Our Verdict

Casper Cooling Select Hybrid

Sealy Posturepedic Pro Highland Manor

The Casper Cooling Select Hybrid and Sealy Posturepedic Pro Highland Manor have different strengths. The Sealy is more supportive for most people, making it a good option for average-weight and lighter back and stomach sleepers. It has much sturdier edges, so it's a good option if you need a sturdy surface for getting in and out of bed. The Casper is a plusher mattress and provides better pressure relief for side sleepers.
