Get it appraised and give them the appraisal. They will need it anyway for insurance purposes.
The problem though is that they may not use it because they are afraid of wrecking it. I get it that you don't want them to use it for the dog's bed (been there, done that). I agree with the other poster though. When you gift it, it is theirs. Another poster had a great idea - let them know that if it is not to their taste, to please give it back to you and you can talk with them about making something more appropriate to their taste.
