Sags are deepest at the center, like a crater, which is why Curve is designed with a gradual slope to lift the sag from underneath. Just lift the cushion up and plop a Curve down under it. DONE.
We are the original inventors of Curve, and we make our product 100% IN THE USA from high quality U.S.-fabricated foam.
With Curve, you won’t feel hard wood or plastic when you sit, like you can with other solid substrate sag repair products. Curve’s foam is not noisy either, like chipboard or plastic that can crack or creak.
Curve is naturally slip resistant, too, so it stays put. And you can TUCK Curve into the back crease of you furniture or even TRIM IT if you need a customized size so it doesn’t show under your cushion. One Curve is recommended under each sagging area; furniture pieces with multiple sagging areas may require more than one Curve. Curve will also work on RV or patio furniture that has removable seat cushions. (Outdoor use recommended only in covered areas.) Curve can be spot cleaned and air dried for easy maintenance

Did not bring sofa sturdiness back to new at all. Not happy. I made 2 orders 1 for chair and set of 3 for sofa. NOT HAPPY.

So glad i found these cushions to give my couch a lift! They support well & are helping my back. Easy to use & give an old couch a second chance. Just put them in place under the couch cushions & enjoy the comfortable support.

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.

These worked on my curved couch to make the sagging center less noticeable. I also tried the folding plywood boards and they did not work at all so I returned those and just used the curve cushions.

These cushions are not as firm as I expected them to be. Also, they are quite a bit smaller than our sofa cushions, so I recommend paying more attention than I did to what the cushion size vs your actual sofa cushion size is. I have bought firmer, similar cushions that provide more support than these. That said, I did like the contoured shape of these cushions. I don't know yet about the durability because we've only used them a couple of weeks.

I recieved these cushions on Sunday and installed them. Seem okay, but had to say how they are going to work after 1 day. Ask back in a month or so.

Comfy and undeniable difference made. From a droopy couch that hurt my back to a well-supported and ideal experience. Great buy!
