Designed and manufactured by Arthur with exceptional support and comfort in mind, the King Arthur Pocket Sprung Mattress is a sleeping solution you’ll never want to leave. Featuring a medium firm tension and is available in single, double, king size, and super king, browse the amazing qualities of the King Arthur below and be on your way to super sleep in no time.

Two layers of supportive pocket springs

For one of the most supportive mattress types, you can rely on King Arthur’s 2000 pocket springs. Each individual pocket spring is encased in its own fabric pocket and move independently, allowing the mattress surface to move to the contours of your body. With 800 pocket springs at the base of the mattress and 1200 mini springs in an additional layer, the King Arthur will promote even weight distribution, minimal motion transfer and unparalleled pressure relief.Please note, mini springs feature within the top layer of the mattress.

Luxurious layers of foams

Accentuating the body-moulding support and comfort of the pocket springs, the King Arthur incorporates luxurious comfort foam layers throughout the mattress. Including memory foam and reflex foam layers that conform to your body shape, foam also helps reduce motion transfer even further. Providing ultimate comfort, you’ll receive many years of fantastic night’s sleep with the King Arthur.

Which? Best Buy endorsed

With the King Arthur mattress, you can sleep easily knowing it's Which? Best Buy endorsed. The King Arthur has undergone rigorous testing to ensure the mattress's suitability and a Which? Best Buy rating. The testing criteria revolve around breathability, stability, body support, and whether you can turn on the mattress easily. To assess the mattress for back support, Which? measures the shape of a person's body at 36 different points when standing and then when lying on their back on the mattress. Similarly, they measure the position of their spine when lying on their side to check that no part of their body sinks too far into the mattress. Other testing procedures include specially designed equipment to assess whether the pressure is evenly distributed across the mattress surface and specially designed humidity chambers to measure how much moisture can pass through the mattress's layers. To test the mattress's durability, heavy barrels are run back and forth across the mattress thousands of times to simulate approximately ten years of use.

Vacuum packed delivery

Looking for a mattress that provides simple delivery? All Arthur mattresses arrive rolled and vacuum-packed, so it’s super easy to manoeuvre to the bedroom of your choice. Once there, remove from box and packaging and leave for 4-24 hours. This revolutionary way of transporting and delivering mattresses makes purchasing a new sleeping solution much easier.

How do I know a medium firm mattress is right for me?

The King Arthur features a medium firm support tension, ideal for people who sleep in a variety of positions throughout the night. This is because the mattress is neither too firm nor too soft to support you on your back, stomach and side, all of which require a different support tension in order to adequately promote healthy spine alignment. The versatility of a medium firm tension means it is perfect for couples as you and your partner can both sleep in your preferred positions.
