Looking at buidling a DIY memory foam mattress and in case everything goes bad - how easy is it to return memory foam and base foam? Both physcially packing it up and dealing FBM on the phone to do a return..... They do charge a 25% return fee correct?      thanks!

ok I think I was confused on the restocking fee. I guess it is only charged if you do a return in person, not shipped?
