Hi Steph,
Post #29 here includes some of the local “possibilities” and includes a link to a post with the closest factory direct manufacturer to you as well.
Latex is certainly a high quality and very durable material and would make a good choice for those who wanted a more “fast response” feel and as long as the combination of the firmness/softness levels of the support core (either latex, innerspring, or polyfoam depending on budget and preferences) and comfort layers were suitable for your needs and preferences. While memory foam in higher densities (5 lbs and up) and high quality HR polyfoam (2.5 lb density and higher with a high resilience and sag factor) can also be “high performing” and durable choices for a comfort layer (the upper layers are usually the “weak link” of a mattress) … latex has a long history of being the most durable of all the foam types.
