The idea is to create a bed that detects bad posture and gently moves you into optimal positions without disturbing your sleep.

Bad posture during sleeping obstructs breathing, compresses the vital organs and (hypothetically) over time worsens our overall posture.

A bed that reshapes

The entire cushion surface of the bed is lined with retractable padded bollards. They make it possible for the contour to reshape in any way need. That gives it the ability to gently provide support, move your limbs or even rotate you. All this goes on so quietly and slowly that you don't feel a thing.

If the bed detects snoring, it gently rotates you until your airways are unobstructed.

If you fall asleep on the side, the bed reshapes so that your spine is straight. This means your shoulder and hip sink down, the rib cage and neck are propped up.


The bed can feel your pulse and breathing rate. If it detects a change while moving you, it momentarily stops until you relax again.

Infra red cameras or even sonar make sure the bed knows your exact position at all times.

This was inspired by Samuel's padded pajamas idea.

In fast interaction mode, the bed would adjust live, as you move. While you are awake it would only try to support you, but not actually move to correct you.

While you are asleep it would gently move you as you move so as to prevent you from even settling in bad positions. This would likely take a few days to get used to - similarly like when people have to get used to sleeping next to someone.

I like this idea more than the padded pajamas because it gets rid of some of the problems I had with those. However, you would need a quite smooth, silent and precise system to be able to move the mattress in a way that does not cause discomfort or wake up the person. You would also need a proper way to detect the posture. I don't think pressure points are enough since you can use the same contact points but have relatively different postures. Also two people sleeping in the same bed could make this extremely hard. Lastly, I imagine this could get relatively expensive and pretty heavy. What do you think?

Posture detecting could be done with infrared cameras or even sonar. It could possibly even be done with machine learning based on detected pressure points and weight.

Small, super silent, slow electric motors with a lot of torque would push the padded rods out of the mattress. They wouldn't bend the entire mattress. Just soft rods would come out in groups to make little hills and valleys in the mattress at precise spots.

Yes, all the electronics would add to the cost. On the other hand, how often do people buy beds? Those that are conscious of their health might find it worth the money. Also, as the bed is iterated from experience we may find that fewer rods are needed to achieve the same results.

Yes, two people sleeping together could be tricky, especially if the necessary maneuver involves rolling one person towards the other:)
