4.0 density polyurethane foam is rarely found in residential furniture.
Typically, densities above 2.5 are more appropriate for commercial and institutional use.
- Densities above 2.5 may be found in residential cushions as a thin inner core in a composite cushion.
- This composite cushion could have a central core of ultra high density foam with additional layers of less dense foams and/or feathers/down or fiber.
For polyurethane foams:
- Anything below 1.5 is considered “low-density.”
- 1.6 – 1.7 is considered “medium density.”
- 1.8 and above is “high density.”
Memory foam is different.
- Memory foams are more often found on mattresses than on sofas.
- If a memory is used as part of a composite or non-removable cushion, 4.0 would be a “good” density.
For memory foams:
- Anything less than 4 is “low-density.”
- 4 – 5 is “medium density.”
- 5 and above is “high density.” Densities of 5 and above might be too firm for most seating purposes.
