Buy it! Couch saver
Simple and effective. Zero complaints about the comfort of my couch now. I can't believe I was considering a new $1,500.00 couch a for broken-in couch cushion. Bought one for a friend with the same complaint, and they love it too.

Comfy but way overpriced
These worked to make my couch a bit better but I thought they were much larger. I need 1.5 for one cushion on my couch so one $80 package only did about 3/4 of my couch. Now I need about one more cushion but I ain’t gonna pay $80 for them. They do make you feel as if you’re leaning forward a bit, probably due to the curve in the cushion. I found this worked better when I pulled the foam forward a bit more but it was still a bit of an issue. I wish I could get one more for a lower price. I also wish I could just get an uncurved one since my couch is uneven so I’d like to boost the lower cushions. But lordy the price. Just find bulk foam y’all.

Three cushions fit perfectly
I have a 20 year old “apartment-size” Boston Interiors sofa with 2 rectangular seat cushions. The couch is in good condition except that the seat cushions needed a boost in height. I purchased the 3 firm grey foam cushions, although I was concerned about the fit, based on other reviews. To my surprise, all 3 cushions placed side-by-side fit perfectly to the exact size of the inner sofa. It does not matter that there are 3 square cushions beneath the 2 rectangular ones. They are butted together with no gaps and are not visible under the seat cushions. The couch feels comfortable — the way it used to feel when new. Happy with purchase.

Size
Too small, but is not available for large wide sofas. The cushions did feel as if they would be comfortable and firm, but since the size was to small we could not try at all.

Works Like A Charm
Our old couch is sagging. My 88 year old mom was having trouble getting up from it even more than usual. Did some research, bought this. She loves it. It helps tremendously. Off to shop for a new couch.

Just No!
Just no. Didn’t sit right in the cushions. I should have known and yet I spent way too much money for a product that clearly is a cheaper buy.

Prolonged the cushion life, but...
They did a great job adding life to the original cushions. However, in the months since purchasing the supports and the cushions slide around a lot. This requires quickly adjusting them almost daily.
