## Description

Bolster Roll Pillow for Sleeping on Back/Under Knees to Relief Lower Back Pain or Between Legs for Side Sleepers Cylinder Pillow with Removable Cover 18x6

Review: My old, lower-back - If you are like me, and need lower back support, this is the last pillow you will ever buy! I suffer from back problems when I’m sitting too long or driving in my truck. This pillow is very firm and does not lose its shape. It’s soft and will accommodate your lower back when sitting on the couch, or even in your truck! I highly recommend it. The quality of the material is very good. It is not made cheaply at all. Also, the lining will zip out and you can throw it in the wash if you spilled Coffee on it or anything like that. I bought other pillows in the past, and this is the last pillow I will ever buy! Thank you for making such a great pillow! It’s worth the money!
Review: Great pillow! - I use it under my knees nightly to takes pressure off my back. Works great. Comfortable, too.

- Sleeping on Side - This bolster roll pillow can also be used as a side pillow to put between the knees for side sleepers to relieve hip or back pain or simply to improve your sleeping posture

### ⭐⭐⭐⭐⭐ good size and texture
*by A***R on November 23, 2025*

I got this for my husband and he loves it for sleeping supporting knees and back. It's filled with pieces of foam, which makes it a little lumpy, but it's so form it doesn't matter.
