I bought the Joovy Caboose and returned it. I bought it when my youngest was an infant and in an infant carrier. When I installed the infant carrier into the seat of the stroller I had to recline the seat all the way, and when I did that my oldest was not about to sit in the back seat (if you can call it a seat).

I saw sit n stands and they didn't seem to have that problem. I ended buying a graco duoglider and liked it for awhile, but wanted a stroller I could walk with, so I saved money and bought a double BOB. I did not want to buy one, I thought they were too expensive and too wide. Since I bought it, off eBay, I have not used another double stroller but BOB. He goes to SeaWorld, Disneyland, the mall, everywhere.

 Good luck on your search!

We have a sit n stand and I really like it. My oldset is 6 and my youngest is 2 and they both still use it at disneyland.

We have a sit n stand and love it. It is a nice change to using the huge double stroller, on smaller trips. My two youngest are 2 ( almost 3) and 14 months, works great! Pretty light weight as well

Take your kids to the store to check it out.  I wanted the sit-n-stand too b/c I did not want a big bulky double stroller.  My oldest was 2 at the time.  He did not like the sit-n-stand, so I finally bought the Graco DuoGlider.  My oldest is now 4 (and 4 ft tall & 50 lbs) & still sits in the back of the DuoGlider at Disneyland!  Good luck!

We have graco duo glider as well for our main stroller! It's big and heavy, but it is a wonderful stroller, plenty of room for both of our younger boys

I have a Joovy Ultralight - LOVE this stroller. Nothing to complain about in 3 months of use. I have a 3 yr old and 3 month old in it, both pretty average height/weight kids. Infant carrier attachment works great, and the stroller fold super flat and is awfully light for a double!
