Who it fits

Grbsy 16-Inch King Key Specs

Thickness: 16 in

This mattress stands 16 inches tall, which is 4 inches taller than the common 12-inch standard. You get a deeper comfort layer that cradles your body more fully. This extra height provides greater pressure relief for side sleepers and those who prefer a plush, cloud-like feel. It also makes bed sheets easier to put on, as the deeper pocket fits the bulkier profile without slipping off the corners.

Mattress Construction: Hybrid

This model combines a pocketed spring base with memory foam layers. You get the supportive bounce and airflow of coils alongside the contouring comfort of foam. This mix helps regulate temperature better than all-foam beds, which can trap heat. It also offers better edge support, allowing you to sit or sleep near the perimeter without feeling like you will roll off.

Firmness: Medium Firm

The medium-firm balance offers a stable surface that supports your spine while cushioning your pressure points. This level is versatile, working well for back and stomach sleepers who need alignment, as well as side sleepers who need shoulder and hip relief. It avoids the sinking feeling of soft beds and the hardness of firm options, making it a safe choice for couples with different preferences.

Comfort Layer: Cooling gel memory foam

This layer uses gel-infused foam to draw heat away from your body. You will stay cooler throughout the night, which is critical for heat-sensitive sleepers who often wake up sweaty. The gel helps regulate the temperature of the memory foam, preventing the traditional heat-trapping issue. This feature works with the breathable Euro-top to keep your sleep environment fresh and comfortable all night long.

Support Core: Pocketed spring base

The base uses individually wrapped coils to provide targeted support and motion isolation. Each spring moves independently, so when you toss and turn, your partner feels less disturbance. This core also enhances airflow through the mattress, aiding the cooling system. The pocketed design ensures the springs adapt to your body shape, maintaining spinal alignment and reducing pressure on sensitive areas like the lower back.

You can use it the same night, though full expansion may take slightly longer. The 16-inch height requires a standard king bed frame. Ensure your foundation supports the 105-pound weight and the hybrid construction. The reinforced edge support foam and edge-responsive coils help maintain stability when sitting on the perimeter. This design maximizes usable sleeping space and reduces sagging under normal use.

Daily use involves interacting with a medium firm feel. The 7-zone ergonomic support targets different body areas. The individually zoned pocket springs contour to your shoulders and hips while providing lumbar support. This alignment helps keep your spine neutral throughout the night. The 1000+ pocket springs isolate motion. If your partner moves, the springs absorb that movement. You experience minimal disturbance. The airflow design promotes heat dissipation. Gaps between pocket coils create natural air channels. The cooling gel memory foam and graphene-infused fabric regulate temperature. This combination helps heat-sensitive sleepers stay cool.

Copper ions and charcoal in the high-density foam help absorb odors. This creates a hypoallergenic sleep environment. The 365-night trial allows you to test the setup and daily comfort.

Before You Buy This Mattress

You should verify your bed frame supports a 16-inch profile. The 105-pound weight requires sturdy slats or a solid base to prevent sagging. This hybrid mattress fits standard King frames, but check your headboard clearance. The 16-inch height may interfere with some adjustable bases or low-profile frame designs. You will need deep-pocket sheets that accommodate the extra thickness. Regular rotation helps maintain even wear across the medium firm surface. The cooling gel memory foam and pocketed springs work together to manage temperature. If you sleep hot, this design prioritizes airflow through coil gaps and breathable fabrics. Compare this 16-inch model to the 14-inch option if you prefer a lower profile. Ensure your bedroom doorways can accommodate the rolled box delivery. The fiberglass-free construction means you can skip special fire safety checks, but the CertiPUR-US certification confirms foam safety. This choice suits those needing deep pressure relief alongside structural support.

Check before you buy

• Verify frame supports 16-inch height and 105-pound weight.
• Confirm deep-pocket sheets fit the extra thickness.
• Check headboard clearance for the tall profile.
• Ensure bedroom entry allows box delivery access.
