Portable bed for 25lb 1yr old?

[strusmom]

I have a 25lb 1year old boy. We travel back & forth b/w UK and US at 3x a year and he's my 2nd (e.g. alot of stuff to pack!).

1) Is there is a portable bed that packs lighter than a Pack N Play?2) Is there a compact (inflatable or v small) Portable High Chair?
2) How about a bathtub that packs very small?

THANKS!!
