A king size mattress is the standard for anyone looking to elevate their sleep experience. Measuring 150cm x 200cm (5ft x 6ft 6in), it provides a significant upgrade over a Double mattress. The extra 15cm of width may seem modest, but it makes a transformative difference for couples, allowing each person to move freely without disturbing their partner.
Our collection is designed for those who appreciate the finer details of sleep engineering. Every mattress in this range is handcrafted to provide the perfect balance of surface comfort and deep structural support. By moving up to a king size, you are investing in a larger, more restful environment that caters to your body's need for space and alignment.
Advanced engineering for a better night of rest
Individually nested pocket spring systems
The foundation of a great king size mattress is its ability to isolate motion. We use premium pocket springs that are independently housed in fabric pockets.
Zero motion transfer: Because each spring reacts individually, your partner's movements will not travel across the bed. This is essential for a 5ft mattress, ensuring both sleepers enjoy a peaceful night.
Tailored spinal alignment: The spring system contours to your specific body shape, providing firmer support for heavier areas like the hips and shoulders while remaining gentle on your joints.
Premium comfort and temperature regulation
A larger mattress needs to breathe to stay fresh. We utilise high-quality materials to ensure your sleeping environment remains at the perfect temperature.
Natural wool and cotton layers: These fibres are naturally breathable and moisture-wicking. They help to keep you cool during the summer and retain warmth during the colder months.
Advanced pressure relief: Whether you prefer the responsive feel of natural latex or the body-moulding properties of memory foam, our comfort layers are designed to reduce tossing and turning.
Hand-finished quality and durability
Each mattress is finished with traditional techniques that ensure it stands the test of time.
Side-stitched borders: Our king size mattresses feature reinforced side stitching. This strengthens the mattress edges, preventing sagging and allowing you to use the full 150cm width comfortably.
Traditional hand tufting: Functional tufts are passed through the mattress to keep the luxury fillings in place. This prevents the materials from shifting and ensures a consistent feel across the entire surface.

How do I choose the right mattress firmness?
Here are some factors to consider when determining the ideal firmness level for your mattress: Sleeping Position: Your preferred sleeping position can influence the ideal firmness level of your mattress. Body Weight: Your body weight can affect how much pressure you exert on the mattress and how deeply you sink into it. Personal Preference: Ultimately, the firmness level of your mattress should align with your personal comfort preferences. Some people prefer the plush feel of a softer mattress, while others prefer the firm support of a firmer mattress. Health Conditions: Certain health conditions, such as chronic pain or arthritis, may influence your choice of mattress firmness. In such cases, it's essential to consult with a healthcare professional for personalised recommendations.
Do mattresses come with a sleep trial?
Yes, typically they come with a sleep trial period, allowing you to try out the mattress in the comfort of your own home before making a final decision. During the sleep trial period, you have the opportunity to sleep on the mattress and determine if it meets your comfort and support needs. If, for any reason, you are not satisfied with the mattress during the sleep trial period, you may be eligible to return it for a full refund or exchange, subject to the terms and conditions of the sleep trial policy. This allows you to make an informed decision about your mattress purchase without the risk of being stuck with a mattress that doesn't meet your needs. It's essential to review the specific terms and duration of the sleep trial period for the mattress you are interested in, as these details may vary depending on the model and promotional offers available at the time of purchase. Additionally, be sure to follow any instructions regarding the return process to ensure a smooth and hassle-free experience.
How do I care for my mattress?
Here are some general care and maintenance tips: Use a Mattress Protector: Consider using a mattress protector to help prevent spills, stains, and dust mites from penetrating the mattress. A waterproof or water-resistant mattress protector can provide an additional layer of protection against accidents and spills. Keep the Mattress Clean: Vacuum your mattress periodically to remove dust, debris, and allergens that can accumulate over time. Use a handheld vacuum with an upholstery attachment to gently vacuum the surface of the mattress. Spot Clean Stains: If spills or stains occur, spot clean the affected area immediately with a mild detergent and water. Blot the stain with a clean cloth or sponge, taking care not to saturate the mattress. Allow the mattress to air dry thoroughly before replacing the bedding. By following these care and maintenance tips, you can help prolong the life of your mattress and enjoy a comfortable and supportive sleep surface for years to come.
Are mattresses compatible with adjustable bed frames?
Yes, many are compatible with adjustable bed frames, allowing you to customise your sleep position for optimal comfort and support. Adjustable bed frames, also known as power bases or adjustable bases, allow you to elevate or recline different parts of the mattress to achieve your desired sleeping position. When using a mattress with an adjustable bed frame, it's essential to follow any guidelines or recommendations provided by the mattress manufacturer to ensure proper support and functionality. Additionally, be sure to check the warranty terms and conditions to confirm that using the mattress with an adjustable bed frame does not void the warranty coverage.

Will a king size mattress fit on my current bed?
Our king size mattresses are built to standard dimensions. They will fit any 5ft King size bed frame or Divan base. It is always worth measuring your frame to ensure it is a standard 150cm width before ordering.
Is a king size mattress longer than a double?
Yes, a king size mattress is 200cm long, which is 10cm longer than a standard Double or Single. This extra length makes it the essential choice for taller sleepers whose feet hang off the end of shorter beds.
What level of firmness should I choose?
Firmness is a personal preference. Side sleepers usually benefit from a medium-soft or medium feel to allow their shoulders to sink in. Back and front sleepers often prefer a medium-firm or firm mattress to ensure their spine remains in a neutral, healthy position.
How is a king size mattress delivered?
Because of the size and weight of a high-quality 5ft mattress, we handle delivery with care. Our team ensures the mattress is moved into your room of choice. We recommend checking your staircases and hallways to ensure there is enough clearance for a 150cm wide mattress to pass through.
