Small acts of kindness, like creating the Pacific Seaqual mattress, support our dedication to the environment. Our luxurious Pacific Seaqual mattress is made from natural raw materials (plastic waste collected from the Mediterranean Sea). High-quality polyester thread and recyclable resources are used to create the textiles. We protect the environment and your sleep in this way. This mattress has the SEAQUAL TM certification, which ensures that the textiles used in its construction are comprised of premium polyester thread created from recovered marine debris. For added comfort, the Pacific Seaqual mattress has a pocket spring core made of individually packaged springs. Additionally, due to its high density, this mattress is more durable and the ViscoAqua substance keeps the temperature of the mattress up to 3 degrees cooler than with traditional viscoelastic foam.
