ViscoSoft Rescue Hybrid Lux Mattress Topper review

The Rescue Hybrid Lux uses two layers with separate jobs, which is why it works well at 4 inches. On top, a box-quilted TENCEL Lyocell cover holds 470 grams of fiberfill per square meter, made with ADVANSA Eco Origin fiber from recycled bottles. Under it sits CertiPUR-US certified gel-infused memory foam that ViscoSoft says keeps the pillow-top from flattening onto the mattress. An 18-inch elastic skirt pulls over the bed like a deep-pocket sheet, and the cover comes off for the washing machine. ViscoSoft pitches it at owners of a firm mattress rather than a sagging one. The 4-inch twin was $169.95 on sale when we checked, against a regular $219.95, and the store also advertised 15% off when you buy two toppers. It carries a 90-day money back guarantee and a 5-year warranty, and the page showed a 4.6 average from 2,409 reviews. Some reviewers there mention a foam smell and warmth.
