GIONAR 3PCS 50 x 50cm Sofa Cushion Support for Sagging Seat-Sofa Support Boards-Repair Foam- High-Density Sag Repair Replacement for Loveseat Chair balck

Good idea strong sponge gave great support on soft my mum asked for some for hers

I was concerned they would not lift the settee cushions and not offer enough support. They did to some extent. I've got feather filled cushions so they are heavier. But I would consider using a double layer if cushions are heavier. With lighter polyfilled cushions these would be totally fine

Great thickness once unwrapped and fit perfectly

Good quality very comfortable on couch

I bought this to give a bit of oomph to my sofa as the seat cushions had started to sag a bit but it doesn’t really do much good to be honest! The foam is too soft and too small for my needs but it was definitely worth a shot! I now know I need to do something more radical to fix my sagging sofa seat which will involve more invasive measures! It wasn’t that expensive so I’m not too concerned that it didn’t work but it might help some sofas with very minor problems !

Don’t be fooled, these do not make an inch if difference to sofa comfort, maybe if you stack 10 on top of each other but not 1 alone.

I found that they didn't make much difference as they deflated.

These items work well on the couch it's like new
