I'll start with the seats: they have completely changed how the seats are designed. They are far more supportive and have these really nice cushion-like supports all over them. There's even extra padding for a headrest. They sit at a much higher angle than previous models. There is even a lumbar support. The recline feature has also been revamped and is much simpler. No more buckling and unbuckling. The seat does not go completely flat, but it goes flat enough, even for an infant. Because of the change of design in the footrest area - there is actually more leg room. The 5 point harness is padded where it needs to be and easily adjustable. Something I especially like is they've added a little buckle at the top where the harness fastens to seat allowing you to move it higher or lower, depending on the size of the child.

The canopies: these things are HUGE! The best I've come across. Also redesigned in the 2011 model. They are now ratcheting and seem to go even further... Read more

After six months of use as a full time nanny/baby planner:

Pros:
- Super easy to push, even with toddlers
- Turns on a dime
- Amazing shade
- Waterproof material
- Front lockable swivel wheel for jogging/tough terrain
- Peekaboo windows, but with loud velcro
- 5pt harness
- (just barely) fits through standard doorways

Cons:
- Heavy, heavy, HEAVY!!! Do not expect to be easily whipping this stroller around, it weighs a ton.
- The fold is huge, which is to be expected with this type of stroller, but makes it hard to fit in a standard sized car. Between the weight and size of the fold, it is hard to carry it up or down even a few stairs.
- It is a three part fold that requires two hands, esp annoying when you have a baby old enough to sit in the seat but not old enough to sit completely unassisted on the sidewalk
- The handlebar is not adjustable. I am tall, so this is particularly annoying to me.

Recently purchased this stroller to use with my newborn and 2 year old. The stroller is great! It turns on a dime and folds up relatively small for a double stroller. My husband took my 4 year old and 2 year old out for a run and said it was super smooth and easy to push. The kids loved it! My only complaint is that the handle bar is not adjustable. FYI: Make sure you order the NEW 2011 Car seat adaptor for this stroller. The car seat adaptors currently being sold on amazon are not compatible with the new 2011 BOB strollers. I found this out the hard way and had to return the car seat adaptor I purchased.
