A seating apparatus may include a seating unit and a pair of hollow supporting structure. In one embodiment, the hollow supporting structure is bowl-shaped springs which can be disposed underneath a seating unit to receive and support the buttocks of the user. In another embodiment, the seating unit can include a regular seat, a stool, a bicycle seat, and even a horse saddle. More specifically, the buttocks of the user can be received in a concave surface of each bowl-shaped spring so a complete support over a large area is provided to the user's buttocks and pubic bone to eliminate the pressure therefrom. Furthermore, the springs can also be used as cushions to absorb impact on the user's lower body portion. In another aspect, the hollow supporting structure is a pair of rings, and in a further aspect, the hollow supporting structure is a pair of bowl-shaped units.

Catalytic enzyme-modified textiles are disclosed for providing protection from chemical exposure. The textiles are composed of a cloth substrate, at least one polyelectrolyte layer, at least one enzyme layer to degrade the chemical agent, and at least one capping layer. Also disclosed is the related method for making catalytic enzyme-modified textiles.

Method for making catalytic enzyme-modified textiles for active protection from toxins

A bioactive catalytic material is disclosed for providing protection from chemical exposure. The material is composed of enzymes immobilized within polyelectrolyte multilayers and a polymerizable end-capping layer to render stability to enzymes. Also disclosed is the related method for making a bioactive catalytic material and their deposition on substrates of varying size, shape and flexibility for providing active protection from chemical exposure.
