I decided to prove to myself that I could (the author says), remembered AutoCAD from university, drew everything that needed to be cut, went to a construction supermarket, ordered polished chipboard and fiberboard for the linen box. I decided to make the bed with wide bylets under the mattress 180 * 200cm, so that I could put any book or mobile on them.
Project budget (in USD so as not to suffer with the course):
Chipboard $ 64, corners and fasteners $ 28, lamellas (platbands, pine) $ 34, Leatherette $ 53, foam rubber $ 51, lifting mechanism $ 38 (for 1200N - too much came out). In total, the bed is 267 and the mattress is $ 146.

Brought chipboard and dismantled the old sofa.

I put up the back side and try on the sides.

I attach it to the corners, and then to confirmations.

Putting the frame together.

I check the correctness with the top cover + the kote controls the quality.

Glass of red, drawing and control.

I check the rectangularity with the top covers.

I threw the mattress and realized that the gaps are too large between the mattress and the frame, I did this on purpose, as more foam rubber and leatherette would be added.

Putting the frame under the mattress.

I attach it to the corners and to confirmations.

I cut the corners with trimming at 45 '- the car helped me out very much and also helped in the construction of the stairs in the country - I will lay out the report.

Confirmates.

I’m estimating.

The center plank supports the mattress frame.

I raised the entire structure on chairs so that I could work not on all fours and hide the edge of the leatherette from below. I lifted myself in a circle, I substitute the books (sadly) right up to the height of the chair.

I'm packing the balce.

It's the same.

Set.

I tighten the frame.

Foam rubber on the frame 20mm at the end 50mm.

I figured out the frame and realized that it is not included due to the fact that the foam rubber is 50mm at the end, despite the fact that I made a margin of 4 cm and the frame is smaller than the mattress by 4 cm.

He took off the casing again, cut off the foam rubber, got angry with himself and put it back together.

The frame stood up perfectly in every sense, put the lifting mechanism.

I figured out the mattress - a tunic in a tunic fit into the opening. I knocked down the fiberboard box for linen - lying under the bed.

He lowered him to the floor with the help of books again.

At work. The laundry box is huge.
