Most mattress care guidance today centers on rotation (and flipping if the mattress is double-sided) to promote even wear. Here’s a practical summary you can use: Direct answer

• For most standard two-sided mattresses: rotate 180 degrees every 3 to 6 months, and flip when weathered or as recommended by the manufacturer. This helps prevent uneven sags and prolongs comfort lifespan.
• For most one-sided (non-flip) mattresses: rotate (head-to-foot) every 3 to 6 months to even out wear.
• During the early “break-in” period of a new mattress, more frequent rotation or flipping is common (every 1 to 2 weeks for the first 1–3 months, depending on the mattress type and seller guidelines).

Context and tips

• Check the care guide: Always follow the manufacturer’s specific instructions, as some models are designed to be turned, while others are not.
• Mattress type considerations:
  • Innerspring and hybrid: typically benefit from regular rotation; flipping may be needed if the mattress is two-sided.
  • Memory foam and latex: usually rotate rather than flip, especially if the top surface has a distinct feel after initial use.
• Practical schedule ideas:
  • If you sleep with a partner, you can coordinate rotations during regular housekeeping days (e.g., every 3–4 months).
  • Use seasonal changes as a natural reminder to rotate.

If you’d like, share your mattress type (two-sided vs one-sided, innerspring vs memory foam/latex) and any manufacturer guidelines, and a tailored rotation schedule can be drafted.
