GhostBed's Flex Hybrid combines supportive coils with contouring foam for a comfortable feel. Our CNET sleep expert put it to the test to find out whether this high-end mattress is worth your money.

Saatva's most affordable mattress is a blend between the innerspring design of the Saatva Classic and a new-age memory foam. How well does it thread the needle?
