What Is a Foam Compression Recover Time Tester?
A Foam Compression Recover Time Tester is a specialized device designed to measure how quickly foam rebounds after being compressed. It tests the recovery time—the duration foam takes to return to its original shape after pressure is released—which is critical in evaluating foam performance, especially for viscoelastic foam recovery testing like memory foam products.
Core Functionality
This tester compresses foam samples under controlled conditions and monitors their rebound behavior over time. It simulates real-world stress and measures how slow or fast the foam regains its shape, essential for determining product comfort and durability. Unlike static tests, it tracks dynamic recovery, providing detailed insight into foam resilience.
Key Components Breakdown
- Compression Plate: Applies a consistent load to deform the foam sample.
- Displacement Sensors: Accurately measure foam deformation and recovery displacement.
- Timer/Control System: Automates timing sequences and data collection, often PLC-controlled for precision.
- Data Output Interface: Displays and records recovery times and deformation curves for analysis.
These components work together in automated cycles to mimic foam compression and relaxation accurately, ensuring repeatable and reliable results.
Recovery Time vs. Compression Set
It’s important to distinguish between recovery time and compression set—two critical foam quality measures often confused:
| Feature | Recovery Time | Compression Set |
|---|---|---|
| Definition | How fast foam returns to original shape after compression | The permanent deformation or loss of thickness after prolonged compression |
| Measurement Focus | Dynamic rebound behavior over seconds or minutes | Static permanent deformation after load removal |
| Product Impact | Affects comfort, especially in mattresses and cushions | Indicates long-term durability and foam aging |
| Tester Type | Foam Compression Recover Time Tester | Foam Compression Set Tester |
Understanding both helps businesses ensure their foam products meet performance expectations and comply with standards like ASTM D3574.
A Foam Compression Recover Time Tester is essential for manufacturers, suppliers, and quality control teams aiming to validate foam resilience and comfort in various industries such as bedding, automotive, and furniture.

Step-by-Step Guide: How to Use the Derui Tester for ASTM-Compliant Results
Getting accurate foam recovery time data with the Derui Foam Compression Recover Time Tester is straightforward. Here’s how to run ASTM-compliant tests, step by step:
Preparation and Setup
- Calibrate the device: Before testing, ensure the displacement sensor is calibrated for precise measurements.
- Condition foam samples: Follow ASTM D3574 specifications by conditioning foam to the right temperature and humidity.
- Place the foam: Position your foam sample correctly on the compression platen. Secure it to avoid movement during testing.
- Set test parameters: Use the PLC-controlled panel to input test time, compression force, and recovery intervals depending on your foam type.
Running the Test Cycle
- Start compression: The automated foam deformation recovery tester will compress the foam sample at the preset force.
- Hold time: Maintain compression as required by the ASTM standard—this stresses the foam for a specified duration.
- Release and recover: Once the hold time ends, the machine automatically releases pressure. The tester measures foam rebound and recovery automatically with its displacement sensors.
- Repeat if needed: For multiple cycles (like fatigue testing), the Derui tester can repeat compression and recovery sequences precisely.
Interpreting and Reporting Data
- Monitor recovery time: The tester gives a detailed readout of how long the foam takes to rebound after compression.
- Review compression set: Compare recovery time data with compression set results to understand foam durability and behavior.
- Generate reports: Export clear, ASTM-compliant test reports directly from the Derui software, showing all key metrics and graphs.
- Use results in QA: Apply this data to decide if foam meets your quality standards or needs adjustment.
Following these simple steps with the Derui Foam Compression Recovery Tester lets you perform repeatable, standards-compliant foam recovery tests efficiently, ensuring reliable performance for mattresses, furniture, and industrial foam products.
