responsive, durable, and cooler than memory foam. Good for people who want support without the "sinking in" feeling of memory foam. More expensive but lasts longer.

Good mattresses range from $500-2000 for a queen. You don't need to spend $3000+ (diminishing returns), but avoid mattresses under $300 (usually poor quality). Many online brands (Casper, Purple, Tuft & Needle) offer good quality in the $800-1200 range.
Online mattresses usually offer better value (lower overhead) and generous trial periods (90-365 nights). In-store lets you test before buying, but 5 minutes in a showroom doesn't tell you how you'll sleep on it for 8 hours. The best approach: buy online with a long trial period and return it if it doesn't work.
A mattress topper can improve an existing mattress that's too firm or slightly worn. It's a cheaper alternative to a new mattress. Memory foam or latex toppers (2-3 inches) provide the most benefit. But if your mattress is old and sagging, a topper won't fix the underlying problem.
