Simba Hybrid Luxe Mattress

The Simba Hybrid Luxe is a premium 31cm deep hybrid mattress sitting at the top of Simba's core Hybrid range. It is built around two layers of up to 3,800 Aerocoil titanium alloy microsprings, a SupportCore base of up to 1,000 durable steel springs, and topped with a natural bamboo-infused British wool layer, graphite-infused Simbatex foam and CertiPUR certified foam layers. The result is a deeply supportive, temperature-regulating mattress with exceptional motion isolation and edge-to-edge support - designed for sleepers who want the full Simba experience without compromise.

Who Is This Mattress For?

A premium hybrid mattress best suited to sleepers who want medium firm support, exceptional temperature regulation and outstanding partner disturbance reduction across a multi-spring, multi-layer build.

Medium Firm Feel - 4/6: A supportive feel with added stability. Ideal for people who change sleeping position during the night and need a balance of comfort and support.

Best for

• Back sleepers - multiple spring layers and the wool comfort layer keep your spine properly aligned while providing a cushioned surface to lie on
• Front sleepers - the firm SupportCore base and dual Aerocoil spring layers prevent hips from sinking too far while remaining comfortable throughout the night
• Combination sleepers - the responsive spring system adapts quickly as you move, so the mattress works however you sleep
• Side sleepers - the bamboo-infused wool and Simbatex foam layers cushion shoulders and hips to relieve pressure points
• Couples - two independent Aerocoil spring layers and the SupportCore base combine to minimise motion transfer so you won't disturb each other
• Hot sleepers - bamboo-infused wool wicks moisture, graphite-infused Simbatex draws heat away from the body, and the Aerocoil springs push fresh air through the mattress as they compress
• Allergy sufferers - Simbatex is hypoallergenic and dust mites cannot survive on the material
• Those wanting Simba's most advanced spring-and-foam combination at a luxury price point
• Sleepers up to 114kg (18st) per side

Not ideal for

• Sleepers who prefer a very soft, sink-in feel
• Those who prefer a fully natural or foam-free mattress

Inside This Mattress

Aerocoil Titanium Alloy Microsprings (Two Layers - Up to 3,800 Springs)
What it is: Simba's patented conical microsprings made from titanium alloy and manufactured in Leeds. Two layers of these 25mm springs sit at the top of the mattress where comfort is needed most, each enclosed in an individual polypropylene pocket.
How it helps you sleep: Each spring compresses independently to follow your body's contours and reduce pressure on joints. As they compress, they push fresh air upwards through the mattress, actively cooling the sleep surface. Because they move separately, your partner's movements stay on their side.

SupportCore Steel Spring Base (Up to 1,000 Springs)
What it is: A durable steel spring base layer that forms the structural foundation of the mattress, engineered to provide robust edge-to-edge support.
How it helps you sleep: This base layer delivers the firm, consistent support your spine needs regardless of where you sleep on the mattress. Edge-to-edge support means the full sleep surface is usable, which is particularly beneficial for couples and those who sleep near the edge.

Bamboo Infused British Wool Layer
What it is: A natural comfort layer combining 90% British wool and 10% bamboo, sitting directly beneath the cover as the first layer of cushioning.
How it helps you sleep: Wool is a natural insulator and temperature regulator, keeping you cool in summer and warm in winter, while its hygroscopic properties encourage moisture to evaporate. Bamboo increases breathability and adds softness, helping you stay cool and dry throughout the night.

Graphite Infused Simbatex
What it is: Simba's advanced foam with graphite temperature-regulating properties providing superior pressure relief and spinal alignment.
How it helps you sleep: Keeps you cooler by drawing heat away from the body, while the hypoallergenic properties promote a healthier sleep space and the eco-friendly production process is kinder to the planet.

CertiPUR Foam Layer
What it is: Simba's high-quality certified foam layer, free from harmful chemicals, with an open-cell structure for improved airflow.
How it helps you sleep: Provides excellent support and pressure relief with enhanced breathability for a cooler sleeping environment, while the certification guarantees a healthier sleep product.

Edge to Edge Support
What it is: A mattress design where support is maintained consistently from one edge to the other, delivered here by the SupportCore steel spring base.
How it helps you sleep: Gives you a larger effective sleeping area by providing firm, reliable support even at the very edges, preventing the roll-off feeling.

Removable Knitted Cover
What it is: A 500g soft-to-touch knit fabric cover with a zip-off top surface that is machine washable at 40 degrees Celsius on a reduced spin cycle. An internal cover beneath also protects the mattress layers when the top cover is removed for washing.
How it helps you sleep: Keeps the sleep surface fresh and hygienic with minimal effort - simply remove and wash when needed for a consistently clean environment.

Easy Care
What it is: A no-turn mattress design that requires only periodic rotation from head to toe rather than flipping.
How it helps you sleep: Simple maintenance means your mattress stays in optimal condition with minimal effort, ensuring consistent comfort and support night after night.

Dimensions and Weights

How it Compares

Vs firmer models: The Simba Hybrid Luxe's dual Aerocoil spring layers and bamboo-infused wool comfort layer provide significantly more pressure relief than a firm or extra firm mattress. If you sleep on your side, share a bed or tend to run warm at night, this is likely the stronger choice. Firmer models suit heavier sleepers or those who want the most rigid, minimal-sink surface possible.

Vs softer models: The Simba Hybrid Luxe has considerably more underlying structure than a soft or soft medium mattress, with three independent spring layers and a stable CertiPUR foam base. Softer options feel more immediately plush but may not maintain spinal alignment as consistently for back and front sleepers, and can compress over time. The Luxe's build is engineered to hold its shape and support level night after night.

Vs the Simba Hybrid and Hybrid Pro: The Hybrid Luxe adds a third layer of Aerocoil springs and a natural bamboo-infused British wool comfort layer that the Hybrid and Hybrid Pro do not have. It is 6cm deeper than the Hybrid and 3cm deeper than the Pro. Where the Hybrid and Pro suit most sleepers well, the Luxe is aimed at those who want a noticeably more cushioned and temperature-regulated sleep surface, with more robust edge support and the reduced motion transfer that comes from having three spring layers working together.

10 Year Guarantee

The Simba Hybrid Luxe is backed by Simba's 10-year manufacturer's guarantee against defects in materials and workmanship. For a mattress built around titanium alloy springs manufactured in Leeds, a durable SupportCore base and NBF-approved construction, this is a reflection of what Simba expects this mattress to deliver over its working life. If it fails within that period, Simba will exchange it for a brand new one.
