Why Stomach Sleepers Need Specific Support
Stomach sleeping puts extra pressure on the lower back. Without proper support, the hips can sink into the mattress, causing the spine to curve unnaturally. This can lead to morning aches and long-term issues. A mattress with zoned support, like the AS3 Hybrid, helps keep the hips elevated. The medium-firm feel also prevents the stomach from sinking too deep. This combination promotes a neutral spine position, which is crucial for comfortable sleep.
How the AS3 Hybrid's Construction Works
The AS3 Hybrid uses a 3-inch layer of Bio-Pur foam on top. This foam is responsive and breathable, conforming to the body without trapping heat. Beneath that, zoned pocketed coils provide targeted support. The coils are firmer in the middle third to support the lumbar area. They are also individually wrapped, which reduces motion transfer. The Celliant cover is designed to reflect body heat and keep you cool. This construction aims to balance pressure relief and support, which is ideal for stomach sleepers.
