Borealis Gel Mattress

The Borealis is a 9-inch euro top gel foam mattress made in Canada. The cooling knit fabric on the surface works with a calm cooling gel layer below to manage heat, while the bio soy foam core provides long-term support. Available in Twin, Double, Queen, King, and RV Short Queen (60×74). Need it to fold for a sofa bed, camper or cabin bench? Choose the bifold custom cut option above the add-to-cart button: enter up to three section lengths or just the total length, and we confirm every measurement by phone before cutting.

How the Borealis Actually Sleeps

The 9-inch euro top design gives the mattress a quilted surface feel without a separate pillow top that can shift or lose its shape over time. Euro tops are sewn flush with the sides of the mattress, which makes them more durable than traditional pillow tops. The premium cooling knit fabric on the surface works with the calm cooling gel layer below to manage heat. Like any gel foam mattress, it sleeps cooler than standard memory foam, though not as cool as a pocket coil system with open airflow channels. If temperature is your primary concern, compare this with our coil-based cooling options from our mattress collection.

The bio soy foam base provides long-term support with a lower environmental footprint than conventional petroleum-only foam. The full mattress is compatible with adjustable bed bases. Take the mattress quiz if you want a quick read on whether the Borealis fits your sleep profile before visiting.
