They came quickly and were exactly what I was looking for. They slid into my couch cushion covers super easily. They do take 72 hours to fully "inflate," and I have not reached that time frame yet but so far I am very pleased!!!. Lee Ann. Crofton, MD. Thu Jun 25 2026

This was perfect! We've got an old but high-quality, solid wood sleeper sofa. It can't take a very thick mattress, so the cushions have always felt a little low, and you can feel the metal bar of the bed frame. Ordered this pad, trimmed it to length and inserted it under the sofa cushions. The pad tucks in and is invisible, and the sofa is at least twice as comfortable as before. It's now appropriate for napping without opening it up. :). Kathleen. Brooklyn, NY. Mon Oct 12 2026

This is a wonderful couch replacement cushion. It comes with a zipper cover in grey as well. It is well constructed and comfortably firm. However, it did not fit my couch.

Although I am sorry it did not fit my sofa, I am happy it is making my dog happy. She loves it. If it will fit your couch or chair, I highly recommend it. It is a quality cushion.. Marykay.
