The COSMOS Upsilon is a 15cm deep memory foam mattress designed in Ireland, originally developed for the luxury hotel industry and now available directly to consumers. The 7-zone support system targets the head and neck, shoulders, back, waist, buttocks, legs, and feet independently, distributing body weight more evenly than a single-density foam mattress and helping to maintain natural spinal alignment across all sleeping positions.

The dual-sided construction is a practical feature that extends the mattress lifespan and adapts to seasonal changes. The winter side uses thick AloeTouch double stretch fabric for a warmer, body-hugging feel, while the summer side features VISCOGEL ACTIF foam for a cooler, more therapeutic rest on warm nights. The mattress is OekoTex certified, confirming that the materials used meet strict standards for harmful substance content.

The high-density foam core provides the pressure relief and adaptability associated with memory foam, and the padded euro top with embroidered stitching adds a layer of surface comfort. The mattress arrives vacuum-compressed and rolled in a box for easy delivery and setup. It requires 72 hours to fully expand after unboxing before use.

Available in a wide range of sizes from single through to super king, and in multiple depth options from 15cm to 32cm. A 5-year warranty is included. This listing is for the 90 x 190cm single at 15cm depth.
