Mattress Buying Guide in Japan
Choosing the right mattress can make a huge difference in sleep quality, posture, and overall health. With so many types available in Japan—from traditional futons to advanced pocket coil mattresses—understanding the key factors will help you make the best decision.
1. Mattress Type
- Pocket Coil: Individually wrapped springs that respond to your body’s movement and reduce motion transfer. Great for couples.
- Bonnell Coil: Connected coil system offering firmer support, durability, and affordability.
- Foam / Memory Foam: Provides contouring comfort, excellent for pressure relief and body alignment.
- Hybrid: Combines coils and foam for balanced support and comfort.
-
Air Mattresses (High Resilience Foam): Lightweight, breathable, and often portable—ideal for Japanese apartments.
2. Firmness Level
- Soft/Plush: Good for side sleepers who need cushioning at shoulders and hips.
- Medium Firm: Works well for most sleepers, balancing comfort and support.
- Firm: Ideal for back or stomach sleepers who need spine support and less sinking.
3. Thickness
Japanese mattresses usually range from 8 cm to 25 cm. Thicker mattresses offer more cushioning but may be harder to store in small apartments. Futon-style or foldable options are popular for space-saving.
4. Size
- Single (97 × 195 cm) – Common for one person.
- Semi-Double (120 × 195 cm) – Wider than a single, comfortable for solo sleepers.
- Double (140 × 195 cm) and Queen (160 × 195 cm) – Best for couples if room space allows.
5. Breathability & Heat Control
Japan’s humid summers make airflow an important factor. Look for mattresses with 3D mesh, ventilation channels, or breathable foam.
6. Durability & Maintenance
Look for mattresses with recognized certifications such as CertiPUR-US or OEKO-TEX (like the ZINUS model), which ensure safety standards and quality materials. Even without certifications, durability can be extended by using a mattress protector, airing it regularly, and rotating it every few months to prevent sagging.
Frequently Asked Questions (FAQs)
Q1: What is the best mattress type for hot and humid Japanese summers?
A: A breathable pocket coil or an air-flow foam mattress with mesh sides is best, as it prevents heat buildup.
Q2: How long does a mattress typically last in Japan?
A: On average, 7–10 years for good quality mattresses. Budget models may last 3–5 years, depending on usage.
Q3: Should I choose a firm or soft mattress?
A: It depends on your sleeping style—side sleepers prefer softer cushioning, while back and stomach sleepers need firmer support.
Q4: Can I place my mattress directly on the floor in Japan?
A: Yes, many people do. However, ensure proper ventilation to prevent mold buildup, especially in humid months. Using a slatted bed frame or tatami mat is recommended.
Q5: How do I maintain and clean my mattress?
A: Rotate it every 3–4 months, air it out regularly, and use a mattress protector to guard against moisture, dust mites, and stains.
