photoshop - How to set patters on sofas with indent , different shapes and angles

I have a problem with setting a pattern on sofas . The image below is a pattern that I set to a sofa : http://ift.tt/1yCrj3X

as you can see, the pattern comes from up to down in a straight line . this is wrong ,I need it to covert the corners , do the indent and ....

for better understanding the correct way , please see the below image ,I saw this on a website ,as you can see , it isn't in a straight line ,it goes in the corners , rotate and exaclty get the shape of sofa . http://ift.tt/1pN37vl

This is exaclty what I need to do but I don't know how .How can I do this ?

Looking forward to hear from you
