I've just bought one of these which might fit your requirements:

Haven't fitted the thing yet, so can't comment on practicalities, though
it looks well made etc

I can see the attraction, but bear in mind that as you get older, or
want to sell the house to someone older you may well regret having such
a high step.

It'd be no use in this house, for a start!
