I'm fed up buying those boxy storage single beds as my son is about 18 stone and goes through them fairly quickly.
Saw "The Worlds Strongest Bed" advertised
video here

Trying find off the site how to order and delivery charges.
Anyone help?

The site has a contact link here - clicky

And also a telephone number - Tel: 028 3083 4963

Drop them an email and ask for a price list. When enquiring about delivery charges, don't forget to add your postcode so they can work it out.
