Product Description

The iDealBed G4 Nova Luxury Memory Foam Mattress greets you with a cloud-like medium soft feel that invites deep, restorative sleep. 

This 12-inch medium soft memory foam mattress blends plush pressure relief with reliable alignment so side and combination sleepers wake up refreshed. 

A top layer of open-cell gel memory foam paired with advanced heat-dissipating cooling technology draws away warmth for all-night temperature balance. 

Beneath, a high-density support foam base steadies the spine, while transitional foams absorb motion so couples enjoy undisturbed sleep. 

Moreover, the breathable circular-knit Tencel™ cover (infused with soothing Aloe Vera) wicks moisture and remains naturally hypoallergenic. 

Because of this thoughtful stack, shoulders and hips feel cradled yet buoyant, easing back- and shoulder-pressure concerns. 

As for some peace-of-mind perks, there’s a 120-night risk-free sleep trial and 10-year non-prorated warranty provide sleep trial and warranty coverage. And, free shipping USA nationwide gets your new retreat to your door without any hassle.

SUCH A GREAT MATRESS!

I have had my mattress for about 8 months now. Seriously it is the best!!! I sleep so much better with this mattress compared to our other Casper mattress that was 3x the price. It's just the right amount of soft and firm. I will definitely buy again for other rooms.

It really good!

Was on the fence on this mattress but it’s not bad at all. Actually really nice. Some said it’s firm. The one I have you actually sink into it a bit and it’s comfortable. I will recommend this.

Amazing

It took me a long time to decide on this mattress. Looked at so many. I needed one that was between 8-12 inches and 60-80lbs.
This one expanded to the expected 11 inches. Very comfortable without being too soft. No smell at all.
