All our mattresses are designed by experts, to provide support for a genuinely deep sleep.
Our medium mattress is popular with sleepers that like both medium and firm support. That's why we recommend the medium mattress as the safest choice if you are unsure between medium and firm.
If you're unsure about your preference, a good place to start would be to try our mattress topper first. That way you can experience our different support designs before committing to your mattress.
