# About The Side Sleeper

Straight answers for people who sleep on their side, starting with the pillow between your knees.

**Written by Nell, the Side Sleeper**  
For side sleepers whose hips and back complain by morning.

## Why this site exists

Search for a knee pillow and you get ten "best of" lists that repeat each other, and listings that leave out the one number that matters most: how far apart the pillow holds your knees. This site puts the 25 best sellers side by side, explains what to look for, and keeps it short enough to read after a bad night.

## What you'll find here

### Plain guides

What a knee pillow does, how thick it should be, how to use it, and what to change when it hurts.

### One honest table

Every spec labelled with where it came from, including the listings that contradict themselves.

### Sources you can check

Health background links to the NHS and published research, not to opinions.

## The small print

This site is general information, not medical advice. If pain keeps you awake, see a doctor or physiotherapist. Product links are plain links, and the site earns nothing from them. If that ever changes, every page with such links will say so at the top.
