US Patent 12011383 Apparatus and methods for maintaining a side-sleeping position

A limb restraint includes a flexible limb sleeve and a strap. The limb sleeve permits a sleeper to insert or remove a limb into or out of the sleeve, intentionally while awake, yet inhibits unintentional removal of the limb from the sleeve by the sleeper while sleeping. The strap connects the limb sleeve to a mattress or bedframe so that the limb sleeve is in front of the sleeper while in a side-sleeping position, and with an upward-side limb of the sleeper inserted into the limb sleeve, so that the limb restraint maintains the sleeper in the side-sleeping position while asleep.
