HDB lift door opening is the real limit at roughly 90cm wide by 209cm tall. You must leave a 2–5cm buffer when manoeuvring bulky bed frames through the corridor. Check internal doorway sizes before purchase so you won't face costly returns. Megafurniture offers in-store support for measuring your specific flat layout.
Queen size frames measure 152x190cm and fit most HDB master bedrooms comfortably. Leave around 60cm clearance on the exit side for easy movement and access. Standard HDB doors measure about 91.5x213cm, so you'll ensure the frame pieces pass through. This dimension check prevents delivery headaches in tight corridors.
