We were torn between getting a pack n play for our family room and one for our bedroom for the first few months, or getting the pack n play for the family room and the arms reach cosleeper.
I think we've finally decided to do the cosleeper since it has a higher weight limit, but I can't find it in stores anywhere, just online.
This is the right one that works well for two babies, right...?

Thank you! 
Re: Is this the "correct" Arms Reach cosleeper?
Thanks!
Did you go to crib(s) after that, or something else?
If you are going to have them sleep together you'll need the orig sized one. If you want them apart- 2 of the minis will work great - that is what we have - one on each side. We moved them to their cribs at 5mo, but still have them in our rooms for nights like the past few when Gibby had a horrible cough - it was nice to be able to have him come sleep next to me again - though, he's almost too big for it now
they are GREAT!
We didn't actually end up using our Cosleeper that long. There was nothing wrong with it, but our boys were just really bad/noisy sleepers at first, so by the second or third week, DH and I ended up sleeping in shifts. So one of us would sleep on the guest bed in the nursery (with the babies in a shared crib the first 6 months) and the other slept in our bed and our room. We moved the cosleeper downstairs and used it like a pack n play. It does work for a lot of people to have their twins in their room and if our boys had been better sleepers, I would have loved it!
