This is the old style Chicco Hug 4 in 1, with opaque (not mesh) sides. The stock picture attached is the newest style Hug 5 in 1 (you cannot detach the crib part in this 4 in 1, I think that's the only function difference).
The whole frame is on wheels so you can move the cot or chair as needed. The frame has adjustable heights - photos show it at its lowest and highest and you can stop it anywhere between those.
For the crib/sleep setup, we are including the official mattress and 3 sheets (2 plain white and 1 with little sleepy sheep on) - see pictures. Apologies we don't really have a proper photo of it set up in the bed mode, just this one of her stretching in it!
For the chair setup it comes with the straps and white padding as pictured.
The chair/crib comes off the frame for transporting, but the frame is a little heavy so I would say not suitable for public transport - bring a car (we have free parking).
I have vacuumed, dusted and hand washed all the relevant bits but it is used so it will show signs of use from the 15 months we've had it!
I'm pretty sure we still have the instructions somewhere too, I will dig around...
Feel free to send any other questions.
