Elevate your low-back legless sofa with this 3-pack ergonomic headrest set, expertly crafted for tall users and featuring a sturdy metal frame with soft corduroy covers. Custom-fit for sofas ≤28.5" in height, it delivers reliable neck/head support, requires only simple assembly for quick setup (no drilling/permanent mods), and is easy to maintain with a damp cloth wipe—ideal for 3-seat, modular and L-shaped couches.

The support head rests worked exactly as I wanted them to. The backing of the couch I got from Wayfair does not support the cushions so, when I would sit down, my head would just fly back into the wall behind me. These headrests provide the perfect buffer to keep the cushions up straight and make the couch comfortable.. Rebecca. Louisville, KY. Thu Mar 19 2026

Shipped compressed in a box, it fully recovers in 48-72 hours for long-lasting daily use—no need to replace old furniture, just refresh it!

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. Before I could think about returning it, my dog claimed it as her own. It is probably the fanciest dog bed she has ever had. 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.

Couch Cushion Supports for Sagging Cushions - Sofa & Couches Seat Saggy Cushion Saver & Lifters, 20x20x2 Couch Supporter for Under The Cushions, 3-Pack, Gray

Stacy, I bought the cushion supports for the new Freda couch and loveseat we just purchased from you. They didn’t help much. I know you offered to take them back and gave me some money but I thought there was something I could do because the couch and loveseat were exactly what I wanted. What I’m asking is please don’t sell them to anyone else. There is something wrong with the fabric. I’ll probably return the couch supports. If you have any other ideas please let me know.
