I have owned a few of these and my old one finally just gave out over the years. when i saw this one I thought why not give it a shot its the same shape and size and i was not disapointed. I love this coushion its similar to memory foam as it molds nicely and fees confortable to sit on. the size fits the chair perfectly and the feel of the fabrick is nice. All in all i love this coushion and will more than likely be buying more. If anything changes i will update this post till than have a great day.
