Was after a decent quality airbed and seemed to have missed out on all the budget ones available the last few weeks.
The coleman comfort double gets the best reviews online (e.g. amazon):http://www.amazon.co.uk/Coleman-Comfort-Phthalate-Double-Airbed/dp/B0030BGA6O
Ordering online puts this at about £25 (with postage). Or you can get it in Yeomans for £19.99. Spotted it in Blacks (half-price) for just £17.50!
Very happy - lets hope it lives up to the hype.
