Materials & Care

Your mattress is handcrafted from all-natural materials, so it needs a little extra care to settle properly. Regular rotation and flipping lets the materials settle evenly, prevents body impressions and extends the life of the mattress.

  1. Rotate 180° (head to toe).
  2. Flip (side to side).
  3. Rotate 180° (head to toe) again.
  4. Flip (side to side) again.

First year: rotate and flip monthly. After the first year: every two to three months.

With a LETTO topper: rotate and flip only the topper every few weeks at first. After a couple of cycles, begin rotating the mattress as well, then add flipping the mattress to the routine.

Warranty: 10-year limited warranty covering manufacturing and material defects. If an issue arises, LETTO will repair or replace your mattress as needed.
