Great for a comfortable night’s sleep. Excellent value for money. CONS While some buyers like a memory foam top layer, others may prefer standard foam or natural materials.

Main Benefits As a British made product complying with all safety regulations, you can rest easy knowing that this mattress is well-constructed and safe. It features 3 support systems – designed to offer comfortable support throughout the night. The National Bed Federation have also given this mattress model their seal of approval.

Meanwhile, allergy sufferers will likely be attracted by the mattress’ hypoallergenic properties. Construction and Materials The 3 primary support systems consist of an Open Coil Bonnell spring unit, a high-density reflex foam layer, and finally, a memory foam layer. Reflex Foam is a popular, cost-effective alternative to memory foam, offering many of the same benefits – typically at a lower price-point.

The mattress is vacuum packed – making delivery and initial positioning simpler. On the flip-side, however, the lack of handles on the sides could make moving this mattress awkward if it needed carrying to another room in the future.

Its pocket sprung construction offers fantastic weight distribution. As the name suggests, this king size mattress was designed with postural support firmly in mind! Main Benefits With a name like the ‘Royal Ortho Supreme’, it may seem that this king size mattress has a lot to live up to! But the manufacturer, Relyon, is a British maker of high-quality beds and mattresses with a long history and a proud reputation for excellence. This best king size mattress is designed to provide firm orthopaedic support. The 2200 pocket springs ensure that pressure points are avoided – instead, the user’s body-weight is supported evenly right across the surface. Pocket springs also have the benefit of working independently. This reduces the chance of large areas of the mattress being compressed by the user’s weight (which can cause ‘roll-together’!) Anyone suffering from back or joint problems could well benefit from choosing this product. Anyone favouring a firmer, more supportive mattress will enjoy the great night’s sleep that the Royal Ortho Supreme offers. High Build Quality There’s no doubt that the manufacturer, Relyon, has taken pains to ensure a high-quality product. The materials used and construction standards are superb. Additional support has been added to the side areas (which can sometimes be less firm than the centre of a mattress). High-end natural materials have been selected (including silk and cashmere). Silk offers excellent absorbency and is often noted for its cooling effects. Cashmere is a form of goat’s hair traditionally prized for its exceptional softness. Features and Specs 2200 pocket springs Pocket sprung for enhanced support Reinforced perimeter and sidewalls Premium quality materials Dimensions: 200 x 150 x 30 cm Conclusion Excellent for anyone experiencing back problems, this best king size mattress provides firm support.

What to Look for When Buying a King Size Mattress Believe it or not, your king size mattress is a big part of your life! You’ll likely use it almost every night for the next 8-10 years, depending on the quality of your king size mattress. Most people spend around one-third of their lives in bed! And making the best decision when you buy a king size mattress can have a significant impact on your health. In some ways, you could say that there’s no such thing as the best king size mattress, only the best mattress for you! So, before we jump right into the process of reviewing and comparing products, we’ll start by looking at the different features available and the points you should consider when buying. King Size Mattress Size Guide! Let’s start with a simple question – what size is right for you? If you already have a bed, then selecting the size of the mattress is easy. You simply choose what fits your existing bed! (Feel free to skip forward to the ‘Support’ section below if you’re already sure you need a UK 150 x 200cm king size). However, if you’re buying a new king size mattress and bed, then you have a choice between a standard double, a king, and a super king. Here’s a size guide for each: Standard Double: 135 x 190cm King Size: 150 x 200cm Super King: 180 x 200cm So, which is best? Once again, there’s no one right answer, only the correct solution for you. As a rough guide, most people prefer a bed/mattress at least 10cms longer than they are tall. This makes a king/super king the best option for anyone more than 180 cm (5’11’’). You’ll also need to consider whether you’ll be using the bed alone, or with a partner. Think about your body size/s and your sleeping habits – do you tend to lie stationary throughout the night, or do you often move in your sleep? Lastly, don’t forget to factor in the scale of your bedroom. How much space is needed for other furniture? How much room do you need to move around the sides of the bed? All of these factors can help you choose the correct size. We believe that for most people, a king-size mattress offers the best blend between the need for extra space while you’re sleeping, with the need for a bed that fits properly within your room. The extra length is a handy plus point if you’re tall and the extra width makes for a larger sleeping area. But crucially it doesn’t come with the considerable width of a super-king mattress – a size which simply doesn’t work in most people’s bedrooms. So, if you’ve settled on a king size mattress and bed, you’ll need to be sure you choose the right size, king! You see, just to make things confusing, king size mattress dimensions vary slightly! The standard width for the UK made king size is 150cm, while the European standard is 160cm. If you’re buying to fit a bed frame you already own, then you need to be sure to select the correct mattress size! To keep things simple, the mattresses we’re looking at here are all manufactured in the UK to the standard UK dimensions (150 x 200cm). Support People come in all shapes and sizes! Selecting a product that offers the best support for your body is key to making the right choice. A good mattress should comfortably support your weight without sagging. You should be able to move and turn on the mattress without noise or excessive resistance from the springs (if it uses springs). And, it should regain its natural shape quickly after you leave the bed. If you’re of a larger build, elderly, or suffering from a condition such as arthritis, joint problems, or back pain, then selecting a mattress that provides optimal support becomes doubly important. Comfort While it’s crucial to choose a mattress that offers excellent postural support, you also need to select a model you find comfortable. Again, there’s no one-size-fits-all solution here – some people find a firmer mattress more comfortable, while others prefer something soft, spongy. To make things easier, mattresses are graded according to how firm they are. Categories include soft, medium, firm, and extra firm. Mattresses are sometimes also described as medium/firm (for example) if they fall between two groups. You’ll likely have a clear idea of your preference based on the mattresses you’ve owned before. Having said that, new mattresses are continually being developed with modern materials that offer a far better night’s sleep than a mattress from, say, 20 years ago ever could. Materials and Construction In writing this best king size mattress guide, one of our key areas of focus was the quality of materials and construction. Once, an outercourse fabric stuffed with horsehair (or even straw) was the best most people could hope for! Thankfully, things have moved on since those days! There are now a wide range of different materials available. These include: Foam Light and comfortable, offering excellent, even support for the user. Memory Foam Is a responsive material that becomes pliable in response to body-heat; memory foam adapts to your natural contours for fantastic orthopaedic support. Some sprung/foam mattresses feature a memory foam topping for extra comfort. Open Coil Springs A traditional method of construction, each spring provides support for the user’s body. Pocket Sprung The individual springs are wrapped in a fabric pocket. King size pocket sprung mattresses are famous for their excellent levels of support and are especially beneficial if you sleep on your side. Zoned The spring’s firmness and density are highest in the areas (zones) where the most support is needed. Buy Online!
