Product Description

The G4 Nova Luxury’s 12-inch luxury mattress profile cradles you on a confidently firm surface that feels welcoming. 

A breathable cooling luxury cover woven from Tencel ® and infused with Aloe Vera wicks heat and is naturally hypoallergenic, so even sensitive sleepers relax sooner. 

Beneath the cover, open-cell memory foam technology combines iDeal Air Adapt® Memory Foam and iDeal Thermal Gel Reactiv® Foam; together they deliver targeted pressure-point relief while channeling warmth away for a noticeably cooler night’s rest. 

Because of this layered design, your spine enjoys maximum spinal alignment support from an Ultra HD AirFlow high-density core, helping back and stomach sleepers wake without stiffness. 

Moreover, the build is adjustable-base compatible memory foam, arrives as a mattress in a box for fast USA delivery, and carries an iDealBed 10-year manufacturer warranty plus our 120-night risk-free sleep trial.

Best Purchase Ever!!!

My back, neck, & shoulders are a train wreck from yrs of wear, tear, & more than my fair share of falls. I FINALLY broke down & bought myself a firm mattress & man oh, man what a difference!!

Awesome mattress

This mattress took exactly what the directions said about 24 hours to completely expand, the firmness is perfect. I am a side sleeper and also sometimes a back sleeper and I can say this is great for me!

STILL EARLY

I've only had this mattress about a week. So far, it is very comfortable. I have had some of the best
deep sleep I have ever had. We'll give it a little more time but so far, I am happy with this purchase.
I thought it might be a little too hard for me, I can only sleep on my sides but I have not had any
issues yet.
