Moving into my first studio apartment, I need advice on how to find cheap furniture & home essentials

I'm moving into a studio apartment that's 600 sq feet. I'm looking to start off buying a queen sized mattress, bed frame, comforter set, and a TV/TV stand for the bedroom/living area.

For the kitchen, I'm just getting 2 nook chairs for the nook.

And for the bathroom, I'd like a cute bath mat and shower curtains.

I'm mainly concerned with frugality. Quality matters too of course but I'm not too picky. It's my first apartment after all.
