Emma's Premium King Size mattresses

Emma offers three different tension options for their double mattress line: firm, medium firm and medium, to suit a variety of sleeping positions.

Emma mattresses ensure a calm and relaxing sleep every night by using memory foam to relieve pressure points and conform to your body. We have the ideal option to suit your needs, whether you're searching for the cooling qualities of the Emma Luxe Cooling King size mattress or the tried-and-true comfort of the Emma Original mattress.

The Emma One mattress is the best-selling Emma® mattress in the UK, and for good reason! All types of sleepers will benefit greatly from the pressure relief and support provided by this mattress. It has three layers of foam, each with the ideal amount of firmness and comfort in mind. This well-made king size mattress will provide you with a restful night's sleep.

From the moment they go to bed, users of the Emma® Diamond Hybrid Mattress experience a noticeable improvement in their quality of sleep, as they can achieve up to 10% deeper sleep. With the help of foam and pocket springs, the Diamond Hybrid Mattress provides exceptional comfort and support along with a sense of movement and bounce. The clever use of graphite foam, combined with adaptive comfort foam and advanced HRX to keep your spine properly aligned for maximum relief, lowers the likelihood of sleep disturbances by regulating your body temperature for a cooler night.

Which? Best Buy certified as a premium mattress is the Emma Smart Hybrid mattress which combines memory foam and pocket springs. This is a great choice for those seeking a cooling, supportive, and comfy mattress at a great price.

Emma king size mattresses come with a removable and washable cover. Just unzip it, then wash it at 40°C to separate the top from the bottom.
