I'm sure you've noticed that every product that comes with a storage bag -- air mattresses, tents, sleeping bags, quilts, etc., -- all come with storage bags that are sized so that the intended contents can only be folded small enough to fit back into those bags if you are a professional "Folder," working from a Folding Blueprint, and have arms and hands as powerful as Popeye.
If you're a normal person, chances are that your best efforts, along with multiple re-folding attempts, will only result in a lump of product that either won't go into the storage bag at all or which sticks out of the end of the bag.
Message to manufacturers: You shit heads! I'm paying hundreds of dollars for your stinking product and you can't spend 30¢ to enlarge the stinking bag ... oh, maybe get crazy and slip in 6 whole inches ... so that normal people can put their valuable purchase away after using it. Sheesh!
