Small bedroom or a solo sleeper? Then a single mattress is probably just what you need. We have a limited selection of standard single mattresses which measure 90cm x 190cm available at great prices. This is the nearest equivalent to what used to be traditionally known as the 3ft mattress. Scroll to the foot of this page for more tips to help you pick the right option. *Please note mattresses featured here are not included in our 100 night trial.
