Where to buy a foam chair bed?

Hi,

A few years ago, my sister bought 2 foam chair beds to have on standby should the kids have someone over on a sleepover etc. I think she bought them in Argos.

I am now looking to buy some and cannot seem to source them anywhere. I've tried Argos, B&Q, Woodies, Dunnes, furniture stores, mattress stores but no joy.

I'm in Galway but have to go to Cork, Limerick and Dublin regularly enough on business.

Can anyone advise me where I can get one or two of these in any of the above 4 cities please?

Thanks!
