Do throuples sleep in the same bed?
There is no rule. Three people in a relationship sleep however the three of them agree to — one shared bed, a rotation, a pair sharing while the third has their own room, or three beds. It is a practical decision like any other shared-living question: bed size, snoring, work schedules and whether children or guests are around usually decide it.

The question usually comes from the image of a throuple as three people in one bed, which makes people ask whether that is required. It is not. Sleeping is logistics, and like every other arrangement a throuple makes — where everyone lives, what the calendar looks like, who sleeps where — it is decided by the people in it rather than by the shape of the relationship.
In practice the deciding factors are ordinary. Bed size is the first constraint: a bed that holds two adults comfortably can still leave a third on the edge. Snoring, different bedtimes and different wake times all get worse with company, and a bad night’s sleep is a poor foundation for the rest of the relationship. The options are straightforward — everyone in one bed, a rotation where two share while the third takes another bed, or separate rooms — and the arrangement that works is the one that leaves all three rested, not the one that looks most like the picture.
It helps to separate two questions that get tangled together. Sharing a bed is not the same as being intimate: a throuple can share a bed and simply go to sleep, or sleep apart and have an active relationship. Sleeping apart is not a sign that something is wrong — people of every relationship shape sleep in separate rooms for snoring, shift work, night feeds or plain comfort. And being asleep is not consent: someone who is asleep cannot agree to anything, so throuples tend to have their own norms about waking a partner, and the same consent rules that apply in the evening apply overnight.
The arrangement also has to survive ordinary life. A hotel room with one bed, a visit from family, children in the house, a guest staying over, a night when one person is ill — each of those changes who sleeps where, and the households that handle it best treat those as temporary changes rather than statements about the relationship. No arrangement has to be permanent; as beds, homes, work and children change, the sensible thing is to change with them.
If you are deciding this as a three, the useful test is the one you would apply to any shared-living question: try it, say honestly how you slept, and change what is not working rather than enduring it for the symbolism. The answer on what a throuple is covers the relationship itself, and the sleeping arrangement does not change what the relationship is.
