Delimitation of the present study: The study was limited to

selected Sankheda Sofa chair design available in Baroda city.

Methodology

The assessment of existing furniture and redesigning of

Sankheda Sofa Chair were the requirements of the present

study. The electronic media was used to collect the ergonomic

checklist to collect information about the existing sofa chair. For

the present study the researcher had selected only one Sankheda

Sofa Chair to ergonomically design checklist. The checklist had

the dimensions of existed Sankheda Sofa Chair.

The data which included dimension of Sankheda Sofa Chair

were collected personally by the investigator with the help of

metallic measuring tape. The drawings were with the help of

Autocad and 3-D Max software. The drawings of existed

Sankheda Sofa Chair with Plan, Elevation and Side Elevation

were designed. And the drawings of proposed Sankheda Sofa

Chair with Plan, Elevation, Side Elevation and 3-Dimentional

view were also designed.

Results and discussion

This section covers the dimensions of the existing Sankheda

Sofa Chair. For proposed designing of Sankheda Sofa Chair

anthropometric measurements were consider.

The researcher had proposed one modified design of Sankheda

Sofa Chair. i. The researched developed an ergonomic checklist

for existing Sankheda Sofa Chair found the following. The

breadth of existing Sankheda Sofa Chair seat is 20” inch only

found by the researcher. For sitting of user with heavy bottom

wider seat is required. Therefore the seat breadth for the

proposed sofa chair was increased so as to fit the widest bottom

width and knee to knee width to sit comfortably. So the

researcher suggested breadth should be increased to 26” inch. ii.

The researcher also purposed an increased in the backrest

breadth to match with new seat breadth. The researcher

proposed 26” inch backrest breadth. The researcher proposed in

the new design a neck rest to support the neck and head of the

user. The neck support has 2” thick cushion to support the skull.

iii. The backrest angle was100o degree to the horizontal. It was

not proper for relaxation. According to Keegan and Akerblom

the angle between seat and backrest should be between 105o to

110o for a comfortable chair

3,4. The angle of backrest was

increased to 100o

to provide relaxation to the user at home. iv.

According to ergonomic checklist OSHA ergonomic checklist

the armrest height should be between 8” to 12” inch. The

armrest height was 5” in existing Sankheda Sofa Chair. The

researcher recommended the armrest height should be increased

to 8” inch. v. The researcher suggested the armrest breadth to

increase to 3” inch for comfortable support for the lower arm. In

the existing sofa chair it was having circular shape with 2”

diameter. It was not able to provide support for lower arm. vi.

The researcher had suggested other changes in the dimensions

of Sankheda sofa chair which are given below. The researcher

had also provided two dimensional drawings of existing

measurements of Sankheda sofa chair and proposed Sankheda

sofa chair. The drawings were made exactly to scale with the

help of Autocad and 3-D Max software. The proposed

modifications were suggested by the researcher were as follows:
