Made from a high-density foam material, this set features four different ergonomically designed wedge pillows that can be arranged in countless ways to accommodate whatever lounging or sleep position you happen to be in. This includes an elongated pillow that can be added to the neck, back or arms.

Whether you need leg elevation, lumbar support, or back support, the pillows can help keep you aligned. The main back pillow can even be angled more horizontally to keep you supported in more conventional supine sleep positions.

The pillow’s covers, which are removable and machine-washable, are made from a soft fleece material that also features helpful anti-slip points, so that once your pillows are arranged exactly the way you want them, they stay there.

Reviewers say this pillow set has come in clutch for post-surgery healing, pregnancy, reading in bed, or for anyone who suffers from chronic back pain. According to previous interviews with gastroenterologists, sleeping with certain wedge pillows may even help with conditions like acid reflux, snoring, sleep apnea and nasal congestion.

“I’ve noticed a significant reduction in back and neck pain since I started using it,” one Amazon customer enthused.
