Quite honestly the best mattress I've ever slept on. I love it - for so many different reasons. Not only is it comfy, it's customisable (his and hers sides) the 100 day money back guarantee and the option to change firmness without replacing the whole mattress made it an easy choice to make. Saying it is excellent value for money is an understatement - we expected to spend 3/4 times what we did. To top it all off, customer service was second to none. I never had to chase for delivery updates and any queries I had were dealt with efficiently by informative and polite members of the team. It always felt like I was receiving a personalised service.
