Gray isnt going to help your bedroom, feel a bit more exciting. It will just add to the blah, you seem to be feeling. Beige chair with gray walls, isnt a good look either. You are mixing warm and cool colors, and not successfully.

Please post some pictures of your rooms, or you wont get much help here. We need to be able to see the space, to advise you.

Based on your description, I created a couple of inspo rooms for your bedroom using Ai.

I designed these living rooms for you for ideas. You seem to like neutrals.
