About the Simba Sleep Hybrid Ultra Mattress
Last checked
The key specification is the medium-firm feel, rated 4 out of 5, rather than a soft, sink-in foam feel or an uncompromising orthopaedic one. Simba’s “Hybrid Ultra” naming places it in the foam-and-spring hybrid camp, so the practical expectation is a comfort surface with some contouring over a more responsive support system than an all-foam mattress. That matters. A medium-firm hybrid under an “Ultra” badge is a mainstream, relatively safe build choice: compared with open-coil mattresses it should feel more controlled under load, but the label itself points to balanced support rather than hotel-bed softness. The comfort story, therefore, has to be read through resistance as much as material. Medium-firm usually gives enough surface compliance for shoulders and hips while keeping the pelvis from dropping too far, which is why it tends to suit mixed side/back use better than very firm traditional sprung beds. The trade-off is obvious: hourglass side sleepers who need deep shoulder and hip immersion may find the support doing its job before the comfort layer has let them in far enough, while back sleepers are more likely to benefit from that flatter, braced feel.
That medium-firm setting is also where the owner feedback makes most sense. Buyers repeatedly describe easier sleep, less morning soreness and strong comfort for back-pain-prone bodies, which lines up with a hybrid mattress intended to combine pressure relief with a more buoyant support core. Couples get a specific positive signal too: partnered owners consistently mention not being disturbed much by movement, a benefit the hybrid format can plausibly deliver when the spring response is individually controlled rather than behaving like a single open-coil sheet. It is not universally firm. The clearest product-side warning is softness: some unhappy owners experience quick sinkage or a dipped feeling, so heavier back sleepers and side sleepers who dislike being held in the mattress may find the medium-firm label over-promises on resistance. The service complaints are separate from sleep feel but still relevant to ownership; low-rated feedback repeatedly flags fulfilment or customer-support frustration, including missing parts on associated bases and slow cancellation help. A recent owner also found the mattress deep enough to raise the bed height and make existing fitted sheets impractical, though that appears more of a sizing nuisance than a broad comfort fault. The strongest case is for average-weight side/back sleepers sharing a bed and wanting cushioning without obvious partner disturbance; very curvy side sleepers are better served by a softer hybrid, while heavier sleepers seeking firmer hold are better matched to firmer pocket-sprung or higher-support hybrid builds.

Specifications
Manufacturer specifications without the jargon, easy to scan and compare.
Comfort choice – Medium to Firm
Medium to Firm indicates a balanced feel that supports the body while maintaining some softness without sacrificing sturdiness. This level of firmness suits those who prefer a supportive yet slightly cushioned sleeping surface, which can alleviate pressure points.
6300 Triple layer Aerocoil® conical springs – provides optimum personalised, contoured pressure relief and support. These 3 layers of conical shaped springs aid air flow, for a cooler night’s sleep, and limit the transfer of movement to help minimise partner disturbance
Small cone-shaped coils flex in stacked layers under heavier areas, while the open spaces between them let heat move away and reduce the ripple from a partner turning. Sudden shifts may reach very sensitive sleepers.
PureLift™ Support boosting layer – this natural layer blend of latex and coconut fibres provides extra support and sumptuous comfort
Latex and coconut fibres add a firmer pad inside the mattress, steadying the sleeper across a broader area and reducing that hammock-like dip some softer builds can develop. Soft-bed seekers may find this too braced.
Free 10 Year Guarantee – for peace of mind
Fault cover gives you a route to repair or replacement if manufacturing defects appear after delivery, reducing the risk of paying again for the same issue. Every claim will need the seller's terms to back it.
Zip-off top cover – machine washable at 40°C, keeps it feeling fresh and cool, night after night
Cover panels detach from the sleep surface, letting sweat, skin oils and small spills wash out at 40°C before stale smells settle in. Frequent washing can wear fabric, while drying space is required.
Designed in the UK
Home-market planning usually shapes the sizing, fire labels and base compatibility, helping the mattress fit familiar rooms and frames. Manufacture, materials and aftercare may come from elsewhere.
CertiPUR® Stabilising Core foam layer – works in conjunction with the Simbatex® foam and Aerocoil® springs to provide extra pressure relief comfort and support
Middle foam spreads body weight across the spring layer, because steadier compression can mean fewer hard spots under heavier areas. People after a very firm surface may prefer less cushioning.
Delivered rolled in a box – for convenience, ease of access and manoeuvring to your room of choice
Carton packing turns the mattress into a smaller load for tight hallways and stair turns, because you steer the package before it expands. Repacking it is not realistic after it has expanded.
Simbatex® dual foam layers (50mm total) – provides double the amount of cushioning and air circulation from the graphite infused open structure foam to help release heat and humidity, for a fresher night's sleep
Graphite-infused foam yields under pressure while open cells let heat and moisture escape, and the surface should stay less clammy overnight. Deep sinkage can block some of that cooling path.
CertiPUR® High density foam base & cover – provides stability and support throughout the entire mattress
Dense lower foam steadies the upper layers beneath you, because a firmer platform lets the surface recover more evenly as you turn. Firmness-sensitive side sleepers may prefer a softer base.
FusionCool™ Layer – naturally sustainable wool and kapok fibres combined with charcoal-infused bamboo help to create a fresh, breathable, body temperature regulating microclimate
Fibrous comfort layers move moisture away from the sleep surface, because trapped dampness is what makes bedding turn clammy overnight. Let the mattress breathe after humid nights.
Stratos® cool-touch cover treatment – helps to remove excess heat for a cooler night's sleep
Cover fabric draws warmth away from the top layer, reducing that muggy contact under your back during warmer nights. Very cold bedrooms may make the surface seem chilly at first.
SupportCore™ Sprung Base containing 1000 pocket springs – adds additional breathability, provides firm support and optimises the sleep surface all the way to the edge of the mattress
Rows of small fabric-wrapped coils under the mattress let air move beneath you and steady the surface right out towards the sides. The edge may push back harder than the middle.
Mattress height – 34cm
Deep sides put the top panel higher above the base, easing access for some sleepers while asking for deeper fitted sheets. Low headboards can disappear behind the thicker edge.
Luxury soft-touch, breathable stretch knit cover – works in harmony with the springs and fillings to contour to each sleeper's body shape
Knitted top panel moves with the upper layers, letting the surface dip under pressure and spring back as you turn. It won't cool a warm room or thick bedding.
MTick accredited menopause-friendly mattress – endorsed by GenM, the independent menopause partner for brands, for helping to alleviate night sweats, one of the 48 signs of menopause.
Sweat-prone nights should feel cooler because the cover moves heat and moisture away from your body before it feels clammy. Hot flushes can wake you anyway.
