I once had an appointment through Ikea for a few items to be delivered. It took 4 different missed appointments for them to finally deliver it. It was a nightmare. First one they never contacted us when they arrived (I live in an apartment building, no way in for non-tenants). Second one was apparently never put in the system. Same with the third one despite me calling the night before to confirm that everything went through, they even confirmed with the third party delivery service. Fourth time it finally showed up.
Would not recommend.
