The Good
(Greywing Mattress)

Easily, the best features of the Greywing are the cooling cover and firm support. Memory foam designs are great for keeping the body aligned, but are often hot. Many customers said the mattress helped alleviate back and hip pain, without waking up from overheating. Additionally, Greywing has a great customer service team that helps with every step of the purchase.

(Sleep Republic Mattress)

Individually pocketed springs are the highlight of this mattress. Sleep Republic arranges springs in five zones to target head and shoulders, torso, hips, knees, and feet. They also use tense steel springs around the border to increase edge support.

The Bad
(Greywing Mattress)

As with many memory foam mattresses, some customers find the Greywing too firm. It may not be right for sleepers who prefer a soft, sinking feel. However, it does have a comfort foam layer on top of the memory foam. If you've tried memory foam before, you'll notice this mattress is softer but still provides support.

(Sleep Republic Mattress)

Hundreds of springs make this mattress heavier to move and rotate. The shipping box has a built-in handle and wheels, but most need help carrying it up the stairs or placing it on a base.
