My group chat has forty three messages in it from a single Tuesday night, all sparked by one photo. A friend posted herself in bed wearing a lace up underbust corset, captioned “sleep is better in structure apparently,” and the chat split in half within about six minutes. Half the group treated it like she’d announced she was sleeping in a seatbelt. The other half wanted a link to buy one immediately. Nobody agreed on a single thing, not the safety of it, not whether it looked comfortable, not even whether “sleeping in a corset” meant the same garment to all of us, because it turns out we were picturing at least three different items and arguing past each other the entire time.
I sat there reading it thinking about every corset I’ve owned since roughly 1994, which is more than I’d like to admit out loud, and I still couldn’t land on a firm answer fast enough to type into the chat.

That should tell you something. If someone who’s worn the things through several decades of them cycling in and out of fashion can’t give you a clean yes or no in real time, the question probably deserves more than a group chat can hold.
The corset you’re picturing is probably not the corset that matters here
Here’s where most of the argument in my group chat actually went wrong, and where I think it goes wrong for anyone typing this question into a search bar at eleven at night. There isn’t one corset. There’s a rigid, steel boned, heavily reduction focused piece built to cinch a waist down several inches, and there’s a soft, lightly boned bustier style top that just happens to share the name and the silhouette without doing anything close to the same job on your body. Sleeping in the first one is a genuinely different proposition from sleeping in the second, and treating them as interchangeable is how you end up with forty three unread messages and zero consensus.
I’d like to have a word with the version of me who, sometime in my late twenties, fell asleep in a proper steel boned corset because I was too tired and too stubborn to unlace it after a long night out. I woke up with lines pressed into my ribs that took the better part of a day to fade, and a genuinely uncomfortable pins and needles feeling down one side that I now understand was circulation being cranky about the whole arrangement. That garment was doing its job exactly as designed, which was reduction and shape while upright and moving, not eight hours of unconscious stillness. Nothing about it was built with sleep in mind, and my ribs let me know that in no uncertain terms.
The lighter version is a different conversation, and honestly the one most people mean when they ask the question, even if they don’t know to specify it. A soft cup bustier with light plastic boning, no lacing pulling anything inward, worn more for the shape of the neckline or the support than for any cinching effect, behaves closer to a firm bra than to a corset in the historical sense.

That’s the category where I think the real debate lives, and it’s the one my group chat kept accidentally skipping past in favor of arguing about the extreme version instead.
What I actually think, after testing this on myself more times than I planned to
My honest answer, and I say this after wearing three different corsets to bed over about two weeks purely so I could stop being wishy washy in that group chat, is that it depends entirely on whether the garment is doing any actual work while you’re unconscious. If there’s meaningful compression happening, anything designed to pull your waist in and hold it there against resistance, I don’t think eight hours of stillness is the right environment for it. Your body needs to move, shift position, breathe deeply without resistance, and do all the quiet overnight maintenance that happens while you’re asleep, and a garment built to restrict movement is working against every part of that.
If what you’re actually wearing is a soft, lightly structured bustier with no serious boning and no lacing doing real cinching, worn because you like the shape or the support and not because you’re trying to reduce anything, I think you’re closer to fine than the alarmed half of my group chat wanted to admit. It’s not that different from sleeping in a supportive bra, which plenty of people already do without a second thought.
My sister took one look at the corset in question when I mentioned this whole debate to her and said “why would you sleep in something with hooks in it,” which from her is less a question and more a complete dismissal of the entire concept, and I laughed because she’s not wrong that comfort should be the baseline test here, not a secondary concern you talk yourself past because the garment looked good in a photo.
So no clean verdict, because there isn’t one. Ask what the corset is actually built to do to your body, and sleep in the version that doesn’t fight you for eight hours straight.
