Straight answers on warranty and delivery — confirm both in writing before you pay.
Ask for the warranty terms on your specific piece in writing before you pay. A verbal promise on its own isn't something you can hold anyone to later.
Get your delivery date confirmed in writing before you order, especially for larger pieces like beds, wardrobes and sofa sets.
See and touch the actual piece in the showroom — fabric, finish and build quality — before you commit.
Keep your receipt and any warranty document safe after you buy — you'll need both if you ever need to make a claim.
