Attaching wheels to the sofa

As Jack and I have started filming we have encountered a few problems when it comes to transporting the sofa around. The sofa is possible to be carried however it takes a long time and isn't the pleasantest of experiences.
So we have decided to do a bit of D.I.Y on our beloved sofa.
 

We have taken the bottom of the sofa apart in order to find a way to put on a set of wheels that are the similar sort to the ones you find on a trolley in Tesco.
 
This in theory should allow us to push the trolley around quicker and with ease compared to having to carry it around everywhere. Hopefully as easily as this pug here.
Here are some images of Jack and I basically tearing the sofa apart in order to fit these wheels.
