Whether you're a busy office worker, someone who sits for long hours, or simply a person who wants to rest properly at the end of the day — waking up with a sore back and scattered focus throws off your whole day.

- Convert units carefully to avoid buying the wrong size
- Many international brands adjust to Taiwan sizing for the local market
How to Choose the Right Mattress Size: Four Key Considerations
Choosing the perfectly sized mattress is a key step toward better sleep and a better life. It's not just about length and width on paper — it takes a hard look at your habits and your space. These four aspects will help you make the smartest choice:
- Sleeper build and count
- Length should exceed the sleeper's height by 15–25 cm
- Width should exceed shoulder width by at least 40–50 cm
- Sharing with a partner, kids, or pets? Allow extra space
- Room size
- 3–4 ping: fits a standard double
- 5–7+ ping: fits an extended or extra-large double
- Leave 40–50 cm of walkway beside the bed
- Bed frame fit
- The mattress must match the frame's inner dimensions
- The frame's inner dimensions should be 2–3 cm larger than the mattress
- Personal sleep habits
- Frequent tossers and sprawlers need a wider surface
- If you read or use a laptop in bed, consider going up a size
Mattress Size and Room Area
Mattress size directly affects how spacious a bedroom feels and how you move through it. Suggested pairings:
- Standard single (3 ft): at least 2–3 ping
- Extended single (3.5 ft): at least 3 ping
- Standard double (5 ft): at least 4 ping
- Extended double (6 ft): at least 5 ping
- Extra-large double (7 ft): at least 6 ping
Always measure the room before you buy, and leave room for wardrobe doors, nightstands, and everyday movement.
Budget and Mattress Lifespan: The Key to Smart Spending
Budget matters when choosing a size. Generally, bigger mattresses cost more — but a mattress is a long-term investment, lasting 8–10 years or longer. Cradle of Life uses China Steel high-carbon steel pocket springs and premium Thai natural latex, materials that boost support and durability and make good sleep a more economical, lasting pleasure.
Combining ergonomic support with natural materials, the Heritage Collection and Formosa Series come in sizes from single all the way to extra-large double, so every family and every room can find the right fit. From floor plan to sleep position, these collections have a size that matches your life.

Mattress Size FAQ
Q1: My mattress doesn't exactly match my current bed frame. Can I keep using it?
A1: If the gap is slight, mattress straps, non-slip pads, or widened frame edge guards can fix sliding and support issues — no need to replace the frame right away. If the gap is large, adjust the frame or switch to a better-fitting size for safety and durability.
Q2: My room is small. Are there space-saving ways to set up a bed?
A2: Consider storage bed frames, lift-up beds, frames without headboards, or platform and tatami-style bases to maximize space. These setups add storage or shrink the furniture footprint — great for small bedrooms.
Q3: My height falls between two standard sizes. How do I choose?
A3: Go by your sleep style. If you curl your legs or sleep on your side, the standard size is usually enough; if you tend to stretch out or lie flat, choose the longer mattress so cramped posture doesn't disturb your sleep.
Q4: My partner and I have different routines (night owl, restless sleeper). What size should we choose?
A4: Start from a 5-ft double or larger, or use a split setup — two single mattresses side by side. Pocket spring construction further dampens motion transfer, helping you avoid disturbing each other.
Q5: Do sheets and protectors have to match the mattress size exactly?
A5: Yes. Beyond length and width, check that the fitted sheet can fully wrap the mattress's height. Stretch and pocket depth vary by brand, so measure your mattress's thickness before buying and choose sheets that won't slip or come loose.
Rebalance Your Life, Starting With a Good Bed
The right spatial setup buys you deeper rest
Choosing the right mattress size was never a small matter. It decides how you lie down each night and how you wake each morning — and whether you're willing to truly give "rest" back to yourself.
At Cradle of Life, we believe good sleep isn't luck — it's insistence on the details of a mattress: materials, support, breathability; size, structure, craftsmanship. Every step has to stand up to time and to your body.
True comfort lives in the details
There are plenty of mattresses on the market, but what we care about most is this:
Can you truly relax, truly stretch out, and truly sleep well on this bed?
Built around comfort and durability, Cradle of Life selects TENCEL® covers, premium Thai natural latex, and China Steel high-carbon steel pocket springs, paired with breathable structures and non-toxic processes.
Only when a mattress's size, support, and materials fit together does sleep move from "rest" to "recovery" — letting you wake up with that light, restored feeling.
That's why we build mattresses for every size and sleep-position need: every room, lifestyle, and body is different, and what you deserve isn't settling — it's a true fit.
But no amount of studying specs beats the second you actually lie down — your body will tell you straight away whether this is the one.
A mattress is a zero-distance daily essential; your back, shoulders, and waist are more honest than any product description.
So we warmly invite you to visit a Cradle of Life store and try one for yourself.
Feel the rebound of the materials, the steadiness of the support, the difference in firmness — and find the bed that best matches you and your family.
We guard your sleep with expertise; your body will answer with comfort.

FAQ
What size is a standard double mattress in Taiwan?
A standard double is 5 x 6.2 Taiwanese feet, approx. 152 x 188 cm — suitable for couples, married partners, or a single sleeper with room to spare. An extended double is 6 x 6.2 ft (approx. 182 x 188 cm), and an extra-large double is 6 x 7 ft (approx. 182 x 212 cm), better for taller sleepers or anyone who wants more space.
How big should my room be for each mattress size?
As a guide: at least 2–3 ping for a standard single, 3 ping for an extended single, 4 ping for a standard double, 5 ping for an extended double, and 6+ ping for an extra-large double (1 ping is about 3.3 m²) — plus 40–50 cm of walkway beside the bed. Always measure the room before buying, leaving space for wardrobe doors and nightstands.
My partner and I have different schedules and the tossing wakes me. What size should we get?
Start from a 5-ft double or larger, or go with a split setup of two singles placed side by side. Pocket spring construction further reduces motion transfer so you don't disturb each other. Choose a length 15–25 cm beyond your height and a width at least 40–50 cm wider than your shoulders — and the more people sharing the bed, the more space you should allow.
