Foam Seating

The best grades of foam for seating applications are High Resilience foams which are available either cut to shape from continuous slabstock foam block or made individually as are cold cure moulded foam cushions.

Slabstock Seats

Slabstock seating grade foams are available in various density's and hardness ranges and colours. The rule of thumb is on the density of the foam for its performance in use. The higher the density the better the performance of the foam and this is reflected on the foam classification the foam is given. Please see our section on foam for further information just click the underlined text for more Foam Grades .

Moulded Foam Seats

Cold Cure Moulded Foam : As above moulded cushions can have different density's and hardnesses to the customers specifications but also the discerning feature of a moulded cushion over a standard foam cushion is one of quality

A moulded cushion has an integral skin which has the effect of creating the greatest strength around the shape of the cushion, the cushion does not loose its shape which in the trade is known as 'sagging or bagging' They keep their shape, their texture and subsequently will last longer.

Our moulded cushions use a High Resilience Polymer which is designed for seating applications and has the ability to create a 'sit in' feel and has a greater durability than standard polyurethane seats.

Recommendations

Whether using slabstock grades or cold cure cushions the one thing to be aware of is not only the foam being High Resilience but also the classification of the foam which should be "V" Classification Combustion - Modified High Resilience Cold Cure Polyurethane Foam: ( V classification very severe ).

The recommended applications for a V class foam are for public transport seats, cinema and theatre seat and contract furniture seating , This foam far exceeds 'S' classification foams ( the standard foam classifications ) as is used in many seat cushion applications. The term High Resilience foam or HR foam refers to the foam’s springiness.

High resilience foam has an irregular cell structure with small and large cell sizes which gives the foam this unique feel. ( In the USA a test that measures the foam’s springiness is performed by determining the percent rebound of a steel ball dropped from a height of 36 inches. The term HR foam refers to a highly resilient foam that will give a very high ‘ball rebound’ reading.)

Also be aware of the foams density. The classifications can be quite broad and a 32 kilo foam that just scrapes a V class may be quite inferior to a 40 kilo foam of the same foam type that easily passes at a V classification.
