The list of Ultimate Hybrid product lines and models can assist in your online searches as well as be printed and brought into the store with you.
Asking for these products by name will ensure that your local mattress retailer can direct you to an "official" Ultimate Hybrid to evaluate.
The Ultimate Hybrid Mattress™ is offered by many of the world's leading mattress brands in a variety of styles and price ranges. At the "core" of every Ultimate Hybrid is Comfort Core™ technology by Leggett & Platt®, which sets them apart from other hybrid-style mattresses.
So if you're shopping for an Ultimate Hybrid, ask your salesperson which mattresses feature Leggett & Platt's Comfort Core.
