Construction
This model's name doesn't encode its materials, and we haven't tested it in our lab.
For construction detail, start with the Sweetnight brand hub or our mattress types guide, which explains how foam, latex, hybrid, and innerspring builds differ in feel and durability.
Sweetnight signature technology
- Flippable Dual Firmness: Medium-firm on one face and plush on the other, so a firmness mistake is fixed by flipping the bed rather than returning it.
- Gel-Infused Memory Foam: Gel beads in the comfort layer to moderate the heat build-up typical of dense budget foam.
- Zoned Pocketed Coils: Coil units on the hybrid models with firmer coils through the centre third for lumbar support.
