How to Choose the Best King Size Mattress
Choose between 7-zone and 9-zone support systems
The dosleeps range uses a 9-zone layout made of bucket-shaped tempered stainless steel coils in fabric pockets to isolate pressure points across nine distinct areas. In comparison, models like the Queblox, Matoresu Hybrid, and TeQsli use 7-zone structures that focus firmer support specifically under the hips and shoulders. If you need targeted zoning for heavy support areas, 7-zone options provide focused alignment, whereas 9-zone builds distribute pressure over more incremental points.
Decide between pure foam and pocket spring hybrids
The Uliyati is an all-foam mattress featuring a 20cm depth split across four distinct foam layers, including gel memory foam and bamboo charcoal foam without metal springs. Hybrids like the Vesgantti, Vantto, and Twirest combine comfort foam layers with individual pocket springs to offer a medium-firm spring response. The all-foam Uliyati offers soft contouring without spring bounce, whereas hybrid designs provide stronger border stability and individual spring motion isolation.
Match cover materials and temperature management to your sleep habits
Cooling and cover fabrics vary across these models. The dosleeps mattresses feature a Tencel Lyocell fabric cover to manage moisture, while the Matoresu Hybrid and TeQsli incorporate multi-molecular cooling gel memory foam beneath skin-friendly covers. If you want simple surface maintenance, the Uliyati features a grey dirt-resistant cover that can be wiped clean with a damp cloth, whereas the Vesgantti offers a choice of knitted fabric in white or grey to match bedroom decor.
Check for specific safety certifications and edge support needs
If material testing is a priority, the Vantto 10-inch mattress uses CertiPUR-US certified memory foam that contains no fiberglass, while the Matoresu Hybrid holds OEKO-TEX certification. For those who sit on the edge of the bed or want to use the full 150x200cm sleeping area, the Queblox, TeQsli, and Vesgantti models feature reinforced edge support systems to prevent sagging and roll-off.

The Vantto 10-inch hybrid mattress uses memory foam certified by CertiPUR-US to be free of fiberglass and harmful substances. The Matoresu Hybrid mattress carries OEKO-TEX certification for its fabric and foam components.
How do 7-zone and 9-zone support structures work on a king size mattress?

The Queblox, TeQsli, and Matoresu Hybrid feature 7-zone systems engineered to provide firmer support under heavier areas like the shoulders and hips.
