Sleeping position Considering the original Purple mattress falls around a medium, or 5 on the scale, I think it's suitable for all sleeping positions. It's firm enough for a back or stomach sleeper, but also perfectly pressure-relieving for most side sleepers.

Those without back pain and who sleep on their back or stomach will likely favor a firmer mattress. Side sleepers or those with back issues may prefer something softer – although it ultimately comes down to personal preference.

Most heavier back sleepers will want a firmer mattress. To this group, the Purple mattress feels too soft, and is unable to properly support their back throughout the night. The heavier a sleeper is, the less supported they will feel by the Purple Mattress.

If you're interested in a plush mattress, check out the Purple Plus. It includes comfort layers with extra height for sleepers who prefer more plush mattresses. The top layer is made of the Grid which is a patented technology that eliminates pressure by being both soft and supportive all at once.

What's The Difference Between Firm and Soft? The obvious difference between a firm on soft mattress is the feel. A firm mattress is more rigid to the touch and has less give. A softer mattress will compress more easily when pressure is applied.

Mattress firmness is measured on a scale of 1 to 10 and refers to how soft or hard a mattress feels. On the mattress firmness scale, a soft is a 3-4, medium-firm is a 5-7 (with medium being a true 5), and firm is 8-10.
