FAQs
Simba Green Organic
Is the Simba GO mattress any good?
The Simba Go mattress offers a sustainable design, combining patented technology with natural, biodegradable latex for excellent pressure relief and cushioning. Constructed with six layers, each element contributes to enhancing your sleep experience. It stands out as Simba's most eco-friendly mattress, with half the carbon footprint of traditional hybrids. This blend of natural, organic materials with advanced technology makes it an attractive choice for those prioritizing both comfort and environmental impact.
Are Simba Go mattress bouncy?
The Simba Go mattress does possess some level of bounce due to its supportive Aerocoil spring layer, consisting of up to 2000 patented cone-like springs that enhance body support and improve airflow. It also features a zoned SupportCoreโข base with up to 900 pocketed springs for targeted support, especially in areas like the hips and shoulders. However, its firmness is enhanced by a GOLS Organic Latex comfort layer, a perforated natural latex layer that not only increases breathability but also provides luxurious support and excellent pressure distribution.
Is the Simba Go mattress hot?
The Simba Go mattress is designed with several features that promote breathability, which should help keep you cool while you sleep. The GOTS organic cotton cover and a 3D mesh layer both support maximum airflow through the mattress layers. It also features an Aerocoil spring layer with up to 2000 springs, promoting increased airflow, along with a SupportCore base with pocketed springs for targeted support. While the latex layer might retain some heat, this should be offset by the breathability of the other layers, and overall, heat retention shouldn't be a major issue.
