KISLOT Queen Size Mattress - 12 Inch Medium Firm Foam Hybrid with Pocket Springs, Motion Isolation, Edge Support, CertiPUR-US Certified, Mattress in a Box

Product Overview

This KISLOT mattress measures 62.6 inches long by 11.12 inches wide by 12 inches thick in the queen size, weighing 83.6 pounds. It features a three-layer construction with a fabric blend cover, comfort foam layer, and high-density foam base housing 500 individually wrapped pocket springs. The hybrid design combines foam's pressure relief with springs' bounce and edge support. The manufacturer describes a zoned support system that provides extra reinforcement for the lumbar and hip areas to promote spinal alignment. The knitted fabric cover is breathable and moisture-wicking to help regulate temperature. Setup involves unrolling the vacuum-sealed mattress, carefully cutting the plastic wrap, and allowing 48 hours for full expansion. Reviewers note the mattress feels softer than the 'medium firm' label suggests, with some describing it as marshmallow-soft while others find it supportive. The compressed shipping makes it manageable for one person to position, though its weight requires care during placement. The mattress fits standard queen bed frames and foundations.

Design & Build

The KISLOT Hybrid Mattress features a three-layer construction with a fabric blend cover, comfort foam layer, and high-density foam base containing 500 individually wrapped pocket springs. The cover uses a breathable knitted fabric that stretches to accommodate the layers beneath while promoting airflow. The comfort foam layer provides initial cushioning and pressure relief, working with the pocket springs to create a medium-firm feel. The pocket springs are arranged in zones, with denser coils in the lumbar and hip areas for extra support. Each spring moves independently to isolate motion and contour to body shapes. The mattress measures 12 inches thick, with the springs accounting for most of the height. The edges are reinforced with additional support to prevent roll-off and maximize usable surface area. The entire mattress compresses for shipping, arriving in a box that requires careful unrolling and plastic removal. Setup is straightforward but requires waiting 48 hours for full expansion and off-gassing.

Materials include CertiPUR-US certified foams, which meet standards for content, emissions, and durability. The pocket springs are made of steel and individually encased in fabric to prevent noise and friction. The cover is removable only for spot cleaning, as the manufacturer recommends against machine washing. The mattress weighs 83.6 pounds, making it manageable for one person to position with care. Aesthetics are minimal, with a simple gray fabric cover and no prominent branding. The mattress works on most foundations, including slatted frames, box springs, and adjustable bases. Maintenance involves regular rotation every 3-6 months to ensure even wear, though some reviewers note the mattress develops temporary body impressions that disappear within minutes. The hybrid design aims for durability, with the pocket springs resisting sagging better than all-foam options.

Performance

Reviewers report the mattress provides good motion isolation, with many noting they don't feel their partner's movements during the night. The pocket springs and foam layers work together to dampen vibrations and prevent disturbance. One reviewer mentioned the mattress eliminates the feeling of traditional springs poking through. The medium-firm feel is subjective, with several users describing it as softer than expected, comparing it to a marshmallow. Heavier sleepers over 400 pounds report adequate support, while lighter individuals may find it too plush. The zoned support system aims to align the spine, but some users experience morning back pain, suggesting the mattress may not suit all body types. Edge support receives positive comments, with users feeling secure when sitting or sleeping near the perimeter. The mattress bounces back quickly from compression, with temporary body impressions fading within minutes according to one reviewer.

Temperature regulation benefits from the breathable cover and airflow around the pocket springs. Users don't report overheating, though the foam layers may retain some heat compared to all-spring designs. The mattress maintains its shape well over initial use, with no significant sagging reported in the first weeks. Noise is minimal, with the individually wrapped springs preventing the squeaks associated with traditional innersprings. Durability appears promising based on early feedback, though long-term performance remains untested. The compressed shipping causes no permanent damage, with the mattress expanding fully within 48 hours. Some users note a slight off-gassing odor that dissipates within a day. The hybrid construction offers a balance between contouring and support, though those preferring very firm surfaces may find it too soft. The mattress accommodates various sleeping positions, with side sleepers appreciating the cushioning and back sleepers benefiting from the zoned support.
