Hi Rydray1,
Just so you are aware … most people with latex allergies will be fine with a latex mattress depending on the type of allergy. The foam that is made from latex has had the allergens (the surface proteins) removed for the most part unlike other latex products like gloves or condoms or other solid rubber products. There is more about latex allergies in post #2 here.
Of course you may still prefer other materials but for the most part … those with the more common type IV latex allergies will generally be fine with a latex mattress so at least it may still be an option.
