Otty Natural Origin Mattress - EU King

• Hand-Stitched Tufted Cover. Handmade in the UK from premium viscose, with handles stitched into the sides. Those handles matter more than they sound, because this is a mattress you'll want to rotate and flip regularly.
• Needle Felt Layer. A naturally breathable, insulating layer that helps regulate temperature. In practice that means it holds warmth in winter and lets heat escape in summer.
• Comfort Polyester. A lightweight, durable layer that improves moisture-wicking. This helps keep the sleep surface feeling fresh and hygienic over time.
• Natural Rebound Cotton. Cotton breathes naturally and draws moisture away from you as you sleep. The result is a cooler, drier mattress, which hot sleepers will appreciate.
• Pocket Spring Core. The heart of the mattress, with 2,000 individually wrapped springs that respond independently to body movement. That independence means better motion isolation, so one restless sleeper is less likely to disturb the other.
• All The Layers Again, Reversed. The same layers repeat in reverse order on the underside. This makes the mattress fully double-sided and flippable, which helps it wear evenly for longer.
