Review: Good Quality! - After trying several other seat cushions and chair pads that have a defined design for the buttocks but were not that comfortable, I am pleasantly surprised that this big thick square is what feels best! It has a soft velure cover that zips off for cleaning. It's supportive firmness yet a soft give supports my back and allows me to sit comfortably at a desk for several hours. I chose it because I needed to see over the computer monitors at church to best run programs for worship, sermons etc. I am 5'4 and about 135lbs and find that after several months, this cushion still feels new and gives me the physical boost to sit higher than the chair allows. I highly recommend!
Review: Comfortable cushion! - The hydraulic lift on my old office chair was failing so I bought this cushion to add height while working at my desk. The cushion measurements fit perfectly for my chair with arms - so do note the measurements before ordering. My old chair’s cushion has also become hard, so this new cushion adds firm yet soft comfort while sitting for many hours per day. The cushion stays in place and doesn’t move around. It’s extending the life of my office chair as I’m on a tight budget. The affordable cost of this cushion is much less expensive than buying a new chair.

## Features

- VERSATILE COMFORT - Features a stylish quilted design and soft velvety fabric paired with premium memory foam. These thick seat cushions provide consistent support for wooden kitchen chairs, dining chairs, or armchairs, enhancing the seating experience during extended use.

### ⭐⭐⭐⭐ The best FIRM cushion I've found so far.
*by T***R on August 5, 2022*

I bought two of these cushions in black to place on dining chairs because the typical chair cushions with tiebacks simply are not firm enough for sitting on wooden chairs for a long time. They are very comfortable and don't easily slide off the chair due to the rubberized bottom. If you're a short person, you probably will push upon the cushion more since they're taller than the average cushion. On top of these cushions I have placed the tieback-type cushions for more comfort but to also protect the new ones and keep them looking new since they're made of a velvet type of fabric. These cushions could actually be MORE FIRM for my liking, for more comfort and longer life. As is, I think, and hope, these cushions last a year+ since they're not cheap.
