If you often struggle to sleep upright in a chair, the Trtl Pillow Plus is worth a look. Its adjustable front and zero padding at the back keep your head against the seat — a big step up from airport pillows. You can grab one for $62.99, and delivery is $3.99 unless you spend $95 or more for free shipping. The deal runs until 10:30pm, so don't wait too long.
