Our Verdict

Sealy Posturepedic Pro Highland Manor

Silk & Snow Mattress

The Sealy Posturepedic Pro Highland Manor is a hybrid mattress, while the Silk & Snow Mattress is an all-foam mattress, and that difference shows in how each one supports your body. The Silk & Snow's plush feel lets a wider range of side sleepers, including lighter people, sink in for pressure relief, while the firmer Highland Manor only offers that relief to average-weight and heavier side sleepers. That same plushness limits Silk & Snow's back and stomach support to lighter people, whereas the Highland Manor supports light and average-weight back and stomach sleepers well. The Highland Manor also hugs your body more closely, while the Silk & Snow lets you sink in without much contouring, so it feels more like sleeping in it than on it. The Silk & Snow isolates a partner's or pet's movements considerably better, while the Highland Manor offers much stronger edge support, giving you more usable surface and an easier time getting in and out of bed.
