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.

(Ergoflex Mattress)

Ergoflex's best quality is its contouring memory foam. This high-density foam hugs sleepers and helps relieve pressure. It is less responsive than latex or poly-blend foam, offers great support, and is ideal for people struggling with soreness or joint pain. Plus, this company has been in business since 2006, making it an industry leader that can live up to its warranty.

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.

(Ergoflex Mattress)

While the Ergoflex provides good support, it can be too firm for some customers. Those with back pain may need this firmer feel, but other sleepers find the dense foam too hard. Keep in mind the mattress has body-shaping contour, but it may not be enough if you enjoy a pillowtop or sinking feel.
