The right pillow can play a huge role in getting a good night’s rest. For side sleepers, knee and body pillows can keep the spine aligned and relieve pressure around the hips and knees. I tried the Coop Adjustable Knee Pillow which is 20% off for Presidents’ Day, and I was amazed at how much my sleep improved. It's now $36 (was $45,) and I think that's a great price to achieve better sleep quality.

Like some of this year's best pillows for all sleepers, this knee pillow from Coop is fully adjustable which means you can change the firmness level and loft according to your sleeping preferences and body type. Because of this, side sleepers can enjoy the perfect loft to keep the spine aligned throughout the night. Personally, I've found my back pain has alleviated since using the pillow, and I stopped tossing and turning, allowing me to get deeper, more restful sleep, which is why I think the right pillow is just as important as investing in the best mattress for your needs.

Summary: The first thing which struck me about the Coop Knee Pillow is its ergonomic hourglass design which conforms to the shape of your knees. It is made from four CertiPUR-US certified memory foam blocks in varying thickness which, like the best mattresses for side sleepers, instantly relieves pressure from your knees, hip and spine, the major pressure points while lying on your side. You can adjust the firmness to suit your preferences by simply removing the foam inserts. This helped alleviate my backpain symptoms as it prevented me from sleeping in a position that put pressure on my spine, helping me maintain proper alignment. It comes in a breathable Lulltra (a blend of bamboo-derived viscose rayon and polyester) cover, so you don't have to worry about overheating either. The Coop Adjustable Knee Pillow is now 20% off for President's Day which drops the price from $45 to £36.

Price history: The lowest price we've seen for a Coop Knee Pillow during major sale events like Black Friday and Memorial Day is $40, which means this is the best deal we've seen so far and one well worth taking advantage of.

Benefits: 100-night sleep trial | 5-year warranty | Fast shipping
