Frequently asked questions

People with lower back pain may benefit from a medium-firm to firm mattress that prevents the hips from sinking, which can put added pressure on the lower spine. Some of the best mattresses for back pain provide ample pressure relief and zoned support. 

Ultimately, low back pain sufferers should look for a mattress that cradles the hips and keeps the spine aligned while considering their unique comfort preferences. 

Mattress firmness refers to the surface feel of a mattress, indicating how soft or firm it is. Mattress support refers to a mattress’s ability to maintain proper spinal alignment and provide adequate support to the body.  

Soft and firm mattresses can be equally supportive when constructed with high-quality materials. The key lies in the density and durability of components like memory foam, innerspring coils, or Purple’s innovative GelFlex Grid. 

A myriad of factors impact whether or not a firm mattress is better for you. If you experience back problems, sleep on your back, or are a heavier sleeper, a firm mattress may be better suited for you.
