## Customer Reviews

### ⭐⭐⭐⭐⭐ Finally getting proper sleep
*by M***. on September 8, 2026*

Wife and I have severe knee issues. Fantastic job from keeping pressure off knee when side sleeping. Actually getting better sleep now because no more pressure

### ⭐⭐⭐⭐⭐ More Versatile Than a Knee Pillow
*by A***X on September 13, 2026*

I’ve been using this pillow for my head, knees, and feet, and it’s comfortable in every position\. It has just the right amount of softness and support, and the washable cover is a convenient bonus for keeping it clean.

### ⭐⭐⭐⭐ Works Well, Missing Certification
*by L***S on May 20, 2026*

Received yesterday. Nicely packaged, plumped up easily, kept my knee raised throughout the night, and plumped back afterwards. The only issue that I have is the following: Product description claims OEKO-TEX Standard 100, but it is not found stamped anywhere on the box or the product, so therefore, not OEKO-TEX, which is important because it bans the intentional use of PFAS; their labels and certificates confirm the safety of textile products from all stages of production. I specifically purchased this bolster pillow because of the positive reviews, and mostly because of the OEKO-TEX certification, which appears to be false.
