My boyfriend and I made plans and his mom swooped in again?

When we first started dating my boyfriend and I had plans together to update his room, get a double bed, paint the walls etc. One day he came back from work and his mom had repainted the bedroom and brought furniture he didn't ask for. He pays rent and thought it was only fair that he could design his own room.

Now a couple months down the line and the double bed he got was second hand and is so shaky, creaky and broken it's unusable. So me and my boyfriend made plans to get a new bed, we were going to order it so I'm it would come next day delivery. He told his mom and then she swooped in told him it was a bad place to get beds from and insists that she'll pay for the bed from the place she chooses. I trust her experience but at the same time we painstakingly read hundreds of reviews, went and tested the beds etc.

The thing is, my boyfriend has decided not to go through with our plans. That means no new bed for at least a week. What should I do? What should my boyfriend have done?
