This past weekend, we went to Babies 'R' Us to purchase this. They have all the samples of baby carrier out for sampling. I know I only wanted Baby Bjorn as I read about it, the baby carrier can be taken off so easily especially if you want to put down a sleeping baby. The carrier comes in two separate parts and to put the baby down, you just need to unbutton (6 buttons) the front panel and lay the baby down. It is very EASY to put on and take off, unlike some other baby carriers. This carrier can be used for baby as young as 1 week old with at least a minimum weight of 3.5 kg/8 lbs and a toddler with a maximum weight of 12 kg/26 lbs. The top of the front panel gives a strong head support for younger baby who needs to face inward when carrying. And when the baby has a stronger neck, he/she can face outward and the head support can be folded down giving the baby a stronger chest support. There is also an adjustable buckle at the bottom of the carrier to fit baby at a different height.
So while we were there, I tried on the baby carrier original ($79.99) and the one with back support, baby carrier active ($119.99). I found the original is the best to fit me as the one with the back support is heavier and very complicated to put on. I didn't feel much different with the back support, may be I ought to wear on longer and it may make a different. At the end, I've made my mind and went with the classy Black Color Baby Bjorn Baby Carrier Original since is cheaper. See pictures below.
