MedX is not specialized in pillow production, but they do produce high-quality therapy assist equipment and some body support utilities. This pillow, however, has got nearly a thousand of review, mostly 4-5 stars, from Amazon buyers.
Just like the two competitors above, the MedX is made from memory foam, but its foam is of medium firmness. Reviewers mention that the pillow is firm enough to keep your knees apart but still has its softness that when you curl up into a ball, it doesn’t press against your calves like other hard pillows. The size of the pillow may be listed in the small pillow list and for some big size sleepers, it may not fit (its size is 10” x 6.5” x 8”, you should consider carefully before deciding). Removable cover is available for washing and highly breathable. Fully refund with no question asked is guaranteed. You bear no risk but to spend a night to check it!
