About the Simba Sleep Earth Apex Mattress
Last checked
This is aimed at shoppers who want a premium-feeling hybrid without moving into an all-foam, slow-sinking mattress. Simba’s Earth Apex sits as a natural-material hybrid with a medium-firm, 4 out of 5 feel, so the comfort promise is support first, cushioning second. The firmness is the headline here. The honest read is a materials-led premium hybrid: wool and breathable fibres do more to define the surface feel than a headline spring-count story, placing it closer to the natural-hybrid tier than to standard memory-foam hybrids. That is a useful distinction, because wool tends to give a drier, more temperature-balanced contact layer than dense foam, while the hybrid core is there to hold the body level rather than let the hips drop deeply. The build also sounds physically substantial in real homes, with more than one account flagging extra depth and a higher sleeping position compared with an older mattress; that adds a sense of solidity, but it also means deeper sheets and harder handling can become part of ownership. On paper, the medium-firm tension is well judged for back sleeping and broad side-sleeping comfort, though it is not the plush, high-sink feel some curvier side sleepers look for.
The wool-and-hybrid combination gives the clearest fit to average-weight back sleepers, combination sleepers and couples who want a steadier, cooler surface than older memory foam. Happier accounts repeatedly describe the mattress as supportive without feeling hard, with less tossing, fewer stiffness complaints and noticeably better temperature control; one partner-disturbance theme also lines up with the hybrid brief, as several sleepers mention being less bothered by movement from the other side of the bed. Side sleepers can do well on this tension if their shoulders and hips do not need much extra give, but one detailed return linked discomfort to the raised surface pattern rather than the firmness alone, which is a useful warning where spinal sensitivity or a preference for a flat orthopaedic top is involved. Delivery is the real risk. Multiple low-scoring accounts focus not on the mattress feel but on failed or delayed delivery, poor communication, refund frustration and confusion around access, with one case specifically involving difficulty getting a king size upstairs; the heavy, deep build praised by satisfied buyers is also the same trait that makes awkward staircases less forgiving. For average-weight back sleepers and side sleepers wanting a breathable natural hybrid with good partner stability, this is the right call. For pronounced-curve side sleepers needing deeper pressure relief, or homes with difficult delivery access, look at softer natural hybrids or flatter-topped pocket-sprung mattresses instead.

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.
CoreMAX™ Sprung Base containing 1000 pocket springs – seven support zones of springs provide additional support where it's needed the most, and optimises the sleep surface all the way to the edge of the mattress
Pocketed coils under the mattress move on their own, sharing your weight across the base, and the outer edge is less prone to sag when you lie close to it. Repeated edge pressure will wear that firmer border faster.
Viscose damask cover – with invisible tufting for a soft, smooth, breathable and durable sleeping surface
Stitching hidden below the top fabric keeps the sheet-facing panel flatter, while the woven cloth lets warm moisture escape before the bed turns clammy. A protector is sensible, since body oils can mark the fabric.
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.
5700 Triple layer Aerocoil® conical springs – for optimum personalised, contoured pressure relief and support. These 3 layers of conical shaped springs aid air flow, for a cooler nights sleep, and limit the transfer of movement to help minimise partner disturbance
Spring stack moves in small sections beneath you, easing pressure points while ventilation through the layers can make warm nights less stuffy. Very light sleepers may notice some movement across the bed.
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.
Opulent Cashgora Wool & Silk cushioning layer – due to their natural qualities helps to offer a fresher night's sleep and provides sumptuous comfort
Cashgora wool and silk fibres sit near the surface, adding a soft, breathable pad that can take the edge off humid nights. Compression over time is possible, while airing takes a little effort.
Hampshire British wool layers – fully traceable and naturally sustainable breathable wool fibres help to regulate body temperature, reduce humidity and provide durable support
Wool fibres absorb moisture vapour and let excess heat escape, reducing that clammy build-up during warm nights or under thick duvets. Compressed wool may settle in the areas used most.
British Wool layers – luxuriously soft comfort and support, naturally breathable and durable too. Helps you sleep warmer in Winter and cooler in Summer
Wool fibres trap air, move moisture and keep the surface less clammy in warm weather, then less chilly once the room drops. Wool can compress over time, and airing lets it recover.
British Wool stability layers – two additional layers of wool are included to help provide increased breathability throughout the mattress and give added support
Wool pads can wick moisture and steady the surface. They may add a firmer top than plain foam, though anyone avoiding animal fibres or seeking deep sink should look elsewhere.
Mattress height – 32cm
Taller sides raise the sleep surface on the bed base and can help you get in and out with less bend. Deep fitted sheets may sit tight at the corners.
