Savvy Rest’s newest customizable organic mattress is the Zenspring. Made with 8″ of recycled pocketed coils, and one 3″ layer of natural latex, the Zenspring is designed to be both comfortable and durable. We wanted to create an organic mattress option that was more affordable without sacrificing the benefits of customization. Like the Savvy Rest Serenity mattress, the Serenity Spring allows you to choose between Soft, Medium, and Firm layers of Dunlop and Talalay latex.
