## Abstract

There is provided an ergonomic chair which is produced from flat components. The components may be made of paper. The components are designed using parametric equations which take the targeted user's proportions into account. The components are then folded, joined, and coated with strengthening material. The chair has a seat, a base, and three legs connecting the seat to the base. The base contains a counterweight mass for keeping the chair in a default upright position. The base contains an accelerometer which can transmit data to a computing device to track a user's posture and other health-related data.

## Claims

### Claim 1

A chair comprising:
a base including a counterweight;
a seat connected to the base and supported above the base by a seat-supporting structure, and
wherein each of the base, the seat and the seat-supporting structure are made at least in part of folded paper substrate material that forms at least one cavity that includes a castable material within the cavity.

### Claim 2 (depends on 1)

The chair of claim 1 further comprising:
a single accelerometer for providing position data;
a wireless transceiver for communicating wirelessly with a computing device and for transmitting the position data to the computing device.

### Claim 3 (depends on 2)

The chair of claim 2 further comprising a vibration motor for generating vibrations as feedback to a user.

### Claim 4 (depends on 1)

The chair of claim 1 wherein the folded paper substrate material is coated with a cellulose nanocrystalline (CNC) coating.

### Claim 5 (depends on 1)

The chair of claim 1 wherein the folded paper substrate material comprises printed graphics.

### Claim 6 (depends on 1)

The chair of claim 1 wherein the seat-supporting structure comprises a plurality of legs that include a paper substrate mass.

### Claim 7 (depends on 1)

The chair of claim 1 wherein the castable material forms the counterweight.

### Claim 8 (depends on 1)

The chair of claim 1 wherein the castable material defines a paper substrate mass.

### Claim 9 (depends on 8)

The chair of claim 8 wherein the paper substrate mass is formed of a pulp-glue mixture.

### Claim 10 (depends on 9)

The chair of claim 9 wherein the pulp-glue mixture contains cellulosic fibre-reinforced filaments.

### Claim 11 (depends on 10)

The chair of claim 10 wherein the accelerometer is on a position sensor circuit board that also includes a microprocessor to determine if corrective action or user notification is required based on position data obtained by the accelerometer.

### Claim 12 (depends on 11)

The chair of claim 11 wherein the position sensor circuit board is within the base.

### Claim 13 (depends on 1)

The chair of claim 1 wherein the chair has dimensions tailored to a user.

### Claim 14 (depends on 1)

The chair of claim 1 wherein the paper substrate material is folded to conceal raw cut edges.

### Claim 15 (depends on 1)

The chair of claim 1 wherein the paper substrate material are folded to form male and female joints.
