This chair is part of my latest Achvis. In the following article I am going to show you how I have created this beautiful chair.

Step 1:

Open Blender. I am using version 2.67. You should also have 2.67 or higher to follow this tutorial.

Step1

Step 2:

Change your Render-engine to Cycles. Load in a background image. I have used an image that I have found on the webpage of Katja Reiter. She is one of the two designers behind this chair. This is the link to the picture.

Step2

Step 3:

Delete three faces of the default cube.

Step3

Step 4:

Next you have to duplicate your modified cube. Rotate it by 90 ° and place it underneath your original U-shaped cube. Select the top edgeloop and pull it downwards.

Step4

Step 5:

Enable the snapping tool. Select Vertex mode.

Step5

Step 6:

Snap the four vertices of the lower element to the one of the top element as shown in the picture. But don’t press remove doubles.

Step6

Step 7:

Continue by adding a subdivision surface modifier. You can do this by choosing from the menu or by clicking Ctrl +2. Open the toolbar and set the shading of the object to “Smooth”

Step9

Step 8:

Go ahead and add in several loop cuts along almost every edge. This will help you to difine your edges and corners better.

Step10

Step 9:

Select the two two centre loop cuts and grab them along the y respectively the z axis.

Step11

Step 10:

Select the top-right-corner-face. Press X to bring up the Delete menu and select “Only Faces”.

Step12

Step 11:

Reenable the snapping tool used in Step 5. Snap the vertices as shown in the picture.

Step14

Step 12:

Finally select everything by pressing A. Bring up the Specials menu by pressing W. Finally select “Remove Doubles”. This will give you a very smooth edge as it is desired.

Step15

Step 16:

Press Z to change to the wireframe view. Select one half as shown. You can do this by using either pressing C to bring up Circle Select or B to open the Border select tool. Once everything is selected press X again and choose “Vertices”.

Step16

Step 17:

Add a mirror modifier to the chair. Place it before the Subsurf modifier.

Step17

Step 18:

Screen18

Step 19:

Apply both the Mirror and the Solidify modifier. You will come up with something like this:

Step18

Step 20:

Add two more loop cuts at the edges at the head sides.

Step19

Repeat this process for the second element.

Step20

Step 21:

Press Tab to change to Object-mode.  Re-centre your Cursor by pressing Shift+S.  Now you can add in a lattice at the centre of your grid. You can open the “Add”-menu by pressing Shift+A.

Step21

Step 22:

Place by pressing g and scale the lattice by pressing s so that it covers the whole seat. Now change to the Lattice menu and turn up the U-value to 3, the V-value to 3 and the W-value to 3.

Step23

Step 23:

Select the seat object and add Lattice modifier. Select your lattice.

Step24

Step 24:

Now you can start “sculpting” your lattice.  Just press Tab to go into edit mode and tweak the vertices (g). Always do the same transformations for the left and the right side.

Step25

Step 25:

Finally you should come up with something like this:

Step26
