We have two sofas that have seen better days but don't have the budget to replace them at the moment. Kids who land rather than sit on them, plus a big heavy dog, have meant they are now sagging in the middle.
Google keeps showing me sofa rejuvenator boards on Amazon - are they worth it? They seem to either be suspiciously cheap, or closer to £70 with not much in the middle.
I'd be happy to buy the £70 ones if I knew they were any good, but don't want to blow £140 for both sofas on something that will be useless.
Anyone tried these before?
