Spring Mattresses - Bonnell Spring & Pocket Spring


Bonnell Spring Mattress
The Bonnell spring is the classic Spring Unit, and has, through the years, proven its worth. It is made from around hourglass shaped springs which are tied together to form a mat. A round helical crosswise connects each single spring to a spring unit.

Different thickness (gauge) of wire in the springs makes a harder or softer mattress. The lower the gauge, the firmer the mattress. The number of springs per mattress type is one of the key quality characteristics of a bonnell spring mattress.

Pocket Spring Mattresses
Pocket spring mattresses contain pre-stressed springs inserted into individual fleece or cotton pockets and then clipped among one another or glued on top, middle or bottom. It is the point-by-point elasticity that distinguishes itself from others. The greater number of springs allows more flexibility so that the mattress can better mould to the body shape.

This type of mattress is generally considered as the best that spring units can offer and is normally the most expensive type of product. It is higher priced because manufacturing is more complex.

Latex Mattresses


Superior support and pressure relief Latex is one of the most ergonomically sound of all mattress materials.Once you spend the night on a latex mattress you will wonder how you ever slept without one. Latex automatically conforms to your body, providing superior support and pressure relief. No more aching back caused by insufficient support, no more aches and pains caused by inadequate pressure relief.

Naturally therapeutic Latex mattress is naturally therapeutic that assures optimal orthopedic support in any sleep position. It dynamically conforms to your body, offers a natural alignment of the spine,supporting the shoulder and hip area, without pushing against pressure points

Most widely recommended Latex mattresses are the most widely recommended mattresses. Continuously recommended by Orthopedic Surgeons and Chiropractors because of the extraordinary comfort and the unparalleled orthopedic support . Latex is renown for gently co-forming contour to every part of your body.

The bed has a 100% latex core, can be covered with organic cotton and wool quilted to a beautiful natural unbleached, undyed damask cotton mattress fabric. The absence of metal parts avoids creating interference with the natural electromagnetic flows within the body.

Luxurious comfort and resilience Body perspiration is quickly dissipated and passed out of the mattress, keeping the user in luxurious comfort.Best choice for someone with a partner that moves around too much. Latex is extraordinarily resilient, recovers quickly and dampens the movements without disturbing the sleeping partner.

What is Latex?


Environmentally friendly
Latex is an environmentally friendly biodegradable natural product derived from a rubber tree - the hevea brasiliensis. Once extracted and processed to make a foam is poured onto a mould to create a mattress base. Therefore a latex mattress contains no spring system, is similar to foam beds, but natural.

The natural foam latex contains no toxic substances or any man made chemicals - including no petroleum based chemicals, no formaldehydes, no benzene, no fire retardant chemicals, and emits neither fumes nor ozone.

Hypoallergenic nature
Due to its hypoallergenic nature, latex is the perfect mattress material and recommended for those with allergies, eczema, hey fever, asthma and respiratory problems

Durability and resilience
It is the most durable cushioning material available (3-4 times as durable as polyurethane foams Bacteriostatic) and very resilient therefore the need to turn it over is avoided.

Latex cell structure
The latex cell structure contains millions of interconnecting cells which provide self-ventilation with every movement you make.The cells let out the hot air and moisture transmitted from the body and take in fresh air from the surroundings thus body perspiration is quickly dissipated and passed out of the mattress, keeping the user in luxurious comfort.

The unique pattern of 350 small pin hole cavitations per square foot on both sides makes the hardness characteristics of the mattress isotropic, therefore ensuring that the surface is uniform and provides maximum comfort.

Thermal Properties
Latex's thermal properties are truly outstanding. Its superior cell structure gives it maximum breath-ability, keeping you cool in the summer and warm in the winter.

Spring vs Latex


Hypoallergenic nature
Due to its hypoallergenic nature, Latex is the perfect mattress material and recommended for those with allergies, eczema, hey fever, asthma and respiratory problems. Spring mattresses and foam beds contain materials with chemical compositions that are intolerable by such individuals.

Superior support
A spring mattress pushes up to support your body. Latex mattress dynamically conforms to you, offers a natural alignment of the spine,supporting the shoulder and hip area, without pushing against pressure points therefore providing superior support. They feel denser while helping to relieve the pressure points of the body.

Evenly distributed body pressure
On a latex mattress you'll notice that your body pressure is evenly distributed to the natural contour of the body, allowing deeper, more restful undisturbed sleep. No more aching back caused by insufficient support, no more aches and pains caused by inadequate relief.

Tossing and turning
As pressure is is more evenly distributed on a latex mattress, pressure on pivotal areas on the body is reduced thus preventing circulation cut-offs. Circulation cut-offs normally cause an interruption normal sleep by inducing tossing and turning.

Luxurious comfort
Its superior cell structure gives it maximum breath-ability, keeping you cool in the summer and warm in the winter.
Body perspiration is quickly dissipated and passed out of the mattress, keeping the user in luxurious comfort.

Noise & Disturbance
Natural Latex Foam Mattresses unlike Spring Mattresses do not make noise when moving in sleep or cause any disturbance to the sleeping partner.

Retains shape - Resilience
Unlike a spring mattress, a latex mattress retains its shape and does not sag or deform. No need to turn over through out the life of the mattress.When you move in the bed, you don't feel lumps as it comes back to it's original shape quickly.

Sleeping on a memory foam mattress, creates body impression in the mattress taking a while before it goes back to shape. Customers describe sleeping on a foam mattress as "sleeping on jello" and "quicksand" as it feels very lumpy.

Best choice for someone with a partner that moves around too much
Latex is extraordinarily resilient, recovers quickly and dampens the movements without disturbing the sleeping partner . Its inherent resilience cannot be matched by synthetic versions.
