How do I choose the right mattress firmness?

Firmness depends mainly on your sleep position and body weight. Side sleepers need a softer mattress (3-5 out of 10) to cushion shoulders and hips. Back sleepers need medium-firm (5-7). Stomach sleepers need firm (7-9) to prevent lower back sag. Heavier sleepers over 230 lbs should go one level firmer than recommended for their position.

What is the best mattress material for back pain?

Medium-firm hybrid mattresses are best for most back pain sufferers. The foam or latex comfort layer contours to lumbar curves while the coil base prevents sinkage. Memory foam is also effective if the mattress has a firm support core. Avoid mattresses that are too soft, which allow the hips to sink and misalign the spine.

How long should a mattress last?

A quality mattress should last 7-10 years. Latex mattresses last the longest at 10-15 years. Hybrid and innerspring mattresses typically last 7-10 years. Memory foam mattresses last 7-10 years depending on foam density. Signs you need a new mattress: visible sagging over 1 inch, waking up stiff, or noticeably better sleep at hotels.

What is a mattress trial period and why does it matter?

A mattress trial period lets you sleep on the mattress at home for a set number of nights (typically 90-365 nights) and return it for a full refund if you are not satisfied. Your body needs 30-60 nights to fully adjust to a new mattress, so trial periods matter enormously for online purchases.

Should I buy a mattress online or in a store?

Online mattresses typically cost 30-50% less than in-store equivalents because brands skip retail markups. Online brands offer long trial periods (100-365 nights) and free returns. In-store shopping lets you test firmness immediately but prices are higher and you must rely on a brief showroom test.
