A buoyant pool lounge chair frame and buoyant pool lounge chair using the same are disclosed. In one embodiment of the buoyant pool lounge chair for supporting a person while the buoyant pool chair is floating in water, frame members collectively form an open chair frame including a back frame and leg frame pivotally coupled thereto. Buoyant cushions are attached to the frame members to form a chair seat, a backrest, and a leg rest. A pair of rear pivotal coupling and clutch assemblies are coupled to the seat frame and to the back frame to adjust and fix the angle of recline of the back frame relative to the seat frame. Similarly, a pair of front pivotal coupling and clutch assemblies coupled to the leg frame and to the back frame to adjust and fix the angle of extension of the leg frame relative to the seat frame.

Methods for a cell-based assay for Botulinum neurotoxin are provided in which a transfected cell that produces a reporting peptide is contacted with a Botulinum neurotoxin in media having a sub-physiological osmolarity and a temperature that is above physiological temperature. This combination provides an unexpected synergistic effect in reducing the EC.sub.50 of the cell-based assay relative to an analogous cell-based assay performed at physiological osmolarity and temperature.

Light weight, easily stowed in small spaces inflatable chairs, pads, and flotation devices all from a relatively simple combination of at least two inflatable drop stitch panels which can be held in position relative to each other by use of straps, or in other embodiments, by additional inflatable side panels which provide arms and support to hold the chair upright on the ground. Simple hinges can be used to connect the panels together in desired configurations, either as fixed deployments or as adjustable and convertible deployments, where in one deployment, the panels for a chair, and in another, a flat pad, which can be used as a float or as a ground pad for camping.

A buoyant pool lounge chair is disclosed. In one embodiment of the buoyant pool lounge chair, frame members collectively form an open chair frame with buoyant cushions forming a chair seat and a backrest as well as a left arm rest and a right arm rest. The left arm rest and the right arm rest are each intersected by a cup holder. A recess in the cup holder has a forward tilt relative to a horizontal axis having an angle between approximately 20 degrees and approximately 40 degrees toward the front end of the buoyant pool lounge chair. In operation, when the buoyant pool lounge chair is supporting a person while the buoyant pool chair is floating in water, the forward tilt of the cup holder provides a compensating-leveling mechanism that mitigates spilling of liquid in the cup when the cup is placed within the cup holder.

A lift chair frame is disclosed having an adjustable seat including a front support bar assembly including a left member and a right member connected to the left member, a rear support bar assembly opposite the front support bar assembly along a longitudinal direction, a left support bar connected to the front and rear support bar assemblies, and a right support bar opposite the left support bar along a lateral direction that is perpendicular to the longitudinal direction and connected to the front and rear support bar assemblies. The lift chair frame also includes an adjustable back coupled to the adjustable seat, where each of the left and right members includes a plurality of alignment features positioned in predetermined locations that correspond to predetermined adjustable seat widths, such that during assembly one of the predetermined adjustable seat widths can be achieved by 1) aligning one of the alignment features of the left member with one of the alignment features of the right member, and 2) securing the left member to the right member.

A mat comprising an array of elongated buoyant elements enclosed in a casing or cover that may be waterproof or porous. The mat may be readily rolled into a cylindrical shape up for purposes of transportation and storage. A pillow may be removably encased in a pocket in the mat, and the pillow may be removable as desired. The pillow may be inflatable, whereby the user may select the extent of inflation (i.e., the hardness of the pillow) in order to provide a desired level of comfort.

Disclosed herein is a meditation apparatus comprising a meditation seat and articulated pad that is lightweight, compact, and easy to transport that is suitable for indoor and outdoor use, wherein the articulated pad is pivotally connected to the seat.

A multi-positional chair assembly comprises a frame portion defined by a pair of sinuously-shaped bars. The frame portion includes a back support section, a middle section, and a buttocks support section. The sections are joined at multiple junctions defined by a bowed shape. A resilient panel traverses the pair of sinuously-shaped bars, providing a supportive surface for a user. The panel may include a resilient metal sheet, apertures, or parallel strips of material. The frame portion can be positioned in multiple positions to provide a sitting surface, including a lounge chair position and a higher elevated stool position. The chair assembly reconfigures between the lounge chair position and the stool position through rotation. Rotating the buttocks support section and the legs to engage the ground surface achieves the lounge chair position. And rotating the back support section and the legs to engage the ground surface achieves the stool position.

An apparatus that supports a user in a variety of positions to comfortably perform tasks, such as applying one or more tattoos to skin of a subject is herein disclosed. The apparatus can be reconfigured to optimally position and support the arms and/or chest of the user. A method for using a stool can involve rotating armrests of the apparatus from a stowed position to a deployed position. The armrests can support the user's forearms while supporting the user's chest such that the user can comfortably perform tasks in front of a chest support of the stool.
