### ⭐⭐⭐⭐⭐ 5.0 out of 5 stars







  
  
    Renewed my sofa!
  

*by N***E on Reviewed in the United States on May 4, 2024*

I actually crammed them into the cushion upholstery.  In the first pic, I hadn’t added the foam to the center cushion.  In the third, all have the foam inserted.  Sofa looks so much better and has much better support.  Foam could be a little more dense, but hopefully will hold up for a while.

### ⭐⭐⭐⭐ 4.0 out of 5 stars







  
  
    nice quality but a little too small on my standard size couch
  

*by D***  on Reviewed in the United States on February 19, 2024*

They work well, but would have worked great had they been just a couple of inches bigger all around with a longer taper.

### ⭐⭐⭐⭐⭐ 5.0 out of 5 stars







  
  
    Fantastic buy
  

*by M***D on Reviewed in the United States on April 23, 2024*

Why didn't I know about this long ago!  These foam cushions are amazing and make my couch like new.  I was days away from just ordering a new couch because I was sinking into the couch. With these, it makes my couch firm and no sinking.  With the foam, it does make the cushions move a bit so I have to adjust them a bit but a small work order to the comfort I now have.  Will buy again and put in storage before inflation gets to them.
