I had to buy a full bed in 180X200, everything was available except the box spring, the saleswoman confirmed to us that it would be available on Saturday 19 or maximum Tuesday December 22, but that we had to buy the mattress because there were only three left and that they were leaving very quickly!
I bought everything mattress sheets ect 700 euros without the box spring, and without any news, I called him and there they are delaying January 3, so I have a mattress on the floor and without explanation.
their sales method and ashamed, i buy a lot from ikea for myself and my work, i will definitely see my supplier again.
