Booster Seats on Emirates?

[ihearttc]

Just wondered if anyone knows if you can check a child's booster seat on a Emirates flight and if you have to pay for it?

CAn you put it in your luggage or get a bubble bum instead?

It won't fit in our luggage-its actually a trunki boostapack but we aren't using it on the flight so thought it'd be easier to just go in the hold.

I did look at a bubble bum but the reviews were better for the Booster Pack.

There is nothing on Emirates website so might just have to call them.

The good thing about the bubble bum is its inflatable so rolls up to nothing, can carry it around in handbag in case get in a taxi, bus etc on holiday.
Could you take the booster as hand luggage?
