Common Questions

Mattress Firmness FAQs

It depends on your sleep position, body weight, and pressure points. Back and stomach sleepers generally need firmer support to keep the spine aligned. Side sleepers need softer contouring to relieve pressure at the shoulders and hips. The best way to know for sure is our free Discovery Experience. Our sleep consultants use body mapping technology to match you with the right feel.

Yes. Our medium options work for most couples because they balance support and comfort. For very different preferences, consider a split-king configuration with two different feels side by side. Each partner gets their ideal firmness without compromise. Ask us about split-king options at any store.

Our 100 Night Sleep Guarantee lets you exchange your mattress if the feel isn’t right. Sleep on it at home for up to 100 nights. If it’s not the perfect match, bring it back and we’ll help you find the one that is.

Yes. Heavier sleepers generally need firmer support to prevent excessive sinking and maintain proper spinal alignment. Lighter sleepers may prefer a softer feel because they don’t compress the mattress as deeply. The Discovery Experience factors your body weight into the recommendation so you get the right match.

With an adjustable base, you can change your sleep position to alter how the mattress feels. Elevating the head or knees shifts pressure distribution and can make the same mattress feel softer or more supportive. Some collections also offer comfort exchange options within the guarantee period.
