Talalay latex is the Mercedes of latex. Our ULTRA PLUSH latex mattress offers a 6 inch solid Talalay core plus 2 more inches of soft 22 ILD Talalay latex on one side quilted to 1.5" of pure, natural Joma Wool on both sides giving you a choice in firmness depending on which side is up. Add in a beautiful cotton damask fabric and you've got, in our opinion, the finest mattress money can buy. This mattress is 9.5" thick and weighs about 170 lbs. in the king size. Sets include heavy duty Ortho Foundation which offer firm support. Easily compares to Natures Rest by Spring Air, Reflections by Sealy and Serta Latex mattresses however we use no cheap polyurethane on our edges, it's all latex! 20 year limited warranty. 10 year non pro-rated, 10 year pro-rated. This item is not available outside of Arizona due to shipping limitations. Warning! This item is very heavy and NOT recommended for out of state orders due to the difficulties involved if a comfort exchange is necessary. We strongly recommend our Adjustable Ultra Plush Latex Mattress instead. The comfort level is the same but much easier to assemble and exchange if necessary.
