Sweetnight Island mattress construction
The Sweetnight Island is a 12-inch hybrid mattress built on three main layers: a cooling gel-infused memory foam comfort layer, a transitional polyfoam, and a pocketed-coil support core. Sweetnight positions it as a mid-price alternative to luxury hybrids like the Saatva Classic, with a direct-to-consumer bed-in-a-box delivery model.
Layer-by-layer breakdown
- Comfort layer — 2 inches of gel memory foam. Contours to shoulders and hips without the sink-in feel of traditional memory foam.
- Transition layer — 2 inches of responsive polyfoam. Prevents the "bottoming out" sensation heavier sleepers feel on soft memory foam.
- Support core — 8 inches of individually wrapped coils with a reinforced edge perimeter.
- Cover — breathable knit fabric with cooling phase-change finish.
Who the Island works for
In our testing, the Sweetnight Island scored best for side sleepers between 130 and 230 pounds looking for pressure relief at the shoulder. Back sleepers felt adequate lumbar support, though stomach sleepers and sleepers over 230 pounds reported some sinkage at the hips.
Feel and firmness
Sweetnight rates the Island at a medium-firm 6/10. It delivered slightly softer than that in our tests — closer to 5.5/10 — with noticeable cradle around the shoulder zone. Motion isolation was good thanks to the pocketed coils, and edge support held up for reading or perching at the edge.
Cooling performance
The gel-infused top and cover do their job for average-temperature sleepers. Hot sleepers or those in warm climates may still find the memory foam layer traps some heat; a cooling pad or breathable sheets help. If cooling is your number-one priority, the best cooling mattresses we tested offer stronger heat dissipation.
