They work great. Save yourself some money from buying a whole new couch
I am not being dramatic when I say I was ready to buy a new couch. These inserts are great. I have a VERY old couch so I used 2 in the center cushion and one on the other side that is most often used and sitting on it now I really feel like I could have went without buying a new couch. Oh well. I will keep the inserts and use them for extra support under the new couch anyway

Couch cushion support!
Did not like the feeling of the cushions after putting them underneath the couch. It feels like it’s lumpy. Very uncomfortable to sit on so I removed them. Would rather buy a new couch than use these. I don’t recommend them to anyone.

Don’t buy
It. Square piece of foam. There is no curve to it at all and it offers no support! Save yourself 16.00 bucks and go to a craft store and buy a piece of foam.

Cushion support Worth every penny
Good support Well made. Cushion eliminates the need to buy a new couch or chair. Very nice.

available and fast delivery.
great for the price. added support to older couch cushions but lifts the cushion and can be seen. I also ended up putting a piece of 3/8 plywood under these cushions. Hope to get a bit more life from the old set.
