Simba Go Hybrid vs Una Organic Delux vs Una Organic Essential

The Simba Go Hybrid is a medium-firm mattress, however, 95% of Simba sleepers love their mattress. If it doesn't work for you, Simba mattresses that are returned are either refurbished or recycled; they never go near a landfill site.

The Una Delux is the ultimate in customisation, with individualised adjustable comfort. Yes, 6 firmnesses are available on each side of the mattress! Simply unzip the cover, and swap the soft, medium and firm latex comfort layers into a different order according to your personal preference. This makes the mattress ideal for couples with different mattress firmness preferences, and those looking for flexibility to make the mattress softer or firmer in the future.

The Una Essential has individualised adjustable comfort. Two firmnesses are available on each side of the mattress! Simply unzip the cover, and swap the medium and medium-soft latex comfort layers to adjust the firmness. You decide your comfiest firmness by having either the medium or medium-soft layer on top.

The Simba Green Organic Go Hybrid is Simba's most sustainable and organic mattress, with half the carbon footprint of traditional Hybrids. The six layers of the Go Hybrid® are:

• Breathable GOTS-Certified Organic Cotton Cover
• Breathable, Recycled Simba Renew layer (up to 75% recycled)
• GOLS-Certified Natural Latex
• Up to 2,000 25mm conical pocket Aerocoil™ springs, enclosed in a 100% polypropylene pocket
• 5 Zone Supportcore™ base with up to 900 pocketed steel barrel springs
• Breathable 3D mesh base cover made with 50% recycled fibres.

The Una Mattress™ Organic Mattress Delux is 7cm thicker than the more affordable Essential. The four layers of the Delux are:

• Super Soft Organic Wool & Cotton Cover
• Organic Latex
• Medium Organic Latex (Density 85 kg/m3)
• Soft Organic Latex (Density 75 kg/m3)
• Firm Organic Latex (Density 95 kg/m3).

The Una Mattress™ Organic Mattress Essential is more affordable than the Delux but with a similar construction. The three layers of the Una Essential are:

• Super Soft Organic Wool & Cotton Cover
• Organic Latex
• Medium Organic Latex (Density 85 kg/m3)
• Medium-Soft Organic Latex (Density 75 kg/m3).

Latex is a renewable, bountiful, and biodegradable material, as well as being naturally anti-microbial. With no chemical glue between mattress layers it makes disassemling and recycling even easier.

What makes the pocket spring base so unique, is its sustainability factor: it is 100% recyclable because there is nothing in it apart from steel and recycled fibres. Plus it can be rolled and boxed, which makes this mattress it more efficient to transport thus reducing its carbon footprint.

100% organic certified materials mean you can relax without a care. The comfy latex is harvested and refined from the milk-like sap of a rubber tree called Hevea Brasiliensis, without adding smelly petrochemicals. The processing of latex mattresses actually encourages tree growth and is extremely sustainable. This process encourages the healthy growth of rubber trees as they can be tapped for up to 30 years. The natural soft organic wool and cotton cover replaces the need for fire-retardant chemicals, so you can breathe easy right from the first night.

Organic Latex
This Global Organic Latex Standard (GOLS) certified latex has added perforations to encourage airflow, and graphite to absorb excess heat.

Aerocoil® springs
These patented micro springs help prevent overheating with increased air circulation and ultra-responsive comfort - flexing gently in response to you and your partner's every movement, offering personalised support to one without disturbing the other.

Supportcore™ springs
A spring base, rather than foam, encourages even more airflow through the mattress.

Is a combination of recycled and new fibres that allows maximum airflow through the mattress layers and aids shape retention. It is made with 50% recycled fibres.

Organic Comfort Layers
Natural latex foam has an open-cell structure to permit constant airflow allowing you to sleep cool. Latex is also naturally antimicrobial, meaning it repels nasty organisms, making latex an excellent choice for people with allergies.
