Knee pads can be a pain in the butt to wear, but if the task at hand lets you remain relatively stationary you could try this knee cushion from Birkenstock instead. Of course, when you hear Birkenstock, you may think shoes, but surprisingly they also make this cushion to save your weary knees.
They designed this 15″-long by 9″-wide by 2-3/4″-thick cushion to cradle the knees and distribute your body weight evenly. Made in Germany, this dense foam polyurethane cushion is lightweight and sports a carrying handle.
Available in orange and apple colors, this pad seems a bit expensive at $36, but then again, so is knee surgery.
