Who it fits

Key specs for this hybrid

Size: King

This size measures 76 inches wide by 79.9 inches long. You get ample space to move without disturbing a partner. It fits standard king bed frames and sheets. Choose this if you share your bed or prefer extra room to stretch out. It is wider than a queen, which helps couples sleep more comfortably.

Thickness: 12 in

The mattress stands 12 inches tall from the floor. This profile provides enough layers for comfort and support without looking bulky. It pairs well with standard bed frames and headboards. You get a substantial feel without the heaviness of thicker models. This height is common for hybrid beds that combine coils and foam.

Firmness: Medium

The bed offers a balanced feel that is not too soft or too hard. This rating suits side, back, and stomach sleepers equally well. It cushions pressure points like hips and shoulders while keeping your spine aligned. If you like a plush top but need support, this firmness level is a practical middle ground for most sleep positions.

Mattress Construction: Hybrid foam and pocket coils

This build combines comfort foam with a support core of individually wrapped coils. The foam contours to your body for pressure relief. The coils provide bounce and airflow. This mix helps prevent the sinking feeling of all-foam beds. It also reduces motion transfer, so you are less likely to feel your partner move during the night.

Design and Build Specs

The listing describes a hybrid build that pairs individually wrapped coils with cooling gel-infused memory foam. This combination targets spinal alignment and pressure relief. The comfort layer contours to your body, while the support core provides structure. You get a medium firmness rating, which the brand notes suits side, back, and stomach sleepers. The cover is a breathable knitted fabric designed to promote airflow. Inside, open-cell foam layers work with the gel foam to reduce heat buildup. The foam is CertiPUR-US certified and fiberglass-free, according to the listing. This construction aims to keep you cool and supported throughout the night.

This king size mattress measures 76 inches wide by 79.9 inches long and stands 12 inches tall. It weighs 91 pounds. The model color is listed as black, with a gray finish on the 12-inch version. These dimensions fit standard king frames and sheets. The bed ships compressed in a box. You unroll it on your floor, and it expands over 72 hours. The boxed design makes it easier to move through tight spaces or apartments. You do not need special delivery equipment. The pocketed coils isolate motion, which helps couples sleep without disturbance. The breathable materials help manage temperature for hot sleepers.

Setup and Daily Use Guide

This mattress arrives compressed in a box. You will need to move it to your bedroom. The listing notes it is ideal for apartments or tight spaces because of this packaging. Once you cut the packaging, the bed begins to expand. You should allow up to 72 hours for full expansion. During this time, the foam and coils adjust to their final shape. The unit weighs 91 pounds, so you may need assistance lifting it onto your frame.

It fits standard king bed frames. The dimensions are 76 inches wide by 79.9 inches long. You should use sheets designed for king sizes to ensure a proper fit. The 12-inch height sits comfortably on most platform beds or adjustable bases.

Daily use involves sleeping on a medium firmness surface. The individually wrapped coils reduce motion transfer. This means you likely will not feel a partner moving during the night. The cooling gel-infused memory foam and breathable knitted cover promote airflow. This helps regulate temperature while you sleep. The CertiPUR-US certified foams and fiberglass-free construction ensure safe everyday contact. You can use the bed immediately after unboxing, though full comfort may develop as it expands. The medium firmness targets spinal alignment for side, back, and stomach sleepers. This setup requires no tools or complex assembly. You simply place it on your frame and wait for it to reach its full 12-inch thickness.

Before You Buy This Hybrid

You will need a sturdy, flat foundation to support this 12-inch hybrid. The listing specifies it fits standard king frames, but you should verify your slat spacing is no wider than three inches. This prevents sagging in the individually wrapped coil support core. Keep the area clear for expansion. The mattress expands fully within 72 hours, so ensure you have enough floor space in your room. You may want a waterproof protector to maintain the CertiPUR-US certified foam’s integrity. Cleaning requires spot treatment only; do not flip the bed. This model sits alongside 1 other options in our guide. It suits those who prioritize cooling gel-infused memory foam and motion isolation. If you prefer a firmer feel, consider the 14-inch variations listed. Check your bedroom door dimensions before delivery, as the boxed unit weighs 91 pounds. Ensure your frame can handle the 12-inch height for easy entry and exit.

Check before you buy

• Verify slat spacing is under three inches.
