Always use a mattress pad to protect your mattress.
While our mattresses feature a no-need-to-flip design, it is best rotate them head to foot periodically to even out wear.
Body impressions up to two inches are normal and are most noticeable on softer mattresses with thicker comfort layers and king size mattresses. Periodically rotating your mattress from head to foot helps even out body impressions and allows the materials to recover.
Occasionally vacuum the top of the mattress with an upholstery attachment to remove dust.
Spot clean with mild soap and water if needed.
