What to know before buying

Listing details to confirm

The listing gives different pocket-depth figures: the special-feature field says 18 inches, while the feature description claims a fit on mattresses up to 21 inches. Confirm fit against your mattress depth. Allow 48–72 hours in a ventilated area for the topper to expand before first use. The listing says any slight new-foam odor should fade naturally.
