    Bad odor
  

*by B***Y on Reviewed in the United States on July 5, 2019*

The product is well manufactured. I gave a low rating because the stench (odor) emitted from pillow is awful. I have other memory foam items with no odor. I purchased two & they will be returned. Sorry.

### ⭐⭐⭐⭐⭐ 







  
  
    Doesn’t slide off while your seated its perfect plus adds a little more softness to chair.
  

*by P***Z on Reviewed in the United States on May 9, 2019*

looked  everywhere for something that would help me protect my chairs from my lounging cat! She would sleep in my counter chairs and stretch and claw my NEW chairs. This is the perfect thing to help both her and them! Easy to sit in and soft plus it doesn’t slide off while your in it. Someone thought of everything here. Comfy and sleek!

    Great Product - BUT Keep Something in Mind
  

*by L***Y on Reviewed in the United States on July 5, 2019*

This is a great little cushion. Better than any others I have tried. HOWEVER, you WILL bottom out onto the surface below. I bought it for a stool at one of my video editing consoles in my studio. The stool does have a padded seat. But after about 30 minutes, my butt starts getting sore. So I bought this cushion to set on top of the other padded seat of the stool. After about 45-60 minutes my butt starts getting sore. No doubt it's better than sitting on a wood/metal stool. And most of you will not use a stool for long periods of time like I do. But you WILL still bottom out and will eventually feel the hardness from underneath even after a few minutes. So just be forewarned . . . I do love it, but it's NOT the answer to a sore butt if you sit on a stool for any length of time besides having a bite to eat, or a couple cocktails. If you are okay with that, then this is the BEST cushion I have found.
