If cared for correctly, a luxury bed mattress will give you good service for up to 8-10 years. The Knightsbridge range of mattresses are layered with quilted memory foam on both sides, in order that you may seasonally rotate and flip the mattress which will maintain both the lifespan and the support that the mattress gives you.

Over the coming year, you’ll probably spend at least 2500 hours asleep in bed and the quality of that rest will impact many areas of your life. Getting a good night’s sleep on a regular basis is known to be vital for improvements in daytime energy levels and alertness, as well as providing long-term health benefits. There are many changes that can contribute to improved sleep but undoubtedly the one with the biggest impact is an upgrade to your mattress.

The Sloane & Sons Knightsbridge mattress is pocket sprung, containing 1200 individual springs, evenly spaced throughout the mattress to provide maximum comfort and support. This system is one of the best ways to reduce pressure points whilst sleeping, making it essential for anyone who suffers from a bad back or joint pain. Each spring is able to work by itself, allowing the mattress to provide even, targeted support, regardless of your favourite sleeping position.

A pocket sprung mattress reduces the amount of movement transmitted if you share you bed with a restless sleeper, helping to reduce midnight disturbances. This system is also very beneficial if there is a difference in size between you and your partner. The numerous springs act to support each person independently, ensuring that you both reap the benefits of a stable, comfortable surface.

On top of all this, the Knightsbridge mattress also features a layer of quilted memory foam, further increasing your night-time comfort. Well-known for its abilities to reduce tension in the body, memory foam is a unique material which moulds itself to the contours of your body and provides a smooth, relaxing feel, while still maintaining maximum spinal support.

This Sloane & Sons mattress is double-sided too, with memory foam on both top and bottom, enabling it to be easily flipped over. A good mattress is a valuable investment and a little bit of care will help to keep it in top condition for as long as possible. Most experts recommend turning your mattress every 3-4 months to maintain optimum performance.

Another great feature of the Knightsbridge mattress is the Tencel fabric, which is made out of natural fibres from eucalyptus trees. This environmentally friendly material has a soft, luxurious feel and is highly breathable, efficiently wicking moisture away from your body, while still being durable and long-lasting. It is naturally antimicrobial, which is great for people with allergies, and also helps to reduce odours.

Measuring 153cm x 200cm this Sloane & Sons Knightsbridge mattress will fit perfectly on any king sized bed. A depth of 24cm gives an indulgent level of comfort, but won’t make it difficult to find sheets to fit. The pocket springs and memory foam combine to provide a medium firmness mattress - the perfect balance of softness and support at a level which is favoured by most people.

Buying Guide

Buying Guide

At Sloane & Sons we understand the importance of a good mattress. At the most fundamental level, a good mattress equals a good sleep, which equals better health. It might sound obvious but you'd be amazed at just how damaging the health effects are of poor sleep. (Don't take our word for it - here's what the NHS has to say.)

Buying a new mattress is a brilliant step towards a great night's sleep. But which mattress should you buy? We want to make sure you make an informed choice, so do please read on. If you still have questions, we would be very happy to speak to you on the phone or via email - don't hesitate to get in touch.

Our primary message is: don't compromise on quality. Being uncompromising doesn't have to cost the earth though - we keep out prices as reasonable as possible but always keep our standards sky high. With our mattresses lasting up to 10 years so, they are a small price to pay for the comfort, relaxation and better health you'll have as a result 365 days a year.

Sloane & Sons specialise in the two most popular type of bed mattress: memory foam and pocket sprung. We know that many retailers, both online and on the high street, offer thousands of choices but there really is no need. It ends up as confusing rather than helpful. We feel that by having a smaller, more focused range of high quality products, this allows you to choose more easily based on things like size, comfort, firmness, price and type of mattress.

Memory Foam Mattresses

Memory foam was developed initially by NASA as a material that would absorb great pressure from astronauts' bodies as they re-entered the earth's atmosphere. Today, this technology makes wonderful mattresses as it can relieve stress and pressure points on your body as you relax into the supple embrace of the memory foam.

  • Memory foam moulds as your body heats up and softens the core around you
  • This allows both support as you lie still but also natural and free movement during sleep
  • Alignments of the spine (horizontally) ensures correct posture
  • Memory foam has hypo-allergenic and anti-microbial properties

Memory foam is ideal for people experiencing joint pain and for people who suffer from allergies. Many people without these issues also enjoy the feeling of warmth, support and comfort that memory foam provides.

Pocket Sprung Mattresses

Pocket sprung mattresses are the most common and popular type of mattress in the marketplace. They differ significantly from cheaper alternatives such as bonnel spring or open sprung bed mattresses, which we believe are less comfortable, less supportive and not as good value for money in the long term.

The reason is that pocket sprung mattresses compartmentalise each individual spring in order to evenly distribute the weight and respond to the different pressure points and weights of your body.

  • Ideal if you and your partner differ in height and weight. They will evenly distribute the pressure within the mattress and prevent you from rolling into one another
  • Sloane and Sons mattresses have approximately 1200 individual pocket springs per mattress that are individually housed and this is the benchmark for high level craftsmanship
  • Each 'pocket' works independently from another, to evenly distribute weight
  • This style of mattress allows a good airflow around the body, keeping your comfortable through the night and refreshed in the morning

All Sloane & Sons mattresses have hand-stitched sides and piped edges that underline the quality of design and craftsmanship.

I didn't realise how uncomfortable my old mattress was until I slept on my lovely new one. Great value and excellent quality. I need a double bed mattress for my guest room and I know where I will be purchasing it.
