Harmony Cayman Series – Extra Firm Mattress

Beautyrest® Harmony features new innovations in support, comfort, and cooling working together in harmony to unlock your best sleep. First, we’ve developed a Targeted Support System™ powered by T1 Pocketed Coil® Technology designed to offer additional support where your body needs it most. The T1 Pocketed Coil is placed within the center of the mattress to power the new support system. This patented, dual-stage coil design was invented by Beautyrest® and provides additional support under heavier compression. In addition, we’ve introduced new comfort technologies, including a premium memory foam infused with charcoal that provides natural cooling and pressure relief. The Beautyrest® Harmony collection features HeiQ V-Block™ antimicrobial technology, which is integrated into the fabric cover. HeiQ V-Block™ uses micro-silver and vesicle technologies to attract, break down, and eliminate harmful bacteria, preventing it from impacting the appearance and lifespan of your mattress. Choose from breathable and eco-friendly TENCEL® fabric, or step-up to enhanced cooling with cool-to-the-touch technology within our Emerald Bay Series.

Beautyrest® has also expanded our partnership with SEAQUAL™ to offer their unique sustainable fabric technologies within each Beautyrest® Harmony mattress. Seaqual is a leader in ocean plastic recovery and upcycling efforts, and together this partnership will help promote cleaner oceans with every mattress sold.


Our Targeted Support System™ powered by T1 Pocketed Coil® Technology is designed to offer additional support where your body needs it most.

    Okkkkkkk so this mattress has been a game changer bro, if y’all looking for a good firm mattress and a decent price I recommend it for sure.

    I really like this mattress altough I will say I don’t think it is extra firm like a 9 or a 10 I think it is more like an 8 like the firm o meter says but still the comfort is excellent.

    I was quite surprised at how much I like the comfort of this mattress as I was expecting it to feel like a rock but much better than I anticipated.
