A disposable barber-chair headrest protective covering is provided to be used specifically for the headrest of a barber-chair. The disposable barber-chair headrest protective covering will be used to cover the headrest of the barber-chair before each service to prevent the cross-contamination of germs, hair debris, and infectious disease that can be transmitted from the head, scalp, or/and hair. The disposable barber-chair headrest protective covering will also minimize erosion and damage to the barber-chair caused by chemical build-up.

The disposable barber-chair headrest protective covering will be made of material that is disposable, inexpensive, and flexible, with an elastic (or similar) band adhesive or sown in at the edges for flexibility. The elasticity allows the covering to hug the headrest of the barber-chair and be close-fitting. It can be applied by opening the elastic edges of the invention and sliding it onto the barber-chair headrest.

An exercise chair includes a chair frame, and a base fixed with the chair frame that is adapted to support the exercise chair on a floor surface. The base and chair frame have a plurality of anchors projecting away therefrom. A cushion may cover at least a portion of the frame. Multiple resistance bands each have multiple longitudinal slots therethrough, each adapted for selective fixing with any of the anchor knobs or several attachable exercise devices. In use, with the person seated in the chair and the chair resting on the support surface, one or two of the resistance bands can be fixed with any of the anchor knobs, so that the person can exercise by pushing and/or pulling the at least one resistance band. Different types of attachments are included for exercising varying muscle groups.

A chair-type massage machine includes a main body on which a person to be treated is to be seated, a holding part at least part of which is placed inside a container recess to hold a first operation unit, and a moving mechanism for moving the holding part. The holding part is reciprocatably moved between a first position in which the first operation unit is contained in the container recess and a second position in which the first operation unit is exposed. The chair-type massage machine further includes a second operation unit for moving the holding part.

A chair includes a seat support, a leg frame extended underneath the seat support, a back support upwardly extended from the seat support, and a back support guiding arrangement. The back support guiding arrangement includes a guiding wheel rotatably mounted on a rear side of the back support for biasing against an external object so that when the back support of the chair accidentally hits the external object, the guiding wheel is arranged to act as a buffer to minimize damage imparted on the external object.
