What it is: A system of 1,400 individually pocketed springs, each housed in its own fabric pocket.

Enhanced Breathability

How it helps you sleep: Promotes airflow through the mattress for a fresh, moisture-free sleeping environment.
Chrome Air Vents
What it is: Chrome-finished ventilation points set into the mattress border.
How it helps you sleep: Allow good air circulation to regulate temperature and keep the mattress fresh.
Tufted Finish
What it is: A hand-finished tufting method where the fillings are secured with tufts from the top of the mattress to the bottom.
How it helps you sleep: Keeps the natural fillings evenly distributed, maintaining consistent support and comfort for longer.
Flag-Stitched Handles
What it is: Handles finished with flag stitching along the mattress border.
How it helps you sleep: Make the mattress easier to position and manoeuvre during delivery and setup.

Vs softer mattresses: This mattress has considerably more structural support beneath its natural comfort layers than a soft or medium-feel option. Softer mattresses can feel more immediately plush, but this level of firmness maintains consistent spinal alignment throughout the night - particularly valuable for front sleepers and heavier individuals who need a surface that won't let the hips sink too far.
Vs entry-level extra firm mattresses: Many budget orthopaedic-style mattresses rely on open coil springs and synthetic fillings. This mattress uses a 1400-count pocket spring system with natural wool and cotton fillings, giving more targeted support and better breathability than a typical entry-level firm mattress at a similar price point.
Vs premium and luxury mattresses: This mattress shares the same natural, foam-free approach to fillings found in higher-priced ranges, along with a genuine pocket spring system. The difference is typically in the depth and number of comfort layers rather than any compromise in the quality of materials used.
The Rest Assured Arden is backed by Rest Assured's free 15-year guarantee against defects in materials and workmanship. Combined with the natural, foam-free construction and 1400-count pocket spring system, this is a mattress built to provide many years of supportive, comfortable sleep.
National Bed Federation (NBF) Approved - Independently verified to meet strict UK standards for quality, safety and responsible manufacturing.
Allergy UK Approved - This mattress's Purotex probiotic treatment carries Allergy UK's Seal of Approval, giving allergy sufferers confidence that allergens have been independently and scientifically tested for.
The Rest Assured Arden delivers genuine orthopaedic-level support, natural foam-free fillings and Allergy UK approved allergen protection, all handcrafted in Great Britain and backed by a 15-year guarantee. If you're a front sleeper, a heavier sleeper, or simply want maximum support with minimal sink, this is a mattress worth considering.

Bought this as my husband has back and hip problems. Where the mattress hasn’t solved that problem it has enabled him to sleep in much more comfort. It arrived quickly and was easy to sort out. I am very pleased.
