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 SupportCore™ 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.

Nectar

Is Nectar good for heavy side sleepers?

Indeed, the Nectar mattress is generally well-suited for heavy side sleepers. Its top layer, composed of gel memory foam, is designed to relieve pressure, particularly around the shoulders and hips. This feature caters to the needs of average to heavy side sleepers by offering enhanced support and comfort.

Is Nectar mattress good for back pain?

Yes, the Nectar mattress can be beneficial for individuals with back pain, particularly those of average weight. Its design provides effective pressure relief that can alleviate discomfort in areas such as the hips, shoulders, or back. However, heavier individuals who sleep on their back or stomach might sink too much into the mattress, potentially affecting ergonomic alignment. So, individual comfort and weight should be considered when choosing this mattress for back pain relief.

What is the life expectancy of a nectar mattress?

The lifespan of a Nectar mattress, which is a 25cm thick all-foam memory foam bed, is typically around nine years, given proper care and maintenance. This includes rotating the mattress every three to six months and ensuring the bedding is kept clean. Therefore, with appropriate usage and care, you can expect a Nectar mattress to provide comfort and support for close to a decade.
