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.
