Firm King Size Mattresses

Wake up feeling ready. The Emma Original Lite Mattress pairs breathable Airgocell® foam with a 3-zone pocket spring core — giving you the balanced, supported sleep your body actually needs. At 22 cm tall, four purposeful layers work together every night. The breathable Airgocell® top layer allows air to circulate through its open cells, keeping you cool and comfortable. Below that, SupportBase foam cushions your body and eases pressure on sensitive points, creating a smooth transition to the spring core. The edge-to-edge 3-zone pocket spring system divides into three targeted zones — shoulders, hips, and legs — adapting to your body's natural shape rather than treating it as one flat surface. The spring design does more than support. By running edge to edge, it lets air flow freely throughout the mattress, reducing heat and moisture build-up for a cleaner, fresher sleep environment compared to all-foam designs. The cover is soft to the touch, fully removable, and machine washable at 40°C — easy to keep fresh for years to come. The Original Lite is UKFR certified, medium firm (4 out of 5 on the firmness scale), and suits back and side sleepers well. Try it for 100 nights. Not the right fit? Returns are accepted and handled directly through Wayfair. A 10-year guarantee covers material defects in the spring core and foam layers. The Emma Original Lite: honest construction, lasting support, trusted by millions of sleepers worldwide. Winner: Best Mattresses, Sleep Awards 2024 by Expert Reviews.
