I used one of these after the birth of my third child, and I think they should be required after each pregnancy!  I used to own a boutique and sell these in my boutique, and all of my customers absolutely swore by them.  You can even use them months after pregnancy and still see results.  The bamboo and the couture are the most comfy - I would not recommend the regular one at all as it is stiff and can be very hot.  The couture is covered in a spandex like material, which makes it easy to wear.  The only downfall to most is that you probably do need to purchase 2 sizes of these, which does get extremely expensive.
