Otty Natural Evolve Mattress - EU Double

• Hand-Stitched Tufted Cover. Handmade in the UK from thick viscose, with handles on the sides. That means rotating and flipping this heavy, double-sided mattress is far less of a struggle.
• Luxurious Wool, Silk & Cashmere. A blend of wool, silk and cashmere sits just beneath the cover. These fibres breathe and regulate temperature naturally, so the sleep surface feels soft without trapping heat.
• Natural Rebound Cotton. A layer of naturally breathable cotton that wicks moisture away. This helps keep the mattress cool and dry over time.
• 1750 Micro Pocket Springs. Smaller, high-density springs that respond to finer pressure points than a standard spring unit can. You'll feel this as gentler cushioning at shoulders and hips, with less partner disturbance.
• Natural Rebound Cotton. A second cotton layer, again breathable and moisture-wicking. It keeps airflow moving between the two spring systems.
• Core Pocket Spring Unit. Individually wrapped springs that adapt to your body shape, which means proper spinal alignment and reduced pressure points. This is the mattress's main support engine.
• All The Layers Again - Reversed. The whole construction is mirrored on the other side, making the mattress fully flippable. Flipping spreads wear evenly and extends the mattress's lifespan.
