A Bit About Memory Foam

Memory foam consists mainly of polyurethane as well as additional chemicals increasing its viscosity and density. It is often referred to as “viscoelastic” polyurethane foam. Higher-density memory foam softens in reaction to body heat, allowing it to mold to a warm body in a few minutes. Newer foams may recover more quickly to their original shape. 


Originally developed by NASA during the Apollo program to support astronauts during lift-off and re-entry, memory foam is now mostly used in mattresses and has undergone many changes since it’s inception in the 1960s.

Memory Foam when used in a mattress can absorb body heat, creating a warmer nights sleep, however some people do not like this quality of memory foam and so temperature regulating materials such as cotton can be included in mattresses. 

Cool Blue Gel is a modern form of memory foam, which using a new formulation of base ingredients, provides the same comfort and support properties of memory foam, but disippiates heat much more efficiently creating a cooler sleeping surface. 

Memory foam mattresses come in two varieties, sprung mattresses and high density foam mattresses. Sprung mattresses generally have a longer lifespan due to springs superior support, a HD foam mattress may become softer over time as the foam is not under tension and will eventually lose its firmness. 

Memory foam isn’t for everyone and when buying any mattress it is recommended that you try before you buy so you know the level of support and comfort is going to be right for you.

Back Care Mattresses

If you wake up on a morning to find your back is aching or in pain, the culprit is often your old mattress. 

An old worn out mattress or a cheap mattress with inferior support springs can actually accelerate back problems, so investing in a comfortable supportive mattress is a very wise decision. 

To prevent back issues from occurring it is advisable to sleep on a medium-firm mattress, pocket springs are more beneficial as they contour to the shape of your spine.

If a firm mattress isn’t your thing consider a semi-orthopaedic which contains a strong supportive spring system with softer sleep fillings such as memory foam or cotton and wool. 

If you already suffer from an existing back problem then an orthopaedic mattress is likely what your doctor will advise you to sleep on. There is a huge range of ortho mattresses available today in a variety of firmness levels and will gradually ease your back over time. 

For the ultimate sleeping experience there are electric adjustable beds, also known as recliner beds or mobility beds. 

Combine a pocket sprung or memory foam mattress to an adjustable bed base and you will benefit from the support and comfort of the mattress with the added advantage of being able to angle and adjust your sleeping position for optimal comfort. 

Electric adjustable beds are most commonly used by elderly people needing mobility assistance and in hospitals so the majority of models come only in single sizes. 

Sure Sleep Beds in Doncaster specialise in heavy duty electric adjustable beds for use in domestic residence and commercial care homes. As well as hospital beds we also offer more homely recliner beds available in a variety of fabrics and colours to suit the interior of any home. 

Single mobility beds are the most popular size but electric beds are also available as a double if you need the extra space or want to share your bed with a partner. If two of you have different reclining requirement then dual motor options are available in king size and super king size options that feature two individual mattresses and two individual motors.

Whether you think you require a supportive orthopaedic mattress or an electric adjustable bed, both are a worthwhile investment and will improve back problems in time and contribute to better posture and a sounder nights sleep. 

Know your Bed Size

When buying new beds it is common for consumers to get a little confused as to the names of certain sizes. Where most of us are familiar with single and double beds, a few people sometimes aren’t sure whether the bed they have at home is a double or a king size. 

Single beds are 3 foot / 90cm wide, and small singles can be purchased at 2’6″ or 75cm wide. 

Double beds are 4 foot 6 inch wide or 135cm, and can also be ordered as small doubles at 4’0″ / 120cm wide. 

King Size beds are 5 foot / 150cm wide.

Super King Size beds, also known as Queen Size, measure in at 6 foot / 180cm wide. At Sure Sleep Beds we can have all Divan Beds and mattresses made to order in any width and length of your choice.

Know your spring system

Getting to know the difference between the different spring systems used in mattresses can greatly aid you in choosing the right mattress for your needs.

There are 3 types of support system commonly used in todays mattresses:

  • Open coil spring units
  • Pocket spring units
  • High density foam

Open Coil Springs

Open coil springs are a series of springs interconnected on a single unit that comprises the suspension system of the mattress. Open coil spring units come in 2 different gauges; 13.5g which are a softer tension and 12.5g which is a firmer tension. Orthopaedic mattresses tend to combine thick layers of polyester with firm 12.5g open coil springs.

Pocket Springs

Pocket spring systems are made up of thousands of fabric pockets, each containing a single spring that provides direct support to any weight applied. Since pocket springs are individually pocketed and not interconnected onto a single system like open coil springs, pocket sprung mattresses provide much better neck and spine support. Usually a higher pocket spring count means a firmer mattress.

High Density Foam

High density foam mattresses do not contain springs at all, and instead utilize a thick layer of dense foam to serve as the mattress support. Usually softer memory foam is added to the sleeping side to provide a more luxurious surface. High density foam mattresses are perfect for thos that don’t get along with sprung mattresses, however it has been known for the high density foam to ware quicker than sprung suspension mattresses.

Caring for your Mattress

When buying a new mattress it is important to look after it properly to prolong its lifespan. Some basic things you may already be aware of are not to jump up and down on the mattress like a trampoline and not to bend the mattress as this can damage its structural integrity.

Turning your mattress once a week from purchase will help the fillings settle into place, after doing this a few times it will only become neccessary to turn the mattress once a month. It is also important to use a breathable mattress protector as non-breathable protectors can cause the mattress to condensate.

It is good practice to regularly use a soft brush to brush down any dust and fluff from the mattress and never use a vacuum cleaner. Stains and spillages should be absorbed using a dry cloth or household paper towel products. Sponging with a damp cloth and mild solution of soap and water may also help lift some stains.

Choosing the Right Mattress

When choosing a new mattress it is important to consider your sleeping needs. If you have back problems it is recommended you get an orthopaedic mattress, as they are designed to provide a firm level of spine and joint support, easing the pain associated with certain back issues.

Most mattresses come in a range of firmness levels, sometimes they are labeled 1 to 5, 1 being the softest and 5 being the firmest. In reality there are far more than 5 firmness levels, and many mattresses considered the same firmness rating may differ in actual firmness. At Sure Sleep we simply label them soft, medium and firm to give you a better idea of the mattress you’ll be getting.

In addition to the firmness level, you may also want to consider the comfort fillings. Cheaper mattresses will feature Polyester fillings, where higher end mattresses may contain cotton, wool and luxurious fibres such as horse hair, cashmere or silk.

Choosing the right spring system can also make a difference, and they usually come in 2 types:

  • Open Coil / Bonnell Spring
  • Pocket Sprung
