A very common - almost weekly occurrence is someone asking me to get a replacement part for their older recliner, a set of replacement core cushions or want a matching ottoman to a chair they're had for a while, or even just need to order the right leather cleaning product. When I ask them what they have, its usually "I don't know or I forgot". Without knowing the build, its extremely difficult if not impossible to get those items.

So here's an idea. take either the original receipt - or a photocopy of it - and put it in a ziplock baggie and either tape it to the bottom of your piece or stuff it inside a cushion. That way you will have the order spec down the road if and when you need it.
