Please see below the various Comfyzak sizes available, when deciding on a size its important to take into account the following:
1. Recommended Floor Space - This is vitally important as it will dictate up to what size Comfyzak can fit into the intended space.
2. Usage - What would you like to use your Comfyzak for? Couples and families, where there will be more than 1 user(therefore a medium or bigger); Nesting, Gaming, chill pads, office seating etc
3. The User - We are all blessed to be unique individuals, because of this please take into account the height and weight of the user(s) that will be using the Comfyzak to ensure their comfort and support; while all sizes can be used the smaller sizes understandably would not be all that comfortable for tall, broad or heavier users. For example we don't recommend any size smaller than a medium for individuals close to 6 foot.
