How do I get a hold of Customer Service for items that were left while checking out?

There is probably a phone number, but if you go to the store, the customer service desk is on the ground floor past the registers.

Call their toll free number

IKEA customer service 1-888-434-4532. Let them know which store location and they should be able to help. Good luck!

Sarah M is correct. There is a customer service number, and we found them to be very helpful. Otherwise, the store will help you all it can, if you feel inclined to go back there.
