Medium

Suitable for all sleeping positions and average body types, a medium mattress combines balanced cushioning, reliable support, and controlled sinkage for versatile comfort.

Medium-Firm

Best for back and combination sleepers with average to heavier body types, a medium-firm mattress provides supportive comfort, light cushioning, and reduced sinkage.

Ideal for back and front sleepers with heavier body types, a firm mattress delivers strong support, minimal cushioning, and very little sinkage for a stable feel.
