La-Z-Boys are really rather comfortable, essentially the Rolls Royces of reclining armchairs - but that's where the comparison to cars ends.
Unless, of course, you go ahead and customise the things so they turn into motorised wheelchairs - but with comfy cushions.
As an example of someone doing just that, witness this daredevil relaxation-appreciator as he blasts down a busy road without a care in the world. We'd make one ourselves, of course, if we weren't so scared we'd crash into a tree.
That said, now we come to think of it, motorised armchair racing would make a fantastic extreme sport. Almost as fantastic as blobbing here, to be honest...
