- How thick is it, and will sheets still fit?
- It is 3 inches of memory foam plus 1.5 inches of fiber, about 4.5 inches total. Use deep-pocket sheets; standard sheets may pop off.
- Is it good for a firm mattress?
- Yes. The foam core softens a firm or worn mattress and adds pressure relief. Very soft mattresses may become too soft.
- Does it sleep hot?
- The fiber top helps airflow, but memory foam can still feel warm. Hot sleepers should weigh that before buying.
- How do I set it up?
- Unroll it on the mattress and let it expand for up to 24 hours. Air it out first if there is a foam smell.
- How often should I replace it?
- Expect one to three years of nightly use. Replace it when the foam stays compressed or no longer springs back.
- Is it machine washable?
- The fiber layer and cover may be washable on a gentle cycle; check the care label. The foam core should only be spot cleaned.
