The king size mattress is our second largest mattress size, measuring five feet wide by six feet six inches long (150cm x 200cm). Choose between pocket springs and non-sprung options with Emma. We can usually deliver our selection of king size Emma mattresses in as little as three weeks, so a good night's sleep is never far away. Having worked in the industry for years, Emma is aware of the importance of a mattress for a good night's sleep. Making extremely comfortable and supportive mattresses is their area of expertise. They take into account temperature regulation, pressure point relief, optimal spinal alignment, and a restful night's sleep.

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.
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.
A 200 night sleep trial period, free UK delivery, a 10-year guarantee, and financing options like interest-free credit with no deposit and buy now, pay later with Klarna are all available for all king size Emma mattresses.
There are alternative sizes available if an Emma king size mattress isn't what you're after. Single, small double, double, and super king size options are among them.
