what are the king size mattress dimensions?

The eve king mattress is suitable for all standard UK king-sized beds, measuring in at a spacious 150cm x 200cm (59 x 78 inches, or 4.9 x 6.5 feet).

the benefits of a king size mattress

All eve mattresses are designed to keep you comfortable, supported and at the perfect temperature – but our kings definitely go that extra mile. The perfect upgrade for a master bedroom, it’ll give you extra wriggle space, with plenty of room for the rest of the family. So spacious, you’ll wonder how you ever coped without one.

who will suit a king size mattress?

Upgrading from a double makes sense if you need extra room at night – particularly if there are little gate-crashers on the scene. For couples who cherish their space, or have different sleeping patterns, a king size could be a relationship saver.

will it fit my bedroom?

Grab a tape measure and ask yourself a few questions. Will there be enough room to walk around the bed? Will your bedside drawers still open? Will the bedroom door open freely? Will you be able to open the doors of your wardrobe or en-suite bathroom? Is there an easy flow of movement around the room? As for getting it up the stairs, all our mattresses are delivered rolled and double-wrapped minus the box, so there won’t be any ‘Ross from Friends’ moments.

200 night trial

The best way to get to know your mattress is to spend quite a few winks on it. So we’re giving you a whopping 200 nights to make sure it’s a match made in sleepy heaven. If it’s not, simply return it and we’ll give you a refund. We’ll let our mattress trial page tell you more.
