Wall Bed vs Platform Bed vs Tatami: Which Is Most Space-Saving for Hong Kong Nano Flats?

2026-06-22 Published · Wallbed by Design

Hong Kong nano flats, studio units, and even 300 sq ft small flats all face the same challenge: the bed takes up half the room. Three mainstream space-saving sleep solutions — wall bed (Murphy bed), platform bed, and tatami — each have their fans, but "most space-saving" depends on several dimensions. This article breaks down each honestly to help you choose the right solution for your unit.

First, let's clarify: what are the three?

• Wall Bed (Murphy bed) — The bed body uses a hardware mechanism to fold up vertically against the wall or into a cabinet, freeing up floor space when not in use. By day it's a living room or study; by night it's a bedroom.
• platform bed — A custom wooden platform raises the bed, with drawers or flip-up panels underneath for storage. The bed is fixed and cannot be folded away.
• tatami — A Japanese-style low platform with tatami mats/mattress, close to the floor, some with flip-up storage. Simple, affordable, but involves sleeping on the floor.

Item-by-Item Comparison Table

★ Ratings are relative; actual results vary by unit size, ceiling height, and carpentry quality. Prices are based on Hong Kong custom work; free on-site measurement before quoting.

Dimension 1: Space-saving — Wall bed wins on "time flexibility"

Many people think "space-saving" only means how much space the bed itself takes up. But in a nano flat, the real key is how many different uses one patch of floor can serve throughout the day. Platform bed and tatami bed spaces are "permanently occupied" — after getting up in the morning, that area is still a bed. You can't do yoga there, can't set up a desk to work, and kids can't play there.

The wall bed is different: when folded up, nearly 100% of the floor is freed. An 80 sq ft sleeping corner can become a study, living room, or children's play area during the day. For nano flats under 200 sq ft, this "one room, multiple uses" flexibility effectively "expands" the usable area by 30–40%.

Dimension 2: Storage — Platform bed wins

If your main pain point is "nowhere to put things" rather than "nowhere to move", the platform bed is the storage king. The entire platform underneath is drawers or flip-up panels — suitcases, seasonal clothing, and miscellaneous items all fit inside. Tatami also has flip-up storage but with smaller capacity. Wall beds have limited built-in storage, but you can add custom tall cabinets on both sides — though total capacity still usually can't match a full-room platform.

Dimension 3: Hong Kong humidity — floor-level solutions need caution

Hong Kong's humid season sees summer humidity above 80% for days. Platform beds and tatami are close to the floor with poor underneath ventilation, making them high-risk spots for mould, dust mites, and even bed bugs. Regular airing, dehumidification, and inspection are needed. When a wall bed is folded up, the mattress sits vertically against the wall with air circulation and off the floor, so humidity risk is relatively lower — but we still recommend a breathable bed frame and keeping the room ventilated. This should be considered during the renovation planning stage, not after mould has already appeared.

Dimension 4: Renting vs owner-occupied

For owner-occupied properties, all three work — it just depends on whether you prioritise space-saving or storage. For rentals, check the modification terms: platform beds and tatami are mostly custom carpentry; removal leaves marks and is hard to restore, so landlords may not accept them. Wall beds have freestanding cabinet systems that require no wall drilling, can be fully moved out, and leave no large holes — making them the most tenant-friendly. Before signing, discuss clearly with your landlord which modifications are reversible. See our wall bed rental flat guide for details.

How to choose? Three scenario routes

1. Nano flat / studio + want daytime activity space → Wall bed. One floor, two uses; maximum space-saving flexibility.
2. Lots of belongings + don't mind bed permanently occupying floor → Platform bed. Unbeatable storage capacity.
3. Very tight budget + okay with sleeping on the floor → Tatami. Most affordable, simplest, but requires diligent ventilation to prevent mould.

If you want a wall bed's space-saving but worry about insufficient storage, you can actually combine "wall bed + custom tall cabinets on both sides" to solve both at once. During our free on-site measurement, we'll calculate the actual usable area and storage capacity with you — no guessing.

Our free on-site measurement

Before any quote, we provide a free on-site measurement (30–45 minutes):

• Measure unit dimensions, ceiling, and candidate walls
• Calculate exactly how much floor a wall bed frees when folded up
