Hydraulic bed frames offer the largest storage capacity of any bed type, typically holding 300–500 litres underneath the mattress. This volume suits HDB residents needing to store bulky luggage or off-season clothing without separate storeroom space. Gas-strut mechanisms lift the base smoothly, ensuring it's easy access without compromising the compact footprint of a 12 sqm bedroom. Buyers can check the storage bed collection at Megafurniture showrooms to verify fit before purchasing.
