Serta iComfortPro Granby
Best extra-firm mattress for back and stomach sleepers seeking cooling support.
This is the rare latex mattress that prioritizes rigid, uncompromising support over the typical sinking feeling of foam. It’s an ideal match for back and stomach sleepers who need spinal alignment, though those who prefer a plush, cloud-like surface will likely find it far too firm.
