Thalassa is our premium top-mattress, crafted with grace by our passionate carpenters. It is completely metal-free and suitable for all body types. It combines the health benefits of seaweed with the elasticity of natural latex for a relaxing, high quality sleep experience. The luxurious, plush cover is padded with a thick layer of extra fine cotton for additional softness and an elegant touch. The zipper opening allows easy maintenance and a longer lifespan. Finally, our personal tip: Combine Thalassa with the Proteas mattress or the Triton bed-mattress for the ultimate sleep experience. Available in 4 colors (white, grey, petrol blue & brown)
