The single mattress is the most versatile size in Hong Kong, available in four distinct width and length options to suit everything from a toddler transitioning out of a cot to a teenager who needs more legroom.
At its most common width of 3’0” (91 cm), it fits neatly into compact bedrooms, helper rooms, and standard bunk bed setups.
When choosing between variants, always measure the internal dimensions of your bed frame first. The length matters just as much as the width: a standard single is 6’0” (183 cm) long, while a single long stretches to 6’3” (190 cm) — a meaningful difference for taller sleepers or IKEA bed frames.
Best for: Young children, guest rooms, ultra-compact helper quarters, or narrow built-in loft beds
Best for: Solo sleepers, teenagers, traditional bunk beds, and space-conscious apartments.
Best for: Taller individuals, growing teens, narrow rooms, and European-style frame compatibility
Best for: Active solo sleepers who love extra tossing room, studio apartments, and guest rooms
The most widely accepted standard single mattress size in Hong Kong is 3'0" x 6'0", which translates precisely to 36" x 72" or 91 cm x 183 cm. This size is highly favored locally because it fits seamlessly into compact apartments while offering adequate sleeping real estate for one person.
Yes, solo adults can sleep comfortably on a single mattress, provided they select the correct variant. While a standard 3ft single is fine for individuals under 175 cm tall, we highly recommend taller adults opt for a Single Long (190 cm length) or upgrade to a Large Single (3'6" / 107 cm width) to enjoy extra tossing room and uncompromised legroom.
IKEA bed frames utilize European dimensions, meaning a standard European single frame requires a mattress size of 90 cm x 200 cm (or occasionally 90 cm x 190 cm for select regional styles). A standard Hong Kong single (91 x 183 cm) will fit width-wise but will leave an awkward 17 cm gap at the end. Hush Home can easily customize mattress sizes to ensure a flawless, gap-free fit for any European frame.
The fundamental difference lies entirely in the width. A standard single mattress measures 3 feet wide (91 cm), whereas a Large Single measures 3.5 feet wide (107 cm). Both typically share the standard local lengths of either 183 cm or 190 cm. A Large Single provides roughly 16 cm of additional sleeping surface—making a massive difference for active sleepers.
Absolutely. A standard single mattress (3'0" x 6'0") is the optimal investment size for a child transitioning out of a toddler bed or cot. It provides ample space for them to grow all the way through their teenage years. If your child will be using a top bunk or an elevated cabin storage bed, make sure to pair the frame with a low-profile mattress like our 5" Loft Mattress to satisfy safety rail clearances.
Firmness depends largely on age and sleep style. For growing children and teenagers, orthopedic pediatric experts generally suggest a medium-firm to firm mattress (like our Essence Firm™) to keep the spine correctly aligned during development. For solo-sleeping adults or side sleepers, a balanced hybrid design (like our Hush Mattress™) offers the ideal blend of pressure-relieving surface cushion and underlying structural support.
