G’day Helen, I’ve just measured the Companion 6 Person Deluxe Quick Fold table myself, and you’re right – 50cm is way off! I think there must have been a slip of the finger there as it actually measures 5cm high when packed. Thanks for bringing this to our attention – we’ve fixed that up now so hopefully there isn’t any more confusion. As for whether this table can be left in the rain - we’d recommend that you keep this table undercover, a few splashes of water here and there will be fine, but if you leave it out in the rain it may cause damage in the long term.
