At 150cm wide, the True Rest King is our largest mattress, 15cm wider than a Double. It shares the exact same construction as every size we make: a supportive base, a pressure relieving memory foam layer, and a breathable Aurora® Foam top, no springs involved.
It arrives compressed, rolled and boxed, and unrolls straight in your bedroom. Once unboxed, most memory foam mattresses reach around 90% of their full size within 4 to 6 hours and are safe to sleep on straight away, with full expansion typically taking up to 72 hours.
Every True Rest mattress is manufactured in the UK, tested to BS 7177 fire safety standards, and made with CertiPUR™ certified foam. It's also fully recyclable once the cover is removed.
The True Rest Difference
Better Sleep. Better Days.
True Rest was born from a simple realisation: better recovery starts with better sleep.
Created by former Lancashire County Cricket Club player Chris Tipper following a life-changing injury, True Rest has been developed to deliver more than just comfort. It combines carefully engineered support, pressure-relieving comfort layers and breathable sleep technology to help your body recover, restore and prepare for the day ahead.
Every component has been selected with purpose, creating a sleep system that supports deeper rest, better alignment and long-term comfort. Because when you sleep better, everything else has a better chance of performing better too.
Better spinal alignment
Targeted 5-zone support helps promote healthy spinal alignment and balanced comfort throughout the night.
Improved pressure relief
High-density memory foam gently contours to your body, helping reduce pressure on key areas.
Deeper, more restorative sleep
Designed to support deeper, more restorative sleep so you can wake feeling refreshed.
Enhanced recovery and next-day energy
Quality sleep supports recovery, helping you feel more energised and prepared for the day ahead.
