Features CertiPUR® certified foams, ensuring no harmful chemicals.
Assessed from Simba's published specification for this mattress, captured September 2026, and from regular price comparison across our UK retail partners.
The main reason to choose the Luxe is depth of support. Two layers of Aerocoil microsprings sit above a further microspring layer and a sprung base, which means the mattress responds to pressure at several levels rather than one. The thirteen support zones target areas like your back, hips and shoulders. Temperature control is the other strength: a zip-off cooling cover, British wool infused with bamboo, and Simbatex foam all work on airflow and moisture. You also get a 200-night trial with free returns during that period, and free delivery to most of the UK, seven days a week when you pick a date at checkout. Yes, it's expensive, but the risk sits with Simba rather than you.
Key Features & what's inside
- Soft, cooling cover. A zip-off, washable cover with Stratos tech that prevents heat build-up, which means you can keep it fresh without wrestling the whole mattress. Hot sleepers should notice the difference on warm nights.
- Bamboo infused wool layer. British wool infused with moisture-wicking bamboo for better breathability. Wool naturally regulates temperature, so this layer helps in winter as well as summer.
- Fresh Simbatex foam layer. Simba's own foam with enhanced airflow and superior elasticity, which means cushioning that springs back quickly rather than leaving you feeling stuck.
- Two layers of Aerocoil springs. A double layer of patented microsprings arranged in thirteen supportive zones. These target parts of the body with specific needs, like your back, hips and shoulders.
- Stabilising core foam layer. A CertiPUR foam layer that provides structural support and extra airflow. It keeps the layers above it working consistently.
- Micro spring support layer. An extra layer of up to 900 high carbon steel microsprings for maximum support. This is where the mattress earns its medium-firm side.
- SupportCore sprung base. Up to 1,000 pocketed, tempered steel barrel springs giving firm, edge-to-edge support with no roll-off. That means you can use the full width of the bed, right to the edge.
- High-density foam base and cover. CertiPUR foam with a breathable cover made from recycled yarn. It gives the whole mattress its stability.

Who's it NOT for?
If you prefer a properly soft, sink-in feel, the medium-firm/plush profile may be slightly more supportive than you'd like. Budget shoppers should look elsewhere too: from £1,249, this is a premium purchase. And at 31cm deep, it's a heavy mattress to move and needs deep fitted sheets.

Is the Simba Hybrid Luxe firm or soft?
Simba describes it as medium-firm/plush, meaning a cushioned, softer surface over a supportive core. It suits most sleepers, although lightweight side sleepers may find it a little too firm, and anyone wanting a very firm bed may find the plush top layers too giving.
How many springs does the Simba Hybrid Luxe have?
It contains 5,700 springs in total, spread across several layers: two layers of Aerocoil microsprings, an extra microspring layer of up to 900 high carbon steel springs, and a base of up to 1,000 pocketed barrel springs. That layered approach means support at multiple depths rather than one.
Does the Simba Hybrid Luxe come with a trial?
Yes. Simba offers a 200-night trial with free returns during the trial period, plus a 10-year guarantee. Delivery is free to most of the UK, and you can choose delivery seven days a week when you pick a date at checkout.
Is the Simba Hybrid Luxe good for hot sleepers?
It's designed with hot sleepers in mind. The zip-off cover uses Stratos tech to prevent heat build-up, a wool and bamboo layer wicks moisture, and Simbatex foam adds airflow. Owner reviews on Simba's site frequently mention good temperature regulation. An optional HeatRelease upgrade with graphite is also available.
How much does the Simba Hybrid Luxe cost?
Prices range from £1,249 to £1,999 depending on size, with six sizes available from UK Single through to Super King, plus an EU King. It's a premium price, but the 31cm depth, 5,700 springs and long trial go some way to justifying it.
