Making the cushions

To make the cushions, simply create a box and add multiple segments to it (I added 30 in the height and length). Then add a cloth modifier and open up object properties and tick the box that says cloth then in the drop down menu underneath, select cotton and add 44 pressure (under where it says pressure) then click O.K. Once that is done, go down to where it says gravity and change the number to 0 so the object doesn't fall when simulating then click "simulate local" and when the box hits the size and shape which is desired then click "simulate local" again to stop the simulation.
