Sven & Son Signature 14-Inch Medium-Soft Gel Memory Foam Hybrid Mattress, Twin XL, CertiPUR-US Certified, Fiberglass-Free, Made in the USA

The Sven & Son Signature 14-inch hybrid is a medium-soft mattress built in Jacksonville, Florida, that combines gel memory foam comfort layers with an individually pocketed innerspring coil core. The twin XL size measures 38 by 80 inches, the standard length for adjustable bases and dorm and guest beds, and two twin XL mattresses placed side by side form a split king.

The mattress is built in six layers. A quilted rayon and polyester cover encloses an airflow gel layer and a cooling gel-infused memory foam layer that contour to the body and help move heat away from the surface. Beneath them, a comfort support layer adds cushioning over a core of individually wrapped pocketed coils, which flex independently to follow the body's shape, reduce motion transfer between sleepers, and give the mattress a responsive, bouncier feel than all-foam designs. A high-density base foam layer beneath the coils provides the structure of the mattress. The medium-soft feel suits side sleepers and those who prefer a plusher surface.

The foam is CertiPUR-US certified, meaning it is tested for low chemical emissions and made without ozone depleters, PBDE flame retardants, mercury, lead, or heavy metals. The cover is OEKO-TEX certified, and the fire barrier is fiberglass-free.

The mattress ships compressed and rolled in a box. It can be used the same day it is unboxed, and the foam reaches its full shape within 24 to 72 hours, sometimes longer in a cold room. No foundation is required, and the mattress works on a platform bed, box spring, slatted frame, adjustable base, or the floor.
