A living manifesto in ten objects:

#6 Sofa
(of the house by the sea, even if you do not own one)

CARTE BLANCHE ANTONIO SCARPONI • 23.08.2018

Read the manifesto in our first article #1 Armchair.

A sofa is a spaceship. It is a steady place, from where different life adventures start, as well as literary and non-literary vicissitudes. Love stories, intrigues, crimes and uncountable passions take place in the pages of the books read and among the cool sofa cushions in a lazy August afternoon. And if you get caught off guard by sleep, this sofa will fly you to the sweetest dreams. Wherever you are, you will always feel at home, in the house by the sea which you do not have

A, B, C, D, E, G, P. FSC certified fir strips, planed and variably sized. The profiles are available in length of 1 m or 2,5 m and can be bought in any DIY store (e.g., Coopbau, Jumbo, Migros DoIt, Bauhaus etc.). With this scheme you can get the pieces cut on site by the customer service offered by a.m. retailers. Try to select the profiles with fewer knots and as straight as possible.
F. FSC certified fir strips, class B. Size: 1.8 x 30 x 200 cm.
H. Electric drill / screwdriver, with 3mm wood drill bit.
I. Screwdriver; we recommend to use an electric screwdriver.
L. Pencil.
M. Extensible measuring tape.
N. Hole drill, ø80 mm.
O. Drywall screws 3.5×35 mm, black (important).
Q. FSC certified fir strips, class B. Size: 1.8 x 40 x 60 cm.

Mark with the pencil (I) the measures shown on each end of profiles of type C/D/P. Pay attention: mark profile C on one end as defined in C1.
Use the wood drill tip (H) to drill the holes according to the measuring marks. Use the first drilled profile as an example to drill following drills. We suggest placing a scrap under the profiles while drilling to avoid damage to the underlying surface.

Use profiles E as legs of the portal frame of the sofa to be made. Profile C must be placed in the upper part paying attention to the position of the C1 angle variant. Screw profile D opposite to profile C, positioned at 30.7 cm from the lower end of profile E. Make the portal frame of the sofa complete by placing the stiffening crossbar P. Place the elements correctly according to the C1 side.

Mark with the pencil (I) the measures shown on each end of profiles of type A/G. Use the 3 mm wood drill tip (H) to drill the holes according to the measuring marks. Use the first drilled profile as an example to drill following drills. We suggest placing a scrap under the profiles while drilling to avoid damage to the underlying surface.
Mark on panels F the quoted measures, drill the holes by using the 3 mm wood drill bit (H). Screw the two A profiles onto the F panel by using the O screws.

Fasten the two portals of the sofa to the A and G profiles which form the carrying structure.

Stiffen the frame made by the F panels and screwed A profile. Fasten the free side of panels F with profile A forming the frame. For further stiffening, fasten the A profiles to each other along the entire centreline. A further stiffening can be achieved by placing a 7 cm long screw into the portal piece D in order to fasten it to profile A which has been previously fastened to panel F.

Mark with a pencil (L) panels Q, paying attention to the measures quoted. With hole drill N make a 80 mm hole in the middle. Drill holes at the marks by using the 3 mm wooden drill bit.

Fasten panels Q onto the frame of the sofa. Make holes at a regular distance in the middle of profile G by using the 3 mm wooden drill bit in order to fasten the backrests Q.
Use O screws to fasten panels Q at a distance of 7.5 cm from one other, proceeding along the profiles A and G.
Stiffen profile G by using profile B. Place it in the middle by forming a L, as shown in the drawing.

The sofa is now ready. To finish, use three hard cushions with a maximum size of 65x65x10 cm. In this way you will be able to transform the sofa into a single bed. For the backrest, use three soft cushions with a maximum size of 65 x 50 cm. Two extra cushions can be used at the armrests to make the sofa complete. We suggest to use cotton or linen fabric.
