I concur with my colleagues. A stomach sleeper should sleep on a firmer mattress whether it's latex or inner-spring/pocket coil. As well, be sure to use a very flat pillow or no pillow at all.

The main concern for stomach sleepers is to avoid a really soft mattress. A soft mattress tends to make a tummy sleeper feel like they're lying in a hammock...the spine tends to curve the wrong way! So, a medium or medium firm is a better choice. Whether you prefer an innerspring mattress or foam (latex or memory foam) is a personal comfort choice. Find the most comfortable bed in your price range and sleep well! From our products, I'd recommend the Keetsa Tea Leaf Classic or Bed in a Box PacBamboo as a comfort choice, but this is about what you like, not what I sell!!

A product with strong support characteristics and a higher ILD / harder surface comfort would be desirable, generally speaking. Your lower back already has a bit of a lordotic (forward) curve, and sleeping on a mattress that allows too much sinking will accentuate this forward curvature, potentially allowing for posterior compression of the vertebrae. Your own physical characteristics (somatotype, girth, mass) will determine how much sinking you can tolerate. Many orthopedic physicians and chiropractors would want you to try to sleep on your side, if possible. Hope that helps.

Most Chiropractors will ask you to work at NOT being a stomach sleeper, as it is not the best position for your spine alignment and particularly not for your neck. That said, a flatter, non-yielding surface tends to favor side sleeping, as it prevents the neck kinking. The softer the bed, the more pressure on the neck.

Firm!! If you have a sleep partner who sleeps on their side, it will be a lot more difficult to find a compromise.
