Garden swing seat/picnic table

A friend has a timber garden swing seat with cover that converts into a picnic table with two side benches. She bought this some years ago at a garden/flower show.
Does this sound familiar to anyone? I would like to buy one or get something similiar but haven't seen any in garden centres or other usual garden furniture outlets.

I'm not really sure if I understand how your desired seat works; but have you thought about getting one made. If you live in South Dublin there is a very good place who make up garden swings, seats etc. It is call Timbertrove, previously known as Kelly's Sawmills on Scholarstown Road, Rathfarnham.
I have no connection with them apart from having them make a few things for me. I found the products well made and not very expensive. Here is their website
Even if you don't live close by try something similar in your area.
