### ⭐⭐⭐⭐ Did the job!
*by M***H on January 9, 2025*

We purchased a new sofa online about a year and a half ago because we needed one right away. It was expensive, looked very comfortable and got good reviews, so we took a chance. After a month or so it felt like an old saggy sofa, but it was too late to return it. Adding additional pads and pillows hasn't really helped. Although this doesn't completely fill the width of the base it is long enough from end to end and provides just the right amount of support. This cushion support was worth the expense and saved us from having to buy a new sofa!
