You spend about a third of your life on your mattress, and an old or unsuitable one can mean back pain, overheating and restless nights. Buying a mattress online is now common, and many good options ship compressed in a box.
Below are popular mattresses available on Amazon and what each is best for. We have not personally tested these mattresses; our picks are based on materials, firmness and recommendations from respected mattress and product review sites. Check the return policy and trial period before you buy.
Quick answer
Choose by sleep position and body weight: side sleepers usually prefer medium softness for pressure relief, back and stomach sleepers often need medium-firm to firm support. Hybrids (coils plus foam) sleep cooler and bouncier; all-foam mattresses hug the body and reduce motion transfer for couples.
- Firmness: soft to medium for side sleepers, medium-firm for back sleepers, firm for stomach sleepers and heavier people.
- Type: memory foam (contouring, quiet), hybrid (supportive, cooler, bouncier), latex (responsive, durable).
- Temperature: hot sleepers often do better with hybrids or gel-infused foam. See why you get hot when you sleep.
- Couples: foam reduces motion transfer; check edge support if you share the bed.
- Trial and warranty: look for a home trial and a clear return process.

Tips for buying a mattress online
- Read the return policy and trial period carefully.
- Let a bed-in-a-box mattress expand for 24 to 72 hours before judging it; a new-foam smell usually fades.
- Use a supportive base or slatted frame suited to the mattress.
- Give your body 2 to 4 weeks to adjust.
- Add a topper later if it feels too firm.
A great mattress is just one part of great sleep. The 14-Day Sleep Reset helps with the rest, from bedtime routine to waking refreshed.
When to replace your mattress
Most mattresses last about 6 to 10 years. Sagging, lumps, waking with aches that ease during the day, or sleeping better in hotels are signs it may be time.
