Product Description

  • How long to expand?

    24-48h natural expansion. Low temp/humidity may delay but won’t affect durability.

  • Does packaging harm springs?

    No. Pocketed springs + high-resilience foam ensure 8-10 years lifespan.

  • Installation tips?

    1.Unroll with 2 people; 2.Use solid slats (≤5cm gaps); 3.Rotate biweekly first month. Avoid lying 48h.

  • How to measure mattress thickness correctly?

    Measure the center highest point, not edges. Roll-pack edges may be slightly thinner. Use a soft tape on the center after 48-hour expansion for accurate results.
