Re: new cushions?
If you have Brompton Cocoa then that's normally a Restoration Hardware brand sofa as that's the name of a popular leather they sell. Contact your local store and their customer service department and ask for a set of replacement cores. If that not a RH piece, then contact the seller directly. Quality cores should not wear out in 1 year, or lose their resiliency. You really can't alter them per se, you replace them with new. You can - as an option - have a local upholstery company wrap them for you which will give you more fill . Good luck.
