Spindle deliberately doesn’t use glue in its mattresses because it wants to maintain adjustability and make it easier (and more affordable) to ship its mattresses and for customers to move them around. While Spindle’s motivation for not using glue isn’t to avoid toxic chemicals, the fact that these mattresses are glue-free is a bonus to customers who do have concerns over adhesives. The latex layers are created as single, solid, blocks, then cut to size. This means there is no need for seams or glue. Even the King Size mattress has three solid layers of organic latex. This makes it much easier to move the mattress from room to room or to a new home. The King Size mattress weighs more than 180 pounds, with all three layers in place; clearly, being able to pack and move each layer individually is very helpful. This layered design also makes it easier and cheaper for Spindle to ship the mattresses which, in turn, keeps the mattresses affordable and within reach for more customers.
