Serta iComfort review

iComfort is Serta's all-foam premium line and the right pick if you know you prefer memory foam over coils. Serta describes a 5 ZoneResponse design meant to keep the spine aligned, Perfect Conform memory foam to cradle pressure points and a graphite-infused memory foam layer under a CoolFeel cover to move heat away. The standard model comes in five versions: 11.5 inch Firm, 12 inch Medium and Plush, and 13 inch Medium and Plush. Serta's product data on November 10, 2026 listed queens from $1,199 to $1,699, and a Twin XL from $899. The page also says the mattress contains no fiberglass and is 100% USA assembled. Orders from Serta.com ship free and usually arrive in 2 to 4 weeks through RXO Logistics, with a 100-night trial and a 10-year warranty. Hot sleepers who still want foam can compare the iSeries NXG foam models, which add carbon fiber foam at a higher price.
