Reviews ethics statement What to consider Firmness A firm mattress will offer more support while a soft mattress will be more pressure-relieving. Medium mattresses fall in the sweet spot right in between. The right firmness level for you depends on your sleeping position. Sleeping position Side sleepers should consider a medium to soft mattress that cradles the hips and shoulders. Back and stomach sleepers should consider a medium to firm mattress that keeps the spine in a straight alignment. Switch between positions? A medium firmness level can accommodate all sleeping positions. Feel Coils and latex foam give a bed more bounce, while memory foam and poly foam make a bed feel more cushy and pressure-relieving. The feel of your mattress will depend on the types of materials it has on the inside. Construction There are essentially two mattress types, hybrid and all-foam. Hybrid mattresses are constructed with steel coils and foam, but all-foam mattresses are just as their name implies. Body Type Hybrid mattresses tend to be best for people who want extra support and durability. Sleepers over 230 pounds in particular should consider a hybrid over an all-foam mattress because its more supportive, durable and long-lasting. Performance Motion isolation, edge support and temperature are important features for couples or people who sleep hot to consider. Hot sleepers should consider a mattress that boasts special cooling features. Couples want minimal motion transfer and a strong, supportive bed perimeter.
