Description:
the unused half tread becomes
an obstacle, significantly
reducing the usable tread
depth of the tread directly
below. As the angle increases,
the problem becomes worse. LAPEYRE STAIR
In contrast, the Lapeyre
stair removes the unused
half of each tread, allowing
the foot to reach the next
tread in a straight, direct
line, providing more usable
tread depth.
