Evolution of coils
The History of the Mattress Coil
Decades of research and development proudly deliver the world’s most advanced spring systems.

FIVE TURN DOUBLE OFFSET
The basic coil design used widely in the market in 1969 was the bonnell coil, an hourglass-shaped coil with a round head and foot and (usually) five turns. The coil was knotted at the head and foot to provide stability.
In 1969, Sealy developed and introduced the “Double Offset” coil. By offsetting or flattening the sides of the coil head, two benefits were derived. Coils could be positioned more closely, giving more points of support, and a smoother hinging action between coils was made possible, providing smoother conformance to the body and resulting in more restful sleep.

SIX TURN TRIPLE OFFSET
Sealy further developed the offset coil design by adding an extra turn to provide more working wire for durability while offering a more responsive, conforming coil.
The third side of the coil was offset, or flattened, to allow better edge wire attachment for greater sleep surface and the ability to add more coils to a spring unit if required.

SEVEN TURN TRIPLE OFFSET
This coil took the benefits of the six turn triple offset coil and further enhanced durability and conformance through the addition of a seventh turn.
Seven turns meant an even more responsive and durable coil. Combining the triple offset head design allowed more coils for the surface area, providing better support and increased conformance to improve pressure relief.

POSTURETECH®
The PostureTech® coil heralded a completely new approach to engineered support.
The core performance characteristic of this design was its ability to “Sense and Respond” better than its predecessors. The ability to provide a variable rate of response to load was part of the Posturepedic® performance criteria from the start and this advancement took it to a new level.

DUAL SUPPORT SYSTEM
In 2001, Sealy introduced the most revolutionary coil in the industry with its Crown Jewel Posturepedic® range. This coil’s design comprised two parts.
The head and foot of the coil were designed to micro-conform to the shape of the body at rest. This was called the SynerFlex Surface and provided a transition from conformance to support unrivalled in the industry.
The inner core of the coil was based on Sealy’s famous PostureTech® coil, with its ability to sense the load applied and respond with correct support. This provided better muscle relaxation, pressure point relief and consumer value than other support systems.


REST™ TI COIL
This coil was a further development of the one-sided coil principle designed specifically for single-sided mattresses. Comprising three phases, it provides a seamless transition from the comfort layers to the deep down Posturepedic® support.
The three phases are:
• SynFlex surface at the top of the coil
• Initially flat helix angle at the inner coil
• Steeper and firmer helix angle at the base of the coil.
ReST™ coils are aligned in alternating columns to increase stability.

Support system typically have all coils aligned in the same direction.

RESTSUPPORT™ TI COIL
Sealy’s most advanced coil technology – RestSUPPORT™ – uniquely provides three stages of support:
• 1st Stage – The unique SynerFlex surface micro-conforms to relieve pressure points.
• 2nd Stage – The upgraded Align Head design is softer at first and more supportive deep down to provide better contouring and Posturepedic® support.
• 3rd Stage – The Posturepedic® innercore is designed to sense the load applied and provide the orthopaedically correct response.
It is made with Titanium alloy for extra strength and long-lasting
performance.

ALIGNSUPPORT™ TI COIL
Sealy’s unique AlignSupport™ Coil Technology is an intuitive two-stage coil system that senses your weight and responds with the support needed to help maintain your body’s natural alignment.
It leads to:
• 6% improvement in deep down support
• 75% reduction in lateral movement
• 18% reduction in motion transfer

What People Say About Sealy Mattress
Winnie
Very happy with the recommendation of Carol Ng at Millenia Walk. Her detailed explanation has helped me make the right decision on a suitable mattress. Thank you.
Esther C
I went in search of mattress as my present one gave me aches and leg cramps. Decided to try Sealy so went to a few outlets to try their mattresses. Had a wonderful experience at Isetan Sealy as Mr Frankie Wong assisted and was very patient in explaining and shared on the different mattresses. Had a great experience from trying the different types and finally purchasing from this outlet. Thank you Frankie for your advice and help!
Linda Ang
Purchased my Sealy mattress from Jess from BHG Bugis. Throughout the whole process, Jess was very patient in understanding my needs when it comes to purchasing a mattress which suits my needs. To be very honest Sealy mattresses are not cheap 😅 But the materials used in its mattresses in providing a good sleep is there. I would say that investing in a good mattress for enhancing one’s sleep is a wise choice. Not only a mattress is important in one’s sleep, external factors such as surroundings, weather, daily life activities such as work etc plays a part too.
James
Fantastic experience with Philip Chin. He provided his professional advise on what mattress for us to choose on based on our budget.

I would like to extend my sincere appreciation to Irene Ng and Philip Chin from Sealy Isetan @Serangoon for their exceptional service. Both displayed remarkable patience and a consistently outstanding attitude throughout our interaction. They took the time to understand my needs and went above and beyond to ensure I received the best possible deals. Their professionalism and dedication truly made a difference, and I’m grateful for the excellent support they provided.
