Country of Manufacture : United Kingdom

Rest assured this product is not a cheap import, designed, produced and manufactured to the suppliers specifications, this product is entirely UK manufactured

Top Layer : Memory Foam

Memory foam is the most common comfort layer requested by customers within the industry. Made for NASA it has historic upbringing and is now used to offer impressive comfort in mattresses. Pros are that you will feel like you are sleeping on a cloud, cons are that it may get a little hot and sweaty and reduce movement in the summer. A modest amount of memory foam can oftentimes be more suitable than a thick slab for those looking to find the optimal amount of comfort through all seasons.

Cover Material Composition : 100% Polyester

A common material composition for covers, sheets and toppers, polyester is a man made fiber that is very resiliant and hardwearing making it ideally suited toward products in the mattress sector whereby the life expectancy can be upward of 7 years

Mattress Top Type : Tufted

Typically tufts means pocket sprung due to the nature of the design process. Tufts are necessary to ensure the mattress maintains its shape. Tufts do not impact on the comfort or support that a product offers, rather, a byproduct of good quality pocket springs

Mattress Turn : No Turn

A no turn mattress means that it does not need to be flipped, however, that does not mean that it should not be rotated. Always rotate your mattress seasonally to ensure the highest lifespan of the product

Hypo-allergenic : Yes

These mattresses are specifically designed for those that are prone to allergies, a hypoallergenic mattress will not necesserily guarantee you an allergy free experience, but it has the best chance of reducing the odds of complications or irritation for those commonly effected

Breathable covers are very important to maintaining a hygenic mattress. The amount of sweat lost while sleeping varies person to person but is generally pegged at 20-200ml/hour

Pressure Relieving : Yes

This mattress is specially formulated to relieve pressure on your joints and back due to the unique product design.

Bed Bug / Dust Mite Resistant : Yes

Bed Bugs are a huge threat in the home and one of the best ways to counter this is to purchase a product like the above that has bed bug and dust mite protection, this will help ensure that your home stays uninfested should an outbreak occur.

BS 7177:2008+A1:2011 Certified : Yes

This is the nationally recognised certification given to all products produced or imported to state that the product passes mandatory fire tests necessary for a product to be sold.

Firmness : Medium-Firm: Suits all sleep positions

A medium firmness is sort of the catch-all when recommending a mattress, too soft and you will not get the support necessary and will have pain in your joints and back as you sleep, too firm and you will have much the similar, contouring of your body with the mattress is hugely important and while weight, height and BMI all come into recommendations with the mattress, it is generally safe to recommend a medium firmness to the majority of people

Core Construction : Pocket Sprung

Many of the best matresses produced are those that invovle pocket springs, far better than open coil and arguably more supportive than reflex foam options, these are highly regarded as the best spring systems in class for mattresses

Low Motion Transfer : Yes

Your movement does not impact your partner who is fast asleep next to you. Ideal for those that turn a lot in their sleep, or like to...

BS 5852 Certified : Yes

This is a certification that means the product has passed ignitability of covers and fillings used in mattresses and other furniture.

Normal warranty within the UK is at 1 year so a 5 year warranty like the above is a big surprise and a sign of confidence that the retailer has in this product.

Mattress Construction : Core Construction: Pocket Sprung, Top Layer: Memory Foam

Combining the support of high quality pocket springs with the comfort of memory foam. People largely beleive that this makes for the perfect combination when picking a mattress. Expect to pay a slight premium, but your body will thank you.

Handles Included : Yes

Have you ever tried moving a mattress that does not have handles? Absolute nightmare, does not matter how strong you are its just a pain. This mattress has handles to make the whole process ten times easier. Recommended considering you should rotate typically your mattress monthly to ensure best longevity

Weight Capacity : 101 Kilogram

This is a heavy product. Consider getting a second person to assist in movement and rotation

Filling Material Composition : Polyester, Memory foam

Polyester is extremely common in mattresses, in fact, almost all mattresses will carry at least some amount of polyester as it will often be used to create a micro-barrier between the top layer and the base layer. Regardless though, what is polyester? Well polyester is simply a synthetic resin that gets spun and used as wadding and fibre fillings. Polyester when used within mattresses is generally described as non-woven and thermally bonded material of polyester fibres to form a mattress sized pad of varying densities and weights. You will typically find polyester in mattresses from low-medium pricing scales, should you start going into very high priced mattresses, you can expect polyester to be replaced with natural fibre.Memory foam is another material composition listed in the specifications for this mattress. Memory foam was developed by NASA back in the 80's and has been used as a comfort layer ever since. Ideal if you want the absolute best in comfort and squishy softness. To be avoided if you find yourself getting too hot in the evening.

Mattress Thickness : 27cm

The industry standard for mattress depth is 7 inches. With most offering a comfortable 10 to 14 inches, so this one at 10 inches is one of the most popular sizes. The higher the load, the deeper it needs to be but a quality mattress in this size can be equally as comfortable and supportive as a deeper budget mattress. 

Number of Springs : 1800

Core Construction: Pocket Sprung

Pocket Springs in mattresses are one of the better constructions. Each spring is housed in it's own pocket within the mattress and helps ensure that all springs stay where they are supposed to and do not drift with time. The main benefit of pocket springs, particular where you have more than 1000 or more springs, is that each spring works independently, contouring to your body and offering unique support across each different pressure point. We strongly recommend pocket spring mattresses where your budget allows over inferior open coil units.

Firmness: Medium-Firm

Medium Firm Tension mattresses suit a lot of people. Slightly firmer than a traditional medium tension mattress, this tension rating is relatively catch-all based on your own preference however, we would say it is perhaps a little too firm for those with a low BMI unless they suffer from back pain. For those, consider a soft-medium or medium, for everyone else, this would be suitable.

Mattress Construction: Core Construction: Pocket Sprung; Top Layer: Memory Foam

The core construction contains individual housed pocket springs. Each spring holds a consistent tension where pressure is applied, reacting independently to provide an even level of firmness across the mattress surface. The personalised support prevents the transfer of movement and "roll-together", relieves pressure point build-up and offer corrective support.   The top layer is temperature-sensitive Memory Foam, in lower temperatures, it’s firmer and in higher temperatures, it’s softer helping to regulate body temperature. Memory Foam moulds to every curve of the body easing pressure points and absorbing excess movement. It is suitable for all sleeping positions and is hypoallergenic, so will help to relieve the symptoms of allergies and asthma.
