Who should buy which

Pick the Kanuda USA Primo Air if

A back or side sleeper choosing between Kanuda's four full size models who wants the range's tallest back-of-head support at 0.98 inches, and who is fine with a pillow the brand itself describes as firmer than a traditional one.

Skip if

The 60 day window is not a free trial: a return or exchange costs $25 per order, the item must go back in original packaging, the policy covers the contiguous US only with Hawaii, Alaska and everywhere else paying return shipping and receiving no refund on original shipping, and the support page calls it a 60-Night Trial while the policy page calls it a 60 day return or exchange window carrying that fee. The one year warranty is scoped to pillows and the in-box pillow cover and never names the four Nap traction devices, the Lumbar Support Back Cushion, the Travel Pillow or the three separately sold pillowcase lines, disputes go to binding arbitration under AAA Commercial Arbitration Rules in Los Angeles before three arbitrators, and Magnuson Moss Warranty Act Title I claims must be arbitrated first.

Pick the MedCline Shoulder Relief System, Small/Medium and Large if

Side sleepers who want a raised wedge, a pocket for the lower arm and a long body pillow in one matched set, who can give it half of a queen bed, and who will give it at least 30 nights before deciding on a return.

Skip if

You want the wedge without the body pillow, which MedCline does not sell; you need a published weight limit or foam firmness before buying; you want a return you can start after a night or two; or MedCline's own warnings fit you, since its product page says not to use the system with a history of heart disease or if substantially overweight, not for infants or children, and that it is not recommended for lower back or hip injuries.
