What size bed do you sleep on and why did you choose it?

I currently have a queen that is falling apart and i just ordered a brand-new Full bed and a brand-new full mattress slightly smaller but i wanted more room for my computer. I paid about $1250 including delivery and installation a little pricey but health is more important and my current mattress is falling apart as well not good for my back or neck.
