Flexible Polyurethane foam is used in domestic mattresses owing to its cushioning properties, durability and longevity. They respond to body weight and help in distributing pressure, thus making sleep more comfortable. These mattresses are lightweight and flexible, thus making them ideal for domestic use.
The quality standards of this material have been prescribed by BIS under IS 7933:2022. These foams are checked for density, hardness, compression set, resilience and dimensional stability. Testing of the foams is carried out at BIS-approved testing laboratories to ensure uniform performance and safety of materials. This will ensure that the foam used in domestic mattresses meets the necessary comfort standards. The foam manufacturers must obtain the BIS license to sell their products in the marketplace.
What is IS 7933: 2022?
This is the Indian Standard for flexible polyurethane foam used in domestic mattresses. It mentions the physical and performance requirements to ensure consistent quality, comfort, and durability of mattress foam. As per the BIS (Bureau of Indian Standards), foam for domestic mattresses is:
- Tested for indentation hardness
- Assessed for durability
- Checked for dimensional accuracy
- Evaluated for density and tensile strength

|---|
| Colour Test | Shade and uniformity of foam colour | Ensures consistency in appearance and product uniformity |
| Dimensional Test | Length, width, and thickness of foam | Ensures compliance with specified mattress size and dimensional accuracy |
| Indentation Hardness Test (Characteristic) | Load-bearing capacity and surface resistance | Ensures comfort level and firmness performance of foam |
| Indentation Hardness Index Test | Hardness measurement at specified compression levels | Ensures consistent support and performance quality |
| Durability Test | Resistance to wear under repeated use | Ensures long-term usability and structural stability of foam |
| Density Test | Mass per unit volume of foam | Ensures correct foam density for strength and comfort |
| Tensile Strength Test | Resistance to stretching and breaking | Ensures mechanical strength and material integrity |
| Heat Ageing Test | Foam performance after exposure to heat | Ensures stability and performance under high-temperature conditions |
| Compression Set Test | Permanent deformation after compression | Ensures foam regains shape after pressure removal |
Complete Guide to BIS Approval for Domestic Bedding Foam
The BIS Approval process ensures that the flexible foam mattress material meets the required performance and safety standards. This process is set by the Bureau of Indian Standards (BIS) and includes the following steps:
- Online Registration: Manufacturers register on the BIS Manak portal by submitting company, factory, and product details. Foreign manufacturers must appoint an Authorized Indian Representative (AIR).
- Testing at BIS-Approved Laboratory: Product samples are tested in BIS-approved laboratories for indentation hardness, density, tensile strength, dimensional accuracy, heat ageing, compression set, and overall performance of flexible polyurethane foam used in domestic mattresses.
- Application Submission : The application is submitted along with test reports, technical documents, and factory details. Foreign manufacturers must also submit AIR-related documents.
- Factory Inspection: BIS officials visit and inspect the manufacturing facility to verify the production process, safety measures, and quality control system.
- Grant of BIS License: Upon successful verification of all requirements, BIS grants the certification license under Scheme-I.
- Use of ISI Mark: Once approved, the manufacturer can use the ISI mark on the product with a CM/L number, indicating compliance with BIS standards.
