  • Made my couch comfortable again.
Color: Soft 1p
Had a big sinkhole on one end the couch. I lifted the cushions put a board on the spot with this pad on it. Worked great. Then I felt the other end felt saggy in comparison so I came back and bought another one and did the same on the other end. Not only is it easier on me with my old knees to get off the couch but I also don’t have to worry about where company sits anymore. They won’t feel like they’re falling thru the floor. ... show more

  • Good quality.
Color: Firm 2p
These are really nice to give somewhat saggy cushions a lift and make them feel firm again. Great value for the cost…a lot less than buying new cushions or a new couch! They fit all sizes and can cave cut down, if needed. All you have to do to “assemble” is open the package and place them under your cushions! So, easy assembly! Once the calm a bit, Yugoslav can’t even see them. ... show more

  • Little lift
Color: Soft 3p
They do add a bit of lift to a sagging couch. A little more thickness would be great but pleased with the purchase.

Simply amazing. Lifted sagging cushion like magic!

  • They work great
Color: Firm 3p
The couch cushion gave the support I needed on my sectional. I had to position them so they would not make the cushion stick up.

  • Not what I expected
Color: Soft 2p
Very thin and not much lift. Too much money for the quality. Next time I will buy pillow filler a the cloth store. Also not comfortable. Would not recommend
