Fold down seats for rear of cockpit

[Montemar]

I am looking for fold up seats that I can attach securely to the rails at the rear of the cockpit ( Broom 33 ) that can have removable cushions. This will allow me to increase seating as needed by simply folding down probably with a hinge down leg to take some weight.
I have found buddy seats for camper vans but nothing in stainless steel suitable for a marine environment.
Any suggestions would be greatly appreciated.
SORRY I SHOULD HAVE POSTED FOLD UP SEATS

Readily available from many chandlers such as Force 4. P 186 of their catalogue.
