Do you think they could make wheelchairs more available at the front entrance or maybe a door greeter to help?

These questions are answered by customers not by Ikea or its employees for these types of questions you should be calling them or posting to their website not on Google- we are the same as you. Good luck working with them to make Ikea more accessible.

They may be able to greet you with one if you call? IDK what they offer in terms of walking assistance
