Latex is one of the most durable products in the mattress industry. It provides unbeatable support and comfort without the sinking feeling. The Ultimate Dreams Total Latex Mattress from DreamFoam Bedding is a unique latex mattress that allows you to customize and change the comfort level or firmness of your mattress. The hard thing about buying a mattress is the uncertainty of getting the correct comfort. With the Ultimate Dreams All Latex Mattress, we allow you customize the comfort level before your purchase, but then allow you to exchange the latex in the mattress if the bed after delivery if it is a little bit too soft or firm. There is a fee ociated with the exchange. The mattress starts with a 6Ó Talalay 36 ILD core. We can subsute the core of the mattress for a 32 ILD latex core or a Natural Dunlap latex core for no extra charge. Above the latex core is our zipper cover. This cover allows you access to the comfort layer latex. This latex is what we exchange if the mattress is to firm or soft. The denser the latex the firmer the mattress will feel. The total thickness of the mattress is about 10 inces thick. The Ultimate Dreams Total Latex Mattress also uses an organic wool to meet the federal fire retardant guidelines. This allows us to offer a bed with fewer chemicals as compd to many of our compeors. Combine the organic wool with the adjustable comfort layer and a made in the USA product and you have one of the best values you can find in the mattress industry.
