The NeckPillow by Tempur-Pedic™ is recommended for those who desire not only a better night’s sleep but also need a more therapeutic sleep posture. The dual-lobe design supports the curve created by your head, neck and shoulders to properly align your spine and give you a perfect night’s sleep! It is important that you choose the proper pillow thickness based on your shoulder dimensions and sleeping position preference to promote an anatomically correct posture. A pillow that forces your head too high or allows it to fall too far back not only places stress on your neck, but could inhibit breathing. Pillows are non-returnable and do not have a tryout period.
