The seats are made of two parts, the fixed couch in blue (although it can be disassembled and stored to get more space) and the mobile part in cyan for the legs and feet. In this model I choose to represent the CSM in lunar orbit with only Mike Collins on board since the two other astronauts are already on the Moon in their 1/32 LM. So only the Commander seat is fully deployed to allow piloting the spacecraft in the best conditions. The two others seats were probably stored when Mike was alone but it was difficult to represent it on this model. The astronauts couches are available on Shapeways
