25,26; 3, again that seat cushion 22 is superimposed at

chair pin

23,24, the

chair pin

25,26 that second step was folded is included in the hollow bulb 233,243 of

chair pin

23,24, and

chair pin

23,24,25,26 is included in the

groove

4,5 of seat cushion 22 bottom surfaces 225 entirely, promptly finish the superimposed of chair portion 2.4, after aforementioned three steps, again that it is superimposed on two

connectors

14,15 of table portion 1, wherein, form articulation structure 142,152 in

connector

14,15 ends 141,151 of

chair pin

23,24 bottoms 234,244 and table portion 1; The activity point of view of this articulation structure 142,152 only has the scope of invagination 90 degree, and it is superimposed at

connector

14,15 to make chair portion 2 pass through

chair pin

23,24 downward invaginations.5, through after the aforementioned folding program, it is superimposed at body 13 it to be made progress again, wherein, the end 143,153 of

connector

14,15 and the root edge 131,132 of body 13 also form articulation structure 133,134, make the

connector

14,15 can be upwards folding and superimposed at body 13; In addition, the root edge 131,132 of body 13 not only forms articulation structures 133,134 with the end 143,153 of

connector

14,15, it also is extended with catch 135,136, this catch 135,136 extends to

connector

14,15 ends 143,153 belows, 143,153 compactings of connected
