guys, I have bought new home and want to buy some furniture for my bedroom?? What I need to buy first??

A bed, a closet, a nightstand. That's literally all the furniture I have in my bedroom.

I don’t understand why you’re asking here of all places. Just google it.

Yea, this is probably not the most sensible place to ask...
But if you really want input... You'd probably need a dresser, night-stands/end-tables, obviously a bed...
As for the rest of the house, IDK what to tell ya since IDK what you have or want. That's more subjective.

Dude your profile pic is ironic for this thread not gonna lie.
Now with that out of the way to the topic at hand you would also probably want a desk depending where your compter or laptop is kept alot of it depends on your layout

A cage, a miniature dungeon, probably some sort of laboratory with brainwashing equipment would be some good first steps.

What about recliners? I use the power lift recliner. Very convenient thing when you come tired after work. I bought it on the recommendations [redacted by staff]. These chairs have already proven themselves due to the quality and convenience.
