Is one location but has not got your bed though, that name brand seems to be some multi part investment group with no parent company so allows people to use that brand name for their own purposes as long as it fits in with the objectives.
Now that bed I notice seems only to be with Littlewoods, Very and I think Tesco so I think its a special made for those concerns at a suitable price and not part of a branded range sold to others like the link. So if you did find their "Home" they would possibly say no anyway and cite that it was made for their customers and they have the rights to them.
This I am afraid is normal these days I have a swan fridge and badged but Swan denies it because it was made for their customers (like above plus Argos, Currys etc etc)
Yet you may find one in the link similar which may help.
Hope this helps..............
