It's kinda like adding just a little more changes it. And it does. It's called super size for that reason I suppose. Supersize this meal and you may as well supersize everything else to go with it. The chair above is a size bigger. It is definitely super sized. My daughter and I could both sit in the chair easily. Although we are wearing smiles in the picture, it is not a laughing matter. These chairs were found in the doctor's office for sleep disorders (although I have also seen the size difference in the public restrooms lately). That being a circle story: weight can interfere with sleep and lack of sleep can increase your weight. How about we just super size the word super by adding the letter "p", then it will be supper and that would explain the extra size!?
