Casper Onyx 2.0 Queen Mattress with Head Up Only Base

Based on our expertise with adjustable bedding, elevating the head can be highly effective for reducing snoring and managing symptoms of acid reflux. By using the wireless remote to raise the head of this mattress, you can use gravity to help keep airways open and prevent stomach acid from rising, leading to a more restful and uninterrupted night's sleep.

Yes, this mattress is a reliable choice for health-conscious households. The foams are CertiPUR-US certified, meaning they are manufactured without ozone-depleting chemicals and are regulated by the Consumer Product Safety Commission. Additionally, the mattress has been tested for low VOC (Volatile Organic Compound) emissions—measuring less than 0.5 parts per million—to ensure better indoor air quality for your bedroom.

Absolutely. This queen-sized mattress features standard dimensions (80"L x 60"W), while the RTG Sleep 2900 base has a low-profile 4-inch height. This compact base design, paired with the 10.5-inch mattress height, provides a modern, streamlined look that doesn't overwhelm smaller rooms. Since the base fits within most standard bed frames or can stand alone on its legs, it offers great versatility for urban living spaces where maximizing square footage is essential.

This mattress set includes the RTG Sleep 2900 adjustable base, which allows you to raise the head of the bed using a wireless remote. This feature is ideal for those who enjoy reading, working on a laptop, or watching television in bed, as it provides ergonomic support without the need for extra pillows. By elevating the torso, you can find a more comfortable upright position that reduces neck strain compared to a traditional flat foundation.

The mattress is engineered for optimal airflow to ensure you stay comfortable throughout the night. It features two specialized layers: Breathe Foam for consistent air circulation and Breathe Flex Foam, which provides responsive support while allowing heat to dissipate. This combination pairs breathability with softness, making it an excellent choice for sleepers who want to avoid the heat retention often associated with traditional foam materials.

This mattress is designed for long-term durability using a firm Casper Core base. This foundational layer provides the structural integrity needed to support the upper comfort layers while specifically preventing the sinking and sagging that can occur with lesser-quality foam beds. The addition of a "waterfall edge" border style also helps maintain the mattress's shape and aesthetic over years of use.
