The problem they had
The clients are a couple in their early 30s, both professionals working from home 2-3 days/week. They moved into their 2-bedroom 380 sqft Tin Hau flat in 2024. Initial setup: standard queen bed in master + sofa-bed in living room for occasional guests.
By late 2025, three tensions emerged:
- Master bedroom felt cramped. The queen bed (137×190cm footprint) consumed ~30 sqft daytime. The room had no daytime function beyond walking through to the wardrobe.
- Sofa-bed past its life cycle. 3-year-old sofa-bed showed bowing springs. Hosting parents 2-3 times/year had become uncomfortable for everyone.
- Future kid considerations. Couple plans to have first child within 2-3 years. They didn't want to renovate the second bedroom now (as nursery) and again in 5 years (as toddler room) and again at age 10 (as kid room). Three renovation cycles = HKD 80-150k wasted.
They considered three alternatives before reaching us:
- Upsize to 500 sqft flat: Reviewed listings for 6 months; HKD 7,400/month rent delta = HKD 444,000 over 5 years. Rejected as too expensive vs the value gained.
- Standard renovation of master: Quoted HKD 80-120k for built-in cabinets + space optimization, but didn't solve the daytime-floor-space problem.
- Sofa-bed replacement: HKD 12-18k for new sofa-bed but didn't address the master bedroom issue, and 5-year cost (replacement + medical) was projected at HKD 22-30k.
What we installed
Configuration:
- Queen vertical wall bed (152×203cm)
- Häfele Pro Series gas-piston hardware (4,500-cycle test rating, 5-year warranty)
- Floor-to-ceiling cabinets both sides of bed (light oak finish to match flat's existing wooden floor)
- 200mm pocket-spring mattress (queen size)
- Soft-close hinges + child safety locks (for future use)
- LED strip lighting integrated into cabinet headboard
Why this configuration:
- Queen (not Double): clients are a couple — same footprint when stowed, but 30% better sleep quality at 17 sqft per person vs Double's 12 sqft per person
- Vertical (not horizontal): 2.6m ceiling supports vertical comfortably, and clients prefer the standard mattress depth
- Floor-to-ceiling cabinets both sides: maximizes storage while bed is stowed, replaces existing wardrobe
- Light oak finish: matches existing wooden floor + complements white walls

Client quote
"We didn't realize how much daytime space we were missing. Now the master feels like a real living-and-sleeping space. The mechanism is genuinely effortless — my wife was nervous about operating it, but after one try she was confident. Best HKD 53k we've spent on the flat." — Couple, Tin Hau (anonymized with consent)
The outcome (6 months post-install)
Following the install, we checked in with the clients quarterly. As of 6 months post-install:
- Daily use: Couple deploys the bed nightly, stows in the morning. Total time: ~12 seconds for full deploy + stow cycle daily. No issues with mechanism.
- Daytime use: Master bedroom now serves as a yoga + reading space (yoga mat stored in side cabinet). Wife works from home in the second bedroom; husband sometimes works at the dining table. The daytime master is also where they entertain visiting friends informally.
- Hosting: They hosted both sets of parents over Christmas weekend; second bedroom + sofa-bed combo accommodated everyone. Couple comments that the new arrangement was "100% better than the previous setup".
- No mechanism issues. 6 months in, gas piston still smooth. Cabinet finishes show no wear. Soft-close hinges working perfectly.
- Future plan: When they have their first child (planned within 2-3 years), they'll install a Single XL wall bed in the second bedroom (estimated HKD 38-42k). Same Häfele Pro Series hardware. Future-flex from infant to teen, same frame.
