- NON-SLIP & WASHABLE ZIPPED COVER: The easily removable cover with zipper is machine washable, which means you can wash it regularly and the topper will last longer, avoiding the need of frequent disposal of the mattress topper and waste accumulation. It has four corner elastic straps design which help keep the mattress topper from sliding.
- GEL INFUSED DUAL-LAYER HYBRID MEMORY FOAM TOPPER: The Memory Foam mattress topper provides the perfect balance of softness and firmness thanks to its double-layer structure consisting of gel and supporting foam. Other foam mattresses toppers may be too soft to provide support or too hard to be uncomfortable. This double layer system helps keeping the head rest area soft and supportive, making it suitable for back, side, abdomen and combined sleepers.
- COMFORTABLE SLEEP: Our memory foam mattress topper is designed to provide a better sleeping experience. Its top is hypoallergenic, pain relieving and the cooling texture prevents extra heating.
- BREATHABLE & HYPOALLERGENIC TOPPER: The topper cover is breathable and helps regulate temperature, ensuring a comfortable sleep. It also helps reduce moisture and sweating formation, making it ideal for those who suffer from night sweats.
