Foam Density Tricks Of The Trade
Many particularly comfortable foam-upholstered chairs will combine two layers of foam, a softer top layer over a firmer lower layer.
For a more cushioned, less boxy appearance, the softer layer can also be wrapped around the sides of the firmer lower layer.
In some lounge chair cushions, foam is cut up or shredded, giving a sitting experience more similar to sitting on feather-filled upholstery.
Foam And Fire Resistance
Most foam produced in the world today is, for obvious reasons, constructed to a standard that allows it to be categorised as ‘Fire Retardant’ (FR). In the UK, where our fire rules differ from even those of the European Union, foam used in upholstery is typically specified as CMHR (Combustion Modified High resilience), which is more resistant to fire than FR foam - see also our blog: Hospitality Furniture Fire Safety Regulations for more information. When upholstery is tested for fire resistance in the UK, the foam under the upholstery is always CMHR foam.
Making the right choices about foam can be tricky, so please do get in touch with us for more information about this or any hospitality furniture requirements you have.
