Love it, has Velcro so doesn’t shift and when I took it out of vacuum bag thought it wouldn’t be good but after 24 hours puffed up and feels like soft memory foam. Perfect for a chair I have with a lower back. A big thumbs up January 25, 2025: I change this to a 4 star, after using there are white silk like strings coming off the material onto my hair. Not sure why!!!!!!!!

Wish The Adhesive Pad Worked With Leather

Size: Medium, Color: Grey

The pillow is comfortable but the adhesive pad on it needed to be more sticky for leather. I still give five stars because they reached out and offered to help with a full refund, and asked for pictures to help identify the problem.

Made a great pillow better.

Had an awesome pillow but if I didn't fluff it before going to sleep my neck would hurt the next morning. Ordered this and put about 70% into a cardboard box to expand then shoved it into my pillow. Its been great 👍 put the rest in another pillow. Had no scent. My pillows are king sized.

Great for refreshing old memory foam pillows

Our memory foam pillows are 2 years old and need a little refreshing. We purchased this and was able to refresh both pillows to firmer than new condition.
