Important Recommendation

For High-Density Foam, Memory Foam, and Latex toppers/convertors: We strongly recommend using a Wetsafe mattress protector over these products. Foam and latex toppers cannot be machine washed and must be spot cleaned only. A Wetsafe protector provides essential protection against spills and soiling, extending the lifespan of your topper whilst maintaining hygiene standards.

Sizing Recommendation

Select topper or convertor size to match your mattress dimensions. Choose 190cm or 200cm length based on your bed configuration. Toppers without sides provide lightweight cushioning for individual mattresses. Convertors with quilted sides fit securely over mattresses up to 30cm deep, ideal for joining beds or creating seamless configurations.
