We purchased a split king Naturalux mattress with the 6" Dunlop Core and the 3" talalay topper with organic cotton cover. Very happy with the mattress which is well made and comfortable. Pricing was excellent and Ken was a pleasure to work with. He was very informative, answering any questions that I had while researching latex mattresses. The mattress arrived on time. I would definitely purchase through Arizona Mattress again.
