Firmness, Benefits, and Ideal Sleepers

The Serta Mattress in a Box—available as an 11-inch firm hybrid or 12-inch medium hybrid—offered by SleepySal provides a firm support level designed for those who prefer a sturdier, more supportive sleeping surface. By combining responsive coils with high-density, gel-infused memory foam, this mattress delivers exceptional stability that helps maintain proper spinal alignment throughout the night.

Benefits of the 11-Inch Firm Hybrid Mattress:
This option reduces sagging for heavier individuals, minimizes sinkage for better lumbar support, and prevents excessive curvature in the lower back. These features help alleviate back pain and promote healthier posture. The firmer feel also improves ease of movement, making it easier to switch positions without feeling stuck. Ideal for back and stomach sleepers, as well as those with back or hip concerns, this mattress supports optimal body alignment and reduces pressure buildup. The combination of firm comfort and cooling gel foam ensures a cooler, more refreshing sleep experience.

Benefits of the 12-Inch Medium Hybrid Mattress:
Medium firmness offers balanced contouring that relieves tension in the shoulders and hips without allowing the body to sink too deeply. This “just right” feel suits most sleepers. It adapts to various sleeping positions, absorbs motion to minimize partner disturbance, and promotes uninterrupted sleep. Ideal for side, back, and combination sleepers, the medium-firm 12-inch profile provides versatility for couples with different sleep preferences or individuals who switch positions throughout the night. The added thickness enhances durability and luxurious comfort, delivering soft cushioning along with dependable support.
