Lucid 3" Gel Memory Foam Mattress Topper with Cover review

Lucid's 3-inch topper is aimed squarely at a mattress that feels too hard. The listing describes three inches of extra plush gel memory foam with aloe, and Lucid says the gel helps pull heat away from the body. What sets it apart from most budget toppers is the cover: a removable polyester cover that goes in the washing machine, which matters for a layer that sits close to you every night. The foam is CertiPUR-US certified, the queen measures 59 by 79 inches and weighs 5.57 lb, and it ships in one box, needing 24 to 48 hours to expand. Walmart.com sold the queen in the gel version for $99.00 when we checked, with free 90-day returns. The plush feel is the limitation: Lucid sells it to make a firm bed softer, not to fix a mattress that has started to sag, and some color variants were out of stock.
