Memory foam was developed in 1966 by Nasa’s Ames Research Center to improve the safety of aircraft cushions. The temperature-sensitive memory foam was initially referred to as “slow spring back foam” or "temper foam". It is manufactured by feeding gas into a polymer matrix, the foam has an open-cell solid structure that matches pressure against it and then slowly recovers back to its original shape
NASA released the foam to the public in the early 1980s, but the manufacturing process remained complex and unreliable. In 1991 after much perseverance, a commercial product was released for use as a bed mattress called the “Tempur-Pedic
Memory foam soon saw applications in healthcare to relieve pressure sores. The even distribution of pressure by the foam meant that blood flow was evenly maintained so as to prevent gangrene and sores. The healthcare application also helped overcome one of memory foams initial hurdles as the price points for this next generation foam were frequently much higher than the more common polyurethane foams used in mass furniture manufacture. It became commonly used for wheelchair seat cushions, hospital bed pillows and for patients suffering long term pain or postural problems. By effectively moulding to a patients shape, the foam followed each patients spinal shape and supported them were needed. The heat retaining properties also help some patients with further pain relief from the warming of the associated areas of soft tissue.
As the technology evolved, 2nd generation memory foams began using open cell structures as customers liked the shape forming abilities but not always the warming effects. The Open structure and the addition of gel particles infused into the visco foam gave enhanced breathability and reduced the warming effect. The foams also spring back easier and make them feel softer to the touch, further enhancing comfort.
What will the 4th generation hold? As science and engineering evolves and progresses, so are foam technologies. Our latest product lines incorporate more infusion of innovative materials to push the the science of comfort even further.
Memory Foam is an open cell, flexible polyurethane foam that has high viscosity and high density, but slow recovery. The speed or rate of recovery is controlled by the viscosity and density of the formulation of the foam, so that when it is compressed, the foam conforms to the shape of the compressor and supports it weight. The higher the density, the more the foam softens when body heat is applied, allowing it to mould to a warm body in minutes. These features give memory foam its unique qualities and give it class leading attributes for comfort, vibration and sound dampening and shock absorption.
AeroFoam Industries foam has been uniquely formulated to make it especially suitable for laminating and thermoforming. As the foam recovers its shape, any wrinkles that may form under pressure are slowly pushed back to their original position, avoiding puddling of the seat cover material. The SolaTM range when combined with our leather seat covers, are the only laminated covers in the world to feature our Anti-Wrinkle technology, providing cabin uniformity every time.
The LRGR range also has class leading sound absorption properties. When used effectively, Sola can effectively reduce acute noise levels by 25%, allowing you to create quiet areas of the aircraft or the actual seat. Combined with our composite seating foam design and engineering service, we have created a “sleep zone” in the headrest area that noticeably dampens and noise cancels around the head.
