Who it fits

Key specs explained for this mattress

Size: Queen

This dimension measures 60 inches wide by 80 inches long. It fits standard Queen bed frames and sheets. You get ample surface area for two sleepers without overwhelming a small bedroom. If you share your bed, this width allows comfortable movement. It is the most common size for couples seeking balanced space and stability.

Firmness: Medium Firm

This rating indicates a balanced feel that is neither too soft nor too hard. It provides enough cushion to relieve pressure on your shoulders and hips while keeping your spine aligned. You benefit from this if you sleep on your side or back. It offers a stable surface that prevents sinking too deeply into the mattress layers.

Thickness: 14 in

The mattress stands 14 inches tall from the floor. This height includes the foam comfort layers and the coil support core. You can easily get in and out of bed without straining your knees. It also provides a substantial, premium look on your bed frame. Thinner models may lack the same depth of cushioning and support structure.

Mattress Construction: Hybrid, coil-and-foam

This build combines pocketed coils with foam layers. The coils provide responsive support and help air circulate through the bed. The foam adds pressure relief and contours to your body. You avoid the heat retention common in all-foam beds. This hybrid approach balances the bounce of springs with the comfort of foam for versatile sleep support.

Design and build details

The VISCOFLEX 14 inch medium firm Queen mattress uses a hybrid construction, combining pocketed coils with premium foam layers. According to the listing, this coil-and-foam design creates an open structure that promotes continuous airflow. You benefit from better temperature regulation compared to all-foam alternatives. The medium-firm feel targets spinal alignment, offering targeted support where you need it most. Hundreds of high-compression springs adapt to your body’s curves, while reinforced industrial-grade steel helps the springs hold their shape over time. This setup aims to deliver pressure relief and balanced comfort for all sleep positions.

In terms of physical dimensions, the mattress measures 60 inches wide by 80 inches long and stands 14 inches tall. It weighs 112 pounds, which is typical for a Queen-size hybrid. The color is listed as Navy Blue. The model number is P2503221. These specific measurements ensure compatibility with standard Queen bed frames and sheets. The 14-inch height provides a substantial profile, which may influence how high you sit on the bed when getting in and out.

The materials are certified by CertiPUR-US and OEKO-TEX, and the listing states the product is fiberglass-free. This means you do not need to worry about off-gassing or chemical exposure from fiberglass components. The certifications indicate that the foams meet strict standards for content, dispersion, and absorption. You can expect a sleep surface that prioritizes safety and durability. The design focuses on providing a stable, breathable foundation for restful sleep without relying on potentially harmful materials.

Setup and daily use details

This mattress arrives compressed and boxed. You unroll it onto a standard Queen frame, which measures 60 by 80 inches. The unit weighs 112 pounds, so you may need help moving it into place. The 14-inch height fits most standard bed frames and requires sheets designed for deep pockets. Allow the foam and coils to expand fully before sleeping on it. The hybrid construction ensures it remains stable once expanded. You can use it with adjustable bases if your frame allows for the 14-inch profile. The medium-firm feel provides a balanced surface. The pocketed coils adapt to your body curves, offering targeted support. This design helps maintain spinal alignment for side, back, or combination sleepers. The open coil structure promotes airflow, which helps regulate temperature during the night. You do not need to rotate the mattress regularly, as the industrial-grade steel springs are built to hold their shape. The CertiPUR-US and OEKO-TEX certifications indicate the foams and fabrics meet strict safety standards for low emissions. There is no fiberglass in the cover, which simplifies cleaning and maintenance. You can spot clean the surface with mild soap and water. The 365-night trial lets you adjust to the firmness level. If the balance feels right, you keep it. If not, you can return it within the year. The 10-year warranty covers structural defects. The motion isolation feature reduces disturbance when you move, creating a quieter sleep environment for partners.

Before you buy this hybrid

You need a sturdy Queen bed frame to support the 14-inch height and 112-pound weight. This hybrid mattress requires a slatted base with gaps no wider than three inches to prevent sagging. Standard Queen sheets fit the 60-by-80-inch surface, but deep-pocket sheets may be necessary due to the thick profile. The medium-firm feel works well for most sleepers, but you should compare it against the 10-inch options if you prefer a lower profile. The coil-and-foam construction promotes airflow, yet you might still want breathable bedding to maximize comfort. Clean spills immediately with a mild detergent and cold water. Avoid harsh chemicals that could damage the CertiPUR-US certified foam. This model sits alongside other hybrid choices, offering distinct lumbar support. You should verify your frame’s weight limit before placement. Proper ventilation helps maintain the open coil structure. Check your existing bed skirt height to ensure it clears the 14-inch edge.

Check before you buy

• Verify bed frame slat spacing is under three inches.
• Ensure frame weight limit exceeds 112 pounds.
• Confirm deep-pocket sheets fit the 14-inch height.
• Check that existing bed skirt clears the edge.
