It is PERFECT for those things. It does squish a bit, but I find that very comfy, and it still offers (for me) the perfect support. The product info states that such is intended--that 8 inches squishes to 5-6 inches, which is recommended and intentional. Those complaining that it isn't firm should read about what they are purchasing, rather than give a low review. I had much rather a soft 5-6 inches of support than a hard piece of dense foam of the same height. The cooling cover is soft and smooth, which is good because it doesn't cling to the sheets--this makes it easy to slide around (unlike a regular pillow) when you want to reposition it at night. I do find that the cover pills, but for me that is not a big deal. It is also easily washable. And it is not sweaty or hot on the skin, even under very warm covers. Love that. It does arrive squashed flat in the packaging, and includes clear directions for fluffing it up in the dryer. Do what it says, and the pillow will poof up just fine. As to customer service: After about 3.5 months, I removed the cover again to wash, and a bunch of the foam fell all over--the closing seam had torn open. I was so sad. I contacted the company, and John at Kingnex was happy to send a replacement--awesome! Truly an easy and great customer care experience, for a great product. Thank you John! If you are a back sleeper, order this pillow, it's soft and comfy knee support so your back will love you. If you are a side sleeper, order this pillow, it's soft under your top knee so your hip will love you. Add a weighted blanket, and it will be the deepest, most comfy sleep of your life. :) Review: Read And Follow All The Directions To Get The Full Benefit Of This Pillow. - I bought this pillow and it arrived all crushed with the external cover unzipped in two spots. I ran the zipper back and forth a few times which re-seated the zipper teeth. On the package insert info, it said to pin close the zippers (internal and external) before putting the pillow in the dryer. I used safety pins to secure both zippers closed. I put the pillow in the dryer for a full 30 minutes on No Heat. It came out looking much like the picture on desertcart. The factory smell I read about was mild and has since dissipated. I used the pillow a few nights and found it to be too heavy for my liking. It weighed about 4 lbs., so I removed 1 pound of filling. (I am storing that extra amount in a plastic bag) I've been using the pillow between my knees to sleep with ever since and I find it helps my hips a lot and I don't move around at night as much as I did before. I love this pillow and I recommend and endorse it. ## Features - Fluffing up Before Use - The pillow arrives vacuum-packed, it might be flat when just taken out. Therefore, it's suggested to put it in the dryer with no heat for 15-30 minuts, or leave it for 24-48 hours to allow it to regain its original shape. - About Size - The pillow measures 18 in long and 6 in in diameter, filled with responsive shredded latex, so the thickness will decrease when putting under knees or between legs, provides balanced support needed - Breathable Cooling Cover - The cover uses cooling nylon which is breathable and is zipper removable washable, the pillow insert cover is zipper sealed, so you can customize the firmness by adding or taking out the latex foam - Sleeping on Back - This cylinder roll pillow can be used under knees to relieve lower back pain, perfect for back sleepers - 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 ## Technical Specifications | Specification | Value | |---------------|-------| | Brand | Kingnex | | Color | Cooling Cover - White | | Fill Material | Latex | | Item Dimensions L x W | 18"L x 6"W | | Item Firmness Description | Firm | | Item Weight | 1.06 kg | | Material Type | Latex | | Pattern | Solid | | Product Care Instructions | Machine Wash | | Shape | Cylindrical | | Size | 18 x 6" | | Special Feature | Adjustable | | Special Features | Adjustable | | Target Use Body Part | Legs | ## Product Details - **Brand:** Kingnex - **Special Feature:** Adjustable - **Color:** Cooling Cover - White - **Size:** 18 x 6" - **Fill Material:** Shredded Latex ## Images ![Kingnex Cylinder Bolster Roll Pillow for Sleeping on Back or Side 18x6 - Image 1](https://m.media-amazon.com/images/I/41f4-tRJPXL.jpg) ![Kingnex Cylinder Bolster Roll Pillow for Sleeping on Back or Side 18x6 - Image 2](https://m.media-amazon.com/images/I/71UEElt2jDL.jpg) ![Kingnex Cylinder Bolster Roll Pillow for Sleeping on Back or Side 18x6 - Image 3](https://m.media-amazon.com/images/I/71OebUcCg3L.jpg) ![Kingnex Cylinder Bolster Roll Pillow for Sleeping on Back or Side 18x6 - Image 4](https://m.media-amazon.com/images/I/61x5Afje0fL.jpg) ![Kingnex Cylinder Bolster Roll Pillow for Sleeping on Back or Side 18x6 - Image 5](https://m.media-amazon.com/images/I/61HQ8g5JnpL.jpg) ## Available Options This product comes in different **Color, Size** options. ## Customer Reviews ### ⭐⭐⭐⭐⭐ great pillow and great customer care *by W***. on February 26, 2021* I ordered this pillow for under my knees at night (back sleeping), as well as for support under the knee when side sleeping.
