The lift door opening is the real limit, not the bedroom size. It measures 90cm wide by 209cm tall, and that’s where the mattress stops dead. You get a Queen at 152cm wide, but forget the angle. You’ll need to turn it sideways. Most people measure the bedroom, forget the lift already.

Orthopaedic units are heavy. High-density foam and firm pocketed springs don’t bend easily like a budget foam. If you buy one online, the delivery team must carry it up. Staircase carrying happens for older blocks. That adds a surcharge, lah. Don’t assume free delivery covers everything. Most free delivery kicks in around a $200–$300 spend where lift access exists.


Megafurniture’s Somnuz® line is engineered for this. They know the lift dimensions. The team checks the corridor turn before they load the bed. A flexible mattress can bend into a lift a rigid frame can’t. This one crucial.

Setup matters too. A firm orthopaedic mattress needs a solid base to work. If the slats are too wide, the support breaks. Leave 60cm clearance on the exit side. The delivery guys will test the door before they push the cart. You want the structure intact.
" width="100%" height="480">Mattress delivery and setup: Checklist for ensuring proper supportA Queen mattress measures 152x190cm and fits most HDB master bedrooms comfortably. Leave around 60cm clearance on the exit side for easy movement. Standard length is 190cm across all local bed sizes. This dimension suits stomach sleepers requiring firm support without overcrowding the room significantly. Space planning is vital for comfort.
