Our Verdict
Beautyrest Black
Purple Mattress
You might prefer either the Beautyrest Black or the Purple Mattress depending on your needs. The Beautyrest is a plusher hybrid mattress that you'll sink more into. It offers better pressure relief that makes it more comfortable for most side sleepers. The Purple offers worse support and worse pressure relief overall, but it's a good option for heavier side sleepers and lighter back and stomach sleepers. It has a much less enveloping feel and offers outstanding cooling, making it the better option for hot sleepers.
