Questions & Answers

  • What size is a king size mattress topper?

    150 x 200cm (5ft x 6ft 6in)

  • What are the benefits of using one?

    By serving as an extra layer, a king-size mattress topper enhances not only comfort but also acts as a protective shield, effectively extending the lifespan of your mattress by shielding it from the wear and tear of daily use. Consequently, using one can significantly improve the feel of your mattress, elevating both comfort and support.

  • What is the typical lifespan of a king-size mattress topper?

    For those who use their topper nightly, we suggest replacing it every 3–4 years. If you use your topper less frequently, you may not require a replacement as frequently.

  • Should I use sheets or a mattress protector with my king-size topper?

    If you have both a mattress topper and protector, the recommended order for your bedding is as follows: Mattress, Mattress topper, Mattress protector, Fitted or Flat Bed Sheets.
