KELTFOS Full Size Mattress 12 Inch - Soft Cooling Gel Memory Foam Hybrid, Medium Plush for Pain Relief & Deep Sleep, Fiberglass-Free, 100 Night Trial

Product Overview

This KELTFOS mattress measures 75 inches long by 54 inches wide by 12 inches thick, fitting standard full-size bed frames. It weighs approximately 52 pounds, though some reviewers report around 58 pounds, making it manageable but heavy for one person. The three-layer construction includes a gel memory foam comfort layer, high-density foam, and pocket springs. The cover is a breathable polyester blend that wicks away moisture. It arrives compressed in a box, double-wrapped in plastic with clear unrolling instructions. Users should place it in its final position before cutting the inner plastic, then allow 24-48 hours for full expansion. The medium-plush firmness is described as soft yet supportive, ideal for side and combination sleepers. Care instructions include ventilation, steam cleaning for stains, and using vinegar and lemon for odor neutralization. The mattress works with adjustable bed frames, though it may initially resist bending without body weight. Variants are not specified, but the model PT-FU indicates this full-size option.

Design & Build

The KELTFOS Full Size Mattress features a 12-inch hybrid design with three distinct layers. The top layer is gel-infused memory foam that contours to the body and regulates temperature. Below it, a high-density foam layer adds durability and support. The base consists of pocketed coils that provide responsive bounce and edge reinforcement. The cover is made from a breathable polyester blend that wicks moisture and promotes airflow. This construction aims to balance soft comfort with firm support, targeting pressure points like hips and shoulders. The mattress arrives compressed in a box, double-wrapped in plastic to protect during shipping. A cutter tool and instructions are included for safe unrolling. Users should place it on the bed frame before cutting the inner plastic to control expansion. The design emphasizes motion isolation, with coils that work independently to minimize partner disturbance. Reinforced edges prevent sagging and increase usable surface area. Aesthetics are simple, with a neutral cover suitable for most bedding. Cleaning involves ventilation, steam cleaning for stains, and odor neutralization with vinegar and lemon. The mattress is heavy at 52 pounds, requiring care during setup. Its hybrid build combines foam comfort with spring support for a durable sleep surface.

Materials are certified for safety and performance. The foam is CertiPUR-US certified, ensuring low emissions and durability. It is also OEKO-TEX certified and free from fiberglass, complying with flammability standards. The pocket coils are designed for longevity and quiet operation. The cover is removable only for cleaning, not machine washable. Setup requires unrolling and waiting 24-48 hours for full expansion, though some reviewers used it sooner. The mattress fits standard full-size frames and works with adjustable bases, though it may initially resist bending. The design prioritizes ease of use with bed-in-a-box convenience. Maintenance involves regular rotation and spot cleaning. The build quality receives positive remarks from reviewers for value and comfort. However, its weight and firmness may require adjustments like mattress toppers for some sleepers. Overall, the design focuses on hybrid benefits: foam contouring and spring support in a certified, convenient package.
