we have replaced wood on garden bench. but it is wobbling side to side it has
all its straps etc. does the wood lats have to be very tight into each end ? the
sides wrought iron are Lyon heads which are old but I'm stuck on how to get this

We normally call that 'racking'.
To minimise racking, yes.
Ensure the slats are attached to the ends as tight as possible
(without crushing the wood etc) and if that isn't sufficient, add some
(two) diagonals across the back (could be wires or flat steel straps)
to further restrict said racking.
Even one diagonal would help.

Unless there's some diagonal bracing, it's quite optimistic to hope the
wooden slats alone will stop it rocking.
What is needed is new slats that completely fill the holes in the sides.
Given that the slats have already been cut to size, it might be worth
cutting a few wedges and hammering those in to fill up the gaps. If
there's any movement, they'll probably tend to work themselves loose. At
least, it will enable you to see how rigid you can make it just with the
slats before going to the trouble and expense of getting new ones.
I suppose that is because in order for the metal ends to go "off
vertical" the slats all have to become misaligned. And the strap goes a
bit of the way towards making the slats more like a solid sheet, with
shear strength. Slightly surprising, but if it works...
