Pursuing “comfortable and pleasant sleep” is a shared goal among all mattress manufacturers,
but the approaches they take differ from brand to brand.
Here, we’ll briefly introduce those differences.
In-store, you can experience each mattress for yourself and receive more detailed guidance.


【Simmons】
Coil Type: Pocket coil mattress
Popular For: Firm and supportive feel
Variety: Wide range from firm to plush mattresses
Price Range: Around ¥60,000 to ¥1,000,000

Simmons mattresses are known for their high coil compression rate, providing strong upward support and a firm sleeping experience.
The hardness of the mattress varies depending on the thickness and length of the coils (assuming the filling material is the same).
The best-selling “Golden Value Premium” (Single size, list price ¥167,400) has become a hit due to its golden balance of moderately firm coils and soft padding.
Mattresses with moderate firmness allow for easy turning with less effort, which also reduces the strain on the lower back.


【Sealy】
Coil Type: PostureTech Coils (connected coils)
Popular For: A gently enveloping sleep feel
Variety: Ranges from firm to plush, often fluffy mattresses
Price Range: Around ¥60,000 to ¥400,000

Sealy’s unique PostureTech coils adjust their responsiveness based on the pressure applied. This helps prevent only the heavier parts of the body from sinking too far, thereby promoting a body-friendly sleeping posture.
All current catalog models feature Polygiene treatment, which is antibacterial and odor-resistant.
Thanks to the embracing feel and increased contact area with the body, these mattresses offer excellent pressure distribution, preventing pressure points and reducing the need to toss and turn.
The superior weight distribution provides a sleep sensation that feels like resting on a cloud.


【Serta】
Coil Type: Pocket coils
Popular For: A plush, resilient sleep feel from gel memory foam
Variety: Ranges from firm to soft, often with a “bouncy” or substantial feel
Price Range: Around ¥60,000 to ¥500,000

The iSeries from Serta (Single size priced from ¥145,800) incorporates gel memory foam, a material known for its excellent pressure relief and thermal conductivity.
These mattresses are characterized by a unique feel that skillfully blends seemingly opposite traits — firmness and softness.
The firmness can be adjusted by altering the length or number of coils (assuming the same filling material is used).


【Annel Bed】
Coil Type: Pocket coils
Popular For: High-quality domestic craftsmanship at an affordable price
Variety: Wide range from firm to soft
Price Range: Around ¥50,000 to ¥180,000

Uses high-strength piano wire blended into the coils, offering increased durability and excellent support for dynamic loads.
The “Micro 3 Zone” model (Single size priced at ¥79,800) provides a plush feel with minimal sinking, making it a customer favorite.
Mattress firmness is adjusted by varying the thickness and quantity of coils (when the filling is the same).


【France Bed】
Coil Type: Connected coils
Popular For: High-quality domestic manufacturing at a reasonable price
Variety: From firm to soft, including high-resilience models with Airweave-style interiors
Price Range: Around ¥35,000 to ¥200,000

Primarily uses connected coils, with variations in the connection method depending on the model.
Some models include “Breath Air,” a material similar in structure to Airweave, built into the mattress.
Mattress and frame sets priced at ¥63,000 are also popular.


【Dream Bed】
Coil Type: Pocket coils
Popular For: JIS-standard highest-quality coils and affordable pricing
Variety: A wide range from firm to soft
Price Range: Around ¥50,000 to ¥200,000

Also available in a narrower “US size” (width 81.5 cm), smaller than a standard single.
Mattress firmness varies depending on the coil type, thickness, and quantity (assuming the same filling material).
