Description

FIELD OF INVENTION

This application is generally related to a device for supporting an individual and more particularly related to supporting a standing individual.

BACKGROUND

Many individuals suffer from back pain, which is usually either chronic or injury related. Back pain can be caused by a variety of medical conditions, i.e. strain, herniated discs, sciatica, and spinal stenosis. Back pain can be particularly severe when an individual is sitting in a traditional chair with a flat sitting surface. The flat sitting surface can cause back pain or discomfort.

Recent studies have indicated that sitting for prolonged periods of time, particularly at a desk, can have adverse health effects. Further, other studies have indicated that standing can increase work productivity and efficiency.

Known solutions for addressing lower back pain caused by sitting include exercise ball chairs, lumbar supports, standing desks, kneeling chairs, and reclining chairs. None of these known devices provide both alleviation of pressure on the lower back and a restful support.

SUMMARY

It would be desirable to provide a support device that alleviates lower back pain and is comfortable.

An adjustable support apparatus including a base with horizontal support members is provided. The adjustable support apparatus includes a first upright support member of a first predetermined height that is supported at one end thereof on one of the horizontal support members, and an other end of the first upright support member has a first support that is generally parallel to the one of the horizontal support members. A second upright support member is supported at one end thereof on a second one of the horizontal support members, and an other end of the second upright support member has a second support that is generally parallel to the second one of the horizontal support members.

Preferred arrangements with one or more features of the invention are described below and in the claims.
