I was so pleased with the ambulance - review here:http://www.playmofriends.com/forum/index.php?topic=1279.0 - and the new medical helicopter (review shortly) that I have also bought the doctor and incubator and the wheelchair and patient (review to follow). So here's a review of the doctor and incubator.
The incubator has collapsible legs, an opening clear plastic top, a removable mattress and grips at each end for manoeuvring the unit. Quite which is the correct way for the mattress to go in is open to question as the box shows it one way and the instructions the other. I decided that the box seemed the correct way, with the baby's head towards the main monitoring panel.
The top lifts up for access, and there are also two holes for access in the side panel when the top is down.
