Because 7 of the 9 sources checked for this guide instruct sleeping with your head or upper body elevated, most often citing swelling or bleeding control as the reason.
Bekweim Adjustable-Height Bed Wedge Pillow, 12 Inch
A steady incline for a few nights' sleep — the buy-path if extra pillows or a borrowed recliner don't work for your setup.
- University of Mississippi Medical Center: "Sleep with your head slightly elevated for 2-3 days."
- Dartmouth-Hitchcock, independently: "Try to keep your head elevated during sleep for at least 3 days after surgery. Sleeping on 2 or more pillows is effective. A recliner chair is an excellent option."
- Mass Eye and Ear, Cleveland Clinic, UNC, MedlinePlus/NIH, and Alberta Health Services all independently instruct the same thing — 7 of 9 sources we read, more agreement than this guide found on any other single instruction.
How we chose it: Built for shoulder-surgery recovery, not marketed for septoplasty — the mechanism is different (swelling/bleeding control here, not shoulder protection there) but the form is identical: a steady torso-and-head incline for sleeping on your back, the same shape two of this guide's own sources describe a recliner substituting for.
One flaw (not a dealbreaker): Two of this guide's own sources name a recliner or 2-3 stacked pillows as an equally valid free option — buy this only if neither works in your bedroom.
