A foot support connected to the frame of a wheelchair having a housing having a primary end located opposite a secondary end with a central bore. The central bore of the housing retains a rod. The housing has at least one opening. The opening of the housing reveals a revealed portion of the rod when the rod slidably traverses at least a portion of the length of the housing. A support structure is in communication with the revealed portion of the rod. The support structure supports the weight of a user's feet when a user is seated in the wheelchair. The support structure slidably traverses the length of the opening of the housing. When the support structure is oriented in a position located under the seat of the wheelchair, the rod is retracted within the central bore of the housing located substantially near the secondary end of the housing.

A sport chair includes a seating surface operative to support a user and a processor. The processor is configured to detect the presence of a user on the seating surface, establish communication with an article of apparel on the body of the user, receive an indication of a physiological parameter of the user from a biometric sensor provided with the article of apparel, and output the physiological parameter to a display.

An ergonomic chair has a back support member and means for arranging and supporting legs of the user in an asymmetric configuration, with a first leg extending in front of a body of the user and a second leg aligned with or extending behind the body of the user. An angle between the first and second legs in a side view can be at least 30 degrees. The means for arranging and supporting legs can comprise one or more fixed structures that support the first leg in a first orientation, or one or more dynamic structures that can be positioned by the user to support the first leg in a first orientation. In some embodiments, with the legs of the user in the asymmetric configuration, a centerline of the user is offset from a centerline of the back support member with respect to a lateral direction.

The invention relates to a recliner device for supporting a lying person, the recliner device having a foot and arranged thereon (i) a first movably mounted thigh support for supporting the first thigh of the person, (ii) a movably mounted second thigh support for supporting the second thigh of the person, the second thigh support being independent of the first thigh support and being combinable with the first thigh support to form a complete support, and (iii) a movably mounted back and head support that is independent of the first and second thigh supports.
