Littlesun Premium Comfort Seat Cushion – Non-Slip Orthopedic 100% Memory Foam Coccyx Cushion for Tailbone Pain – Cushion for Office Chair Car Seat – Back Pain & Sciatica Relief (Seat cushion)

This cushion is high density memory foam, thick, and covered with quality materials by the feel. The thickness is good. I don't understand the reason to put a bump at the crotch or the split at the back, but it is still comfortable.I have only just received this cushion to turn my cheap office chair into a comfortable office chair. I will update this review if quality, comfort, or construction should change. As of this first impression, 5 stars!

The product is good but I received the same product with more thick memorable foam inside with the same price.

It helps with back pain

Its probably good for office chairs but It’s too small for car seat, it’s not comfortable

It's good but I can't use it.

It’s definitely better to use this than sitting directly on a plastic or wooden chair. However, it would be nicer to use if you use this with a pillow case as the cloth/ material on the actual pillow is scratchy. Good to note that you need to “puff” this up after an hour since the the foam basically absorbed all the weight and would need to breathe to be comfortable again.

This is not comfortable AT ALL.

Utter waste of money, this cushion isnt sturdy, you just sink into it and ended up hurting my coccyx more.
