Here are some practical ways to restore the elasticity of memory foam pillows :
1. Sunbathing Method
Instructions: Air out on a cloudy day on a balcony for 3 hours (avoid direct sunlight! UV rays will brittle the foam).
Principle: Fibers rebound after moisture evaporates.
Note: After sunbathing, gently massage the dented areas with your palms while the pillow is still warm.
2. Freezing Rescue
Suitable for: Pillows that have softened and slumped in summer.
Steps: ① Place in a sealed bag ② Place flat in the freezer for 4 hours ③ Remove and let stand at room temperature for 1 hour before use.
Effect: Low temperature shrinks the foam pores, restoring support.
3. Manual Awakening Massage (for localized sagging)
Technique: → Knead the thinned area like dough → Grasp both ends of the pillow and gently pull in opposite directions → Press the deep indentation with your knuckles in circular motions.
Rhythm: Perform this for 2 minutes before bed every day for 1 week.
4. Rescue for Particle-Filled Pillows
Filling Adjustment: ① Unzip and remove all foam particles ② Sunbathe/dry in a low-temperature dryer for 30 minutes (to remove moisture and fluff up) ③ Reduce the amount of foam particles when repacking. 1/5 of the filling (overfilling actually makes it feel compacted)
5. Ineffective home remedies to avoid:
| Bad Method | What Really Happens | Safer Fix |
|---|---|---|
| Boiling in water | Melts foam into clumps | Steam iron 12 inches above fabric |
| Machine washing | Shreds the foam | Vacuum with dust mite attachment |
| Heavy weights overnight | Crushes structure | Books pressing <2 hrs |
6. Signs of Expiration (Time to replace)
Pressing and rebounding for more than 10 seconds, still leaving deep dents
White cracks appear after folding (sponge aging)
Emitting a sour smell (sweat stains penetrate and cannot be removed)
