A toilet chair includes a support frame, and a platform connected to the support frame. The platform is connected to the support frame at a first end with at least one horizontal strut. The platform is configured to move with respect to the support frame and includes at least one clamp at a second end. The at least one clamp is configured to lock the platform to the support frame at the second end forming a horizontal platform. The toilet chair also includes a toilet seat assembly connected to the platform. The toilet seat assembly is configured to support a user and move with respect to the platform.

The novel impedance matching toilet seat apparatus in general, includes a cavity, an acoustic transducer, orifices, and an impedance matching substance dispenser. The cavity is positioned on a top surface of the toilet seat. The acoustic transducer is positioned within the cavity. The orifices are positioned on the top surface adjacent the acoustic transducer. The impedance matching substance dispenser is within an interior portion of the toilet seat. The dispenser includes a reservoir, a conduit, and a pump. The reservoir contains an impedance matching substance and is connected to the conduit and pump. The conduit fluidly connects the reservoir to the orifices.

A toilet includes a bowl and a seat. The bowl includes a base and a rim. The base includes an inner surface and an outer surface. The rim includes an upper surface and an inner surface. The inner surface of the rim extends from the inner surface of the base. The seat includes a plate portion, a neck portion, a skirt portion, a first fastening tab, and a second fastening tab. The plate portion includes an inner edge and an outer edge. The neck portion extends axially from the inner edge of the plate portion. The first fastening tab extends from the neck portion and includes a first aperture having an axis configured to intersect one of the inner surface of the rim and the inner surface of the base. The second fastening tab extends from the neck portion and including a second aperture.

Provided is a method of manufacturing a toilet seat that is formed by joining together a seat front member and a seat rear member. The method includes a cutting step of forming a processed surface of a joint part between the seat front member and the seat rear member by cutting the joint part between the seat front member and the seat rear member with a cutting tool having a curved cutting blade part such that the shape of the processed surface is formed in a curved shape in which the seat rear member side thereof protrudes outward in a cross section perpendicular to the direction in which the joint part extends.

The present invention is directed toward a prefabricated shower curb system for easily providing a shower area with a water-retaining curb. The prefabricated shower curb system is formed mainly by a body that has a C-shape and includes a recess, and that is preferably manufactured from a rigid foam material such as expanded polystyrene. The body is mounted onto a wood, aluminum, or other support member arranged along a shower floor entrance area. The support member is secured to the shower walls or to an adjacent support member through brackets. A waterproof liner is used to cover and protect the support member. An adhesive material and the tapered interior design of the body recess allow the curb to be firmly secured in place on the supper member. The extraordinary strength, light-weight, low-cost, and easiness of size adjustment make the system novel in the industry.

An adjustable toilet seat riser, including an upper seat with an upper seat bridge, a lower platform including a lower platform bridge and at least one sleeve, and a spring, where the spring is internally positioned in the upper seat bridge and the lower platform bridge when upper seat is secured to lower platform. A method of installing an adjustable toilet seat riser on a toilet, including, compressing two arms of the adjustable toilet seat riser, relaxing the two arms of the adjustable toilet seat riser when positioned on a toilet, and engaging at least one sleeve on the adjustable toilet seat riser to an inner rim of the toilet.

Disclosed is a posture device configured to provide a support surface for a user. The device comprises a body, the body having a front end and a rear end, and an upper surface between the front and rear ends, the upper surface providing the support surface, the body being constructed from a resilient material, such that in use, the material generates a resilient return force in response to the user's weight, said resilient return force encouraging a posture in which the user's pelvis is neutral or slightly anteriorly tilted.

A chair assembly including a toilet seat, a chair seat lid and a backrest. The toilet seat, the lid and the backrest are connected relative to one another such that they are positionable in alternative chair and toilet-use modes. The lid is behind the generally upright backrest when the assembly is in the toilet-use mode and is on the toilet seat when the assembly is in the chair mode. The assembly can have self-supporting legs whereby it can form a standalone chair remote from the toilet. When in a male urination mode, the toilet seat is lifted and the backrest is in a lifted, generally horizontal position.
