I'm about to buy a small sofa bed for our little house, for me to sleep on every night. Needs to be no wider than 160cm and long enough when folded out to actually sleep on comfortably (some are ridiculously short!) and under £500. Black Friday may help with the latter! Want it to look like a traditional style sofa and preferably delivered in weeks not months. Would be so grateful for any suggestions and experience. IKEA doesn't have anything which meets the criteria, by the way. Many thanks.
