The Island is a hybrid mattress from Sweet Night that pairs gel-infused memory foam with individually pocketed tempered steel coils and high-density edge foam. It rates a 6.5 out of 10 on firmness, aimed at heavier sleepers and couples who wake each other. The quilted knit cotton cover zips off. Against all-foam rivals it adds coil support and better edge stability; against premium hybrids it is a simpler build with fewer comfort layers. Owners rate it highly, with most praise going to motion isolation and back support.

Owners rate the Island very highly, with couples and heavier sleepers saying it cuts motion transfer and holds up their backs. A few lighter side sleepers find it firmer than expected.
This hybrid mattress combines gel-infused memory foam with individually pocketed tempered steel coils. The gel memory foam adds comfort and a cooling effect. The pocketed coils move independently, which isolates motion between partners.
High-density foam gives edge-to-edge support and resists sagging and rolling. The outer pocket coils are reinforced for edge support, so sleepers are less likely to slide off the side. The firmness is 6.5 out of 10.
The mattress has a soft, zippered, quilted knit cotton cover. The foam is CertiPUR-US certified. It arrives compressed and rolled in a box.
