You may find that your foam is a little firm at first – this is perfectly normal and your foam will soften gradually during initial use to give you longer lasting durability. All foam can lose up to 20% of its volume during the first few months of use - this is quite normal and not a fault.
Are you aware the firmness levels in foam decreases in the summertime? This is called Summertime ILD regression and is a natural characteristic of foam and not a fault.
Once foam is exposed to air, it will start to yellow in colour. Again, this is a natural characteristic of foam and not a fault.
Don’t forget, foam used in upholstery and seating will require regular dressing and plumping. This redistributes the filling and ensures the interiors fill the covers to the correct shape.
