10 Year Warranty

The Miralux III by International Bedding has the strong-but-flexible LFK innerspring unit, a very strong edge support, a gel lumbar area and a non-prorated warranty. One of the most supportive firm mattresses that we carry, it's sure to become a best seller to those looking for one of the firmest mattress models available, who'd like to experience some luxury features at a lesser cost.

The Miralux III is 13 inches thick and features a Tencel fabric cover that is naturally breathable, hypoallergenic and biodegradable. For a cooler sleep surface and a durable, firm build, it's a great choice.

Miralux III - Luxury Firm Mattress

I like a very flat, firm and supportive mattress and if you do as well, this may be the model for you. I love the Tencel cover - it keeps a cool feel due to its breathability. Tencel is also a better fabric for someone like myself who has allergy problems.

The Miralux III is a very heavy model with an extremely strong edge support. While the difference isn't felt as much in firmer models, the LFK coil system is a bit more flexible than most types of innerspring units.

In terms of overall value, the IBC "Miralux III" is a definite winner. Your luxury features are here (gel lumbar, Tencel cover, LFK innerspring, non-prorated warranty, attractive design) but the luxury price tag is not. I strongly recommend this model to those seeking a high quality firm mattress.
