Input: Consider Input: Naader was my first yoga teacher. When we moved out of state, this video was my link to the best yoga routine I have ever done. I tried other instructors and other videos, but Naader's approach is the best -- a balanced mix of yoga instruction and inspiration. I have shared this tape with many friends (who then bought their own copy!) and they all agree that Naader's instructions are easy to follow and the pace is slow enough that beginners can figure out what is going on before the next pose; but not so slow that experienced students get bored. Furthermore, since he is doing the poses along with the student, he knows just when to offer that extra word of encouragement when you are about to give up! I find something new to ponder each time I listen to this tape. Naader's words are from the heart and they reach out to touch your heart as well as your body. Buy this tape and use it!!

Input: Consider Input: A comfortable bed for the money. But I've had 7 or 8 of these, and they ALWAYS fail in one of two ways:1) An external seam will break, usually near the head area. To fix it, use a good size piece of Gorilla Tape (forget the enclosed repair kit) and press down very hard around the leak so no air can get out. No need to deflate or remove flock from the area, but you have to press down carefully and firmly.2) An internal seam will pop (usually in the middle) and create a huge bubble in the center. No way to fix that, unless you want to use pillows or folded blankets to level out the low areas.That's my advice. I'm still looking for a good, sturdy alternate model.
