Not wood at all. They are very compact and I can fold them in half and just put them in a Ziploc bag for traveling perfect I wear a size 11 so I ordered the large 11 to 12 and they fit perfectI?ve already use them at least six times in my water exercise classes and they are more comfortable than any book you would issue I have ordered in the past I recommend them highly I love the ability to take them off and use the sliders on carpeting as well and the plastic for the sliders is not the thin plastic like cheaper sliders I have had in the past! I love the Apple Magic Mouse. ;) All in all, Im really pleased with this charging stand and would definitely recommend! Not worth the trouble Really soft, comfortable, and fit as expected. He happy?? Iam happy ?? This was the perfect workaround. Also the L shaped pins that hold the leg rest up and bench flat tend to slide out constantly when moving the bench around the room.
