A wooden spring includes a strip of wood of medium thickness a, medium width b, and stretched length l. The coils of strips of wood are made using a method of making wooden springs with a helical shape, the coils having a mean diameter d and an average pitch s. Medium thickness a is 0.2 to 2 millimeters (mm), medium width b is 1 to 10 mm, stretched length l is 10 to 5000 mm, mean diameter d is 6 to 60 mm, and average pitch s is 4 to 40 mm. A wooden fabric interlaced of wooden springs includes helix shaped strips of wood. The wooden springs are interlaced with at least two side by side wooden springs to form a wooden spring fabric.

Described are wooden coil springs, including those made of non-compressed wood, and mattresses with such coil springs. Also described is a method of producing a coil spring made of non-compressed wood, which includes winding a slat on reel, steaming and drying to produce the wooden coil spring. Such a coil spring may have a cylindrical shape, a cone shape or a truncated cone shape, and may have a substantially perpendicular end turn with respect to the longitudinal axis of the coil spring.

An exemplary suspension member for a reciprocating conveyor has a horizontally oriented resilient spring member, two bases, and a support. The spring member has a main body, two ends, and a center with a mounting portion. Each base has a retention portion for retaining an end of the spring member. The support supports a tray disposed on top of the mounting portion and has at least one support member extending downward to engage the mounting portion.
