Or are the cheaper ones just as good as the more expensive ones?
I have bought myself a lovely new mattress from Groupon but DS sleeps in my bed most nights and on a rare occasion he will have an accident. I need to buy a waterproof bedsheet but not sure if the expensive ones are worth it or a cheaper one will do just as well.
Also, is there somewhere I can donate my old mattress to? It's not suitable for humans sleeping on as the springs are broken and it is stained from previous accidents. But maybe there is somewhere like a dog shelter that could use it? Or is that silly?
