When two people attempt to lean against each other to
sleep, it presents problems, particularly when their heights
The CTPUS is an elongated, flattened pillow, about half a
metre long, and about 15 cm wide. It has three hinges,
about 10 cm apart, at the centre. The hinges have
locking system, where a button or twist-lock mechanism
projects along the axis of rotation, through the short side
of the pillow.
The pillow can be used in three ways:
(1) For two people of similar heights, it can be formed into
a kite, with the short sides resting on their shoulders, and
their heads resting on the long ones.
(2) For two people of dissimilar heights, it can be
zigzagged over the shorter person's head, then the taller
person's shoulder, then the shorter person's shoulder.
(3) For one person, it can be used in a large triangular
form, as with (1), or with two segments making half a
wedge, and the other two going straight down, to provide
cushioning against a wall or bulkhead.
