An inflatable seat having an internal inflatable tube disposed within a cloth barrel and framed by a pair of fixed planks secured to a pair of internal connector rings and a pair of plastic shields and covered by a decorative canvas.

According to one aspect, embodiments of the invention provide a recreational floatation device comprising a body portion comprising an inflatable member having a first inner perimeter surrounding a first inner area, a first support portion comprising a layer of material extending through the first inner area and attached to the inflatable member at its first inner perimeter to support a user of the device, a back support member located within said first inner area, a hinge mechanism coupled to the back support member and the first inner perimeter and configured to allow the back support member to rotate between a first position, wherein a substantial portion of the back support member extends generally away from the first inner area, and a second position, in which the back support member lies substantially within the first inner area.

A seat assembly is provided with a seat cushion and a pivotal seat back. Sensors are connected to the seat cushion and/or the seat back to detect a seating position. An actuator is connected to the seat cushion and/or the seat back for adjustment. A controller is configured to receive data from the plurality sensors, compare the data to determine if the occupant is seated evenly, and adjust the actuator to balance the occupant posture seating position. The controller is in electrical communication with an inflation device to inflate a first air bladder assembly in a thoracic region of the seat back. A second air bladder assembly oriented in a lumbar region, a sacrum region, and/or a scapular region of the seat back is inflated after initiating inflation of the first air bladder assembly for sequential posture alignment.

A seat air bladder assembly is provided with at least one central air bladder region having a support surface. At least one pair of lateral air bladder regions extend from opposed sides of the at least one central bladder region. The at least one pair of lateral air bladder regions are oriented at a non-zero angle to incline laterally and support a thoracic region of a seat occupant. A seat assembly is provided with a seat back with a contact surface with a thoracic region. An air bladder assembly is oriented within the thoracic region of the seat back with a support surface that is reclined relative to the contact surface to provide support, and wedge-shaped so that during inflation the air bladder assembly inflates in an upward and forward direction relative to the seat back.
