Below are the frequently asked questions. If you have other questions, you may enquire with merchant here: Enquire with Merchant


1. What are the standard local mattress size?
Single 91x190cm
Super Single 107x190cm
Queen 152x190cm
King 182x190cm

2. Is it difficult to find bedsheets for thicker mattresses?
Most bedsheet suppliers/retailers produce ‘deep drop’ sheets as most premium mattress brands are promoting plush top/ticker mattresses.

3. Does a mattress need to be firm in order to provide support?
The support comes from the innerspring. The comfort layers determine the level of comfort which should embrace you to sleep.
Our mattresses feature an advanced and durable innerspring designed to deliver spinal support. You choose the mattress that feels the best for you, and you will receive the support you need.

4. What is the difference between innerspring and form mattress?
Innerspring mattresses feature tempered steel coils in a variety of configurations. Layers of upholstery provide insulation and cushioning between your body and the spring unit.
Form core mattresses use either latex or visco-elastic memory foam cores as the support system.

5. What is body impression?
Different types of comfort layers conform to the shape of your body so as to provide support and relieve pressure points, thus providing a restful night sleep. All comfort layers naturally conform to your body shape hence the mattress displays body impression. It is recommended that you rotate the mattress every 3 months to minimize severe body impression.

6. When should I change my mattress?

  • You wake up with aches and pains
  • You sleep better on other beds
  • Your mattress shows visible signs of overuse
  • Mattress edges are no longer supportive
  • Mattress and bed base create noise when you toss/turn
  • Your current mattress is 7 years or older

7. Why does the mattress sag?
Several factors can cause the mattress to sag, including an improper bed frame. Using proper bed frame with proper center support greatly reduces the chances of mattress sagging.

8. How should I protect my mattress?

  • Use a mattress pad or protector will help to avoid stains
  • Rotate the mattress to promote even wear
  • Use a quality quality bed frame
