My original patio chair cushions were the typical 3 inch foam rubber which made sitting out doors uncomfortable for our legs and back. In addition, trying to get out of the chair was at times a real chore due to reduced circulation. We love these seat covers! No longer do our legs nor back suffer. My only problem is I ordered just two. I will be ordering two more in the near future. Love them! They are well worth the funds spent. Thank you Wayfair for having higher quality merchandise at an affordable price!!
