Questions
What is a Japan-size mattress?
A mattress made to Japanese bed sizes: Single 97 × 195cm, Semi Double 120 × 195cm and Double 140 × 195cm. They’re 5cm longer than Singapore sizes, with different widths.
Will a Singapore mattress fit my Japan-size bed frame?
Not properly. It will be 5cm short and leave gaps at the sides or foot, so it can slide around. Choose the Japan size that matches your frame.
Do Japan-size mattresses come with the 100-night trial?
No. The 100-night trial covers selected mattresses in Singapore sizes only. Japan sizes, bundles and made-to-order mattresses aren’t included.
Can I see them before I buy?
Yes. Most Nuloft mattresses are on display at our Tan Boon Liat and Kaki Bukit Experience Centres, in Singapore sizes. The feel is the same in Japan sizes.
Do you have Japan-size bedsheets?
Yes. Our Nuloft Dreamer, Radiant and Natural Tencel bedsheet sets come in Japan and Singapore sizes. You’ll find them in the list below.
