Can pocket sprung mattress be put on slatted wooden bed frame?

Hi - I bought a Habitat Euro King size bed frame some time ago in a sale, thinking that when I have enough money, I will buy a mattress from Habitat for it. Long story short, they have discontinued Euro Sizing. I currently have a very old 2400 18 yr old Relyon mattress which cost us the earth. I couldn't pay that amount of money again (newly divorced) but want to know if a mattress intended for divan can be put on Wooden Frame bed (it has no end, just head board if that helps at all). Thank you in advance for any help/information you can give. Rosie
