尺寸 / Sizing (6 Q)
Which size is most popular?
Queen 152×203 cm — 65% of our 100+ HK clients choose Queen. Reason: fits even small master bedrooms (occupies 172 cm wall width × 38 cm wall depth), but sleeps comfortably (same as hotel Queen).
Which wall bed size matches a standard double bed (5 sq ft wide)?
HK standard double bed 152×190 cm = our Queen 152×203 cm (13 cm longer, more comfortable + mattress fits standard Queen size sheets).
small flat < 300 sq ft啱用which size？
300 sq ft or smaller studio / one-bedroom units — most fit a Queen wall bed. If the layout is too narrow for 172 cm wall width, choose Double 137×190 cm (wall width 156 cm) or Single XL 105×200 cm (wall width 124 cm).
What's the ceiling height requirement?
Vertical wall bed: 2.4 m. Horizontal wall bed: 110 cm top-to-bottom space (suitable for old buildings / HKHA). < 2.4 m 一定要揀水affordableWall Bed — 床放低時頭頂得 5 cm 容易撞到。
How much wall depth is needed?
Single 32 cm | Single XL 32 cm | Double 35 cm | Queen 38 cm. This depth protrudes from the wall when the bed is folded up. If you want it flush (level with wall), you need a recessed wall (done during renovation).

試 Sizer → installation / Installation (7 Q)
installation要how long？
Wall bed only 4-6 hours (one day). With two-sided wardrobe 6-10 hours. Full custom 1.5-2 days. All low-noise tools, neighbours won't complain.
How long from deposit to installation?
4-6 weeks production after deposit (Kwun Tong workshop), confirm date 1 week before installation. Total 6-8 weeks. Rush cases 4-5 weeks (priority queue + HKD 2,000 rush fee).
How long is the noisy period on the day?
Truly noisy wall drilling is usually 15-30 minutes (drilling screws into wall). We have a mute drill reducing 60% noise. The rest is frame / hardware assembly (near-zero noise).
Can I install it myself?
Technically yes but not recommended — SBLM mechanism requires on-site tuning (calibrating spring tension to mattress weight) + 5-point stress test, DIY easily goes wrong. Self-install pickup option (HKD -1,500) reduces warranty to 5 years / hardware only. We recommend outsourced installation.
Will it disrupt other renovation work?
If you're renovating: recommend renovator finishes wall surface + pre-marks wall mounting points → we come next day for wall bed installation (4-6 hours). Zero conflict. We have 30+ HK renovator collaboration experiences.
Building lift / corridor protection?
Some property management requires lift protection + corridor floor protection. We coordinate with property management, pay protection fees (if charged), and protect on-site during installation. After completion, we return the lift to a clean state.

Reinstalling within 5 years if moving?

10 yearswarranty之後？
Hardware is still 100% functional (SBLM mechanism design life 25+ years). Free annual check stops. Customers can pay for annual maintenance (HKD 600/visit) or self-maintain — we provide a maintenance kit (HKD 1,200) with 5-year supply of oil + screws.
What if WALLBED KING closes? What about warranty?
SBLM US original warranty is international — even if the HK dealer changes, original spare parts can still be sourced from the US. Our warranty contract is transferable (in case of dealership changes). WALLBED KING has been operating since 2018.
樓型 / approval / Building (7 Q)

Yes. We've installed in 1960s-era Mei Foo / Whampoa / North Point old buildings. Free wall inspection first — red brick / concrete / soundproof cotton walls each have different load-bearing. If reinforcement is needed, HKD +4,800 steel plate + structural engineer certification. SBLM mechanism 700 kg load capacity passes.
Can village houses / villas install wall beds?
Yes. Village houses usually have higher ceilings (2.7 m+), vertical Queen mechanism is ideal. Need village house consent (if shared structure). Standalone houses don't need management approval.
Are newly completed buildings OK?
Most OK! New buildings have higher ceilings (2.65-2.75 m) + new wall structures + strict but clear property management procedures. We have 30+ new building case studies (Lohas Park / Festival Walk / Primavera).
Can rental properties install wall beds?
Requires owner's written consent (wall beds are permanent renovation). Some HK owners agree — because wall beds increase property value by 1.8-3.2% (Centaline 2024 reno-premium data). Worth asking. Short-term rental properties not recommended.
