Can anyone recommend a hanging chair that can swing in circles? DS2 finds the circling motion very soothing and calming which would be very useful for reducing meltdowns. Ideally I want one for indoors, but outdoors will do too. I've seen egg chairs on frames, but in the shops they're always tied to prevent you actually trying them, so I'm not sure if they will actually circle or if the frame would get in the way. DS is only 7, but one that would fit up to at least teenage size would be good. Needs to be stable as he can be a bit over enthusiastic with things, and accident prone.
TIA!
