Tempur mattresses must always be placed on a ventilated bed base e.g., with springs or slats, or a platform topped unit on castors, legs, or feet to allow air to circulate freely, preventing moisture from accumulating.
Tempur Material itself cannot be washed, sponged or dry cleaned. There is a high risk that soaking with water or other cleaning fluids will cause irreversible damage, destroying the benefits of comfort and support which the unique Tempur Material provides.
Most Tempur items have covers that may be carefully removed for cleaning or just for airing, allowing you to freshen up your product. A label stitched inside the cover will give you specific care instructions for the item you have purchased.
As a general rule of thumb, if your mattress has Tempur Material embedded or quilted into the cover, while it may be removed for airing, it is not washable.
