Floating raft bed alternatives

[Juniper Rivers]

Hello friends,

 

I am trying to find an alternative to polystyrene floating raft beds and am curious if anybody on here can point me in the right direction.  I remember seeing a youtube video months ago where some people were using raft beds that appeared to be made out of plastic and fit together almost like a puzzle in an interlocking fashion.  These seem ideal and I would love to find some for a closer inspection.   Any information or help would be greatly appreciated.  Thanks!
