I'm moving soon, and noticed that standard North American bedding feels super overkill in some situations.

I was thinking about putting a fitted sheet atop my mattress, and buying a heavy blanket to sleep under. No top sheet, no comforter, no duvet. My space has great temperature control, so no worries about heat fluctuations.

Does anyone practice something similar? Not sure if I'll be missing out on anything by not going the traditional bedding route.

Here's what I'm thinking: https://i.imgur.com/VH8LamW.png

In my experience, I've used a topsheet and what I think is a comforter (big, fluffy, rectangular, hangs off bed but doesn't reach floor). I've also just used a comforter by itself. Either way the comforter covers my body and keeps me warm. And then blankets (thinner/smaller) on top for added warmth. And my understanding is that you don't put anything else on top of a comforter.

In hotels/motels, there's (what my mom referred to as) a bedspread (thinner than comforter but touches the floor, outlines the pillows and looks pretty) and under that is a blanket(?) and then a topsheet (or vice versa? It's been a minute.). But online I'm seeing them referred to as a coverlet? My mom said to NEVER use the bedspread as a blanket/comforter for sanitary reasons (like they aren't washed as often and people sit and lay on top of them before going to bed?), so I just use the top sheet and blanket to cover me.

I also always thought quilts were just blankets made with smaller patches stitched together in a pattern. Is that correct? Are they used interchangeably with blankets?

And then what even is a duvet? I thought that was just a British English for comforter?

What things go with what and where and what am I supposed to do with them? I'm just trying to sleep!
