What does the cooling gel infusion do, and will it keep my mattress cooler?

Cooling gel is blended into the foam to help draw heat away from your body and regulate sleep temperature. The open-cell foam structure and ventilation channels also promote airflow for a cooler sleep experience than traditional memory foam.

Is there an odor when it arrives, and how long until I can sleep on it?

A mild new-foam scent is normal and fades quickly. Unroll in a ventilated room for 24–48 hours. By the time it fully expands, the smell should be gone.

Will my current sheets still fit?

Measure your mattress plus your topper height before ordering sheets to ensure a snug fit. The added height may require deep-pocket sheets (15"+ depth).

Which thickness is right for me — 2", 3", or 4"?

The 2" adds subtle softness to a slightly firm mattress. The 3" delivers deeper pressure relief for back and side sleepers. The 4" is ultra-plush, ideal for very firm or worn mattresses.

Can I wash this topper?

The foam can't be machine washed. Spot clean with mild detergent and a damp cloth. We recommend pairing it with a waterproof mattress protector to keep it fresh long-term.
