If the majority of your clientele are over 200 lbs, you may want to invest in a table with at least 3" of padding. Sure, a 2" or 2.5" pad would be ok as well. However, the less padding that there is, the quicker it may ware down over time. So why not get a table with a little extra padding? This will not only add an extra level of comfort, but increase the amount of time that your table will remain comfortable.
The width of your table also plays a key factor in comfort because everyone loves a spacious table that doesn't leave their arms hanging off of it. A 28" wide table is considered a standard sized with 30" being considered as a full-sized massage table. Be sure to keep in mind that tables with thicker padding and wider dimensions, weigh more overall. With that being said, if you are traveling regularly, you may prefer a standard portable massage table with a 28" width for less bulk and less weight, making your trips a bit more manageable.
