An arm support including a mounting bracket configured to mount the arm support to a supporting structure, a track supported by the mounting bracket, a forearm support configured to support a forearm of a user, a linear bearing allowing a first degree of freedom of movement for the forearm support, a rotary bearing allowing a second degree of freedom of movement for the forearm support, and a gimbal joint allowing a third degree of freedom of movement for the forearm support.

The present invention is directed toward a tattoo rest apparatus in the form of a bolster which is adapted for use individually upon a surface such as a table-top, interconnection to a structure such as a seat-back of a chair through wherein clamping elements are used to secure the tattoo rest apparatus to the structure. Alternately, the tattoo rest apparatus can be used in conjunction with a stand, such as a roller-stand with the roller removed, wherein tabs of the stand are inserted through apertures adapted for interconnecting with the stand.

A chair capable of installing a handle freely, comprising: a chair frame formed by two symmetrical sub-frame; each sub-frame including a supporting bar and an assembly bar bending from the supporting bar; one end of the assembly being formed with a hollow space for being inserted by a handle; a seat supported by the chair frame and installed between the two sub-frame. Each chair back has two sleeves at two sides thereof; each sleeve enclosing a respective one of the assembly bars; and a retainer for fixing the sleeve to the assembly bar of the frame. The chair further comprises at least one rotatable handle; for each chair frame, a shaft being inserted into a hollow space of the assembly bar of the frame; and a pivotal device is used to pivotally install the handle and the shaft, and a supporting plate is installed on the shaft.

A stadium chair has a seat frame and a backrest frame pivotally coupled to the seat frame for rotation about an axis parallel to a rear portion of the seat frame. The backrest frame is capable of forward rotation about the axis toward the seat frame and rearward rotation about the axis away from the seat frame. A biasing element coupled to either the seat frame or the backrest frame causes forward biasing of the backrest frame toward a neutral position relative to the seat frame. The biasing element allows for limited rearward rotation of the backrest frame from the neutral position and allows for forward rotation of the backrest frame from the neutral position. The chair preferably is configured to receive optional rotatable armrests that may be installed or removed without the use of tools.

A chair, in particular an office chair, has a backrest which is coupled to a seat support by way of a backrest support. The chair further has a seat face. For tool-free chair assembly the backrest support is constructed in two pieces having a first support member which is associated with the seat support and having a second support member which is associated with the backrest and which is joined to the seat-support-side first support member in a positive-locking plug type connection and is locked therein.

A cushion for releaseably engaging an armrest, said cushion having a top portion, a padded portion, a bottom portion, and an attachment means configured to releaseably engage the cushion to an armrest, where said armrest comprises a top portion, where said attachment means comprises a hook member and a loop member, where the hook member of the attachment means engages the cushion and the loop member of the attachment means engages the armrest.
