Nice surprise, this item holds up well

My mother's couch was sagging in the middle, but she still liked the couch so we purchased this Shinnwa Couch Cushion Support for her about 4 months ago. I asked her how it was holding up the other day and she said it is working out great! She put the support under the middle cushion on her couch so you can't see it and now she can sit on the couch with firm support. Honestly I was expecting her to say that after 4 months it was flat and didn't hold up, but gladly that was not the case. She said it was the right choice for extending the life of her couch. The item arrived quickly and was well packaged.

If you would like to extend the life of a sofa this is the product for you.. my sofa if left as I had purchased had soft seats meaning I usually place more foam in the covers too o keep them plump..but these are a firmer foam that doesn't lose its shape when you sit producing a firmer seat .not hard but firm..you can actually sleep very ..I won't have to buy another sofa for several years..no sliding, pillows stay in place..it's actually a great product and I recommend..

good for back support

the two foam sheets are working out well as back cushions on my sofa to firmly support my back. the slight curvature is very helpful for back support. i was surprised that they were bare foam, but i will put a pillow case over them.
