About the Horizon Odyssey 800 Pocket Memory Mattress
Last checked
An 800-pocket spring unit under a 2cm graphite-infused memory-foam layer makes the Horizon Odyssey a budget hybrid rather than a deep, luxury memory-foam mattress. At 23cm deep, with a knitted cover, foam-reinforced edges and a single-sided build, it sits in the practical rolled-mattress camp: easier to manoeuvre on delivery, simpler to rotate using the handles, but dependent on rotation rather than flipping to even out wear. An 800-count pocket unit is honest for this price tier, not generous; compared with 1000-2000 pocket hybrids higher up the market, the support is less finely segmented, so the springs should still respond independently but will not feel as closely contoured under different body zones. The foam layer is deliberately modest. Two centimetres of memory foam can soften the shoulder and hip contact points and give a little slow-response cushioning, yet it will not have the enveloping sink of thicker memory-foam hybrids, and the graphite-and-airflow language is better read as a cooling nudge than a guarantee against overheating. Edge support is the more concrete structural upgrade, especially on smaller sizes, while the BS7177 home-use fire compliance, hypoallergenic spec and 5-year guarantee keep the essentials tidy rather than exceptional.
The medium feel, pocket springs and shallow memory layer make most sense for average-weight back sleepers and side sleepers who want support without a pronounced foam cradle. Comfortable and supportive is the dominant owner signal, with several accounts linking the even pressure to better sleep, less back discomfort and enough memory-foam give for couples to settle without obvious roll-together; one recent account also singled out the reinforced edge for reducing the roll-off feeling, which matches the foam perimeter in the spec. The mattress can feel firmer than the marketing implies. A low-scoring buyer expected a softer surface and found it too firm, while another reported collapse within a fortnight, so softness-sensitive side sleepers and anyone worried about early body impressions need to treat the 2cm comfort layer and single-sided construction with caution rather than assuming plush pressure relief. At 26.8kg in a double and 28.6kg in a king, it is manageable for two people but still not effortless when rotating every three months. Temperature is the qualified bit: knitted fabric and graphite foam are sensible choices for a cooler memory-foam feel, but hot sleepers usually get more reliable airflow from latex hybrids or pocket-sprung mattresses with natural fibre fillings. If you're an average-weight sleeper wanting a medium hybrid with edge support and light memory-foam cushioning, this works. If you're seeking a soft, deep-sink surface or stronger long-term resilience, a £700-plus pocket-sprung hybrid with deeper comfort layers makes more sense.

Specifications
Manufacturer specifications without the jargon, easy to scan and compare.
No roll-together
Crafted with innovative technology, this item ensures independent sleeping zones, eradicating disruptions caused by movement by one person, thereby offering you a serene night's sleep. Furthermore, this distinctive attribute aims to promote even weight distribution, essentially contributing to better sleep posture and relieving areas of high pressure, ensuring you wake up refreshed and invigorated each morning.
Pocket Springs
Furnished with a generous count of pocket springs, this mattress offers superior reinforcement for your body while sleeping, ensuring each segment receives individualised support. This design brilliantly alleviates pressure points and enhances comfort, without negating the overall mattress durability, guaranteeing you a restful night for years to come.
Knitted cover
A knitted cover spells out a blend of cosiness with breathability, providing a comforting touch that many crave while ensuring your temperature remains well regulated throughout the night. This feature pairs comfort and functionality in a coveted balance, contributing to an intimate sleep environment that is warm, inviting, yet refreshingly aerated.
Medium
With a medium firmness level, this specification caters exquisitely to a substantial range of sleepers, being not too hard nor too soft. The presence of 1000 pocket springs, complemented by gel layers, intends to distribute weight evenly across the surface, aiding in maintaining correct spinal alignment and contributing to a restful night's sleep.
Rolled-up
Embracing a rolled-up design, this marvellous piece of sleep engineering ensures direct delivery from manufacturer to home, eliminating the need for any intermediary handling. This design also helps to consolidate both space and cost, but be aware it may require up to 48 hours to fully expand and reach optimal comfort levels.
Fire Resistant
Ensuring safety during your peaceful slumber, fire resistance is a crucial feature that reduces the risk posed by potential accidents involving flammable materials. Furthermore, it demonstrates the manufacturer's commitment to adhere to strict safety standards, prioritizing your well-being over all else.
Depth: 23cm
With a depth of 23cm, this mattress provides ample cushioning for a comfortable night's rest. The generous thickness may also ensure the durability and longevity of the mattress, offering users an investment in both comfort and lifespan.
Includes turning handles
Turning handles aid in the regular rotation of the mattress, thereby significantly extending its lifespan. Easy maintenance is always appreciated, and these handles streamlining the process by making rotation hassle-free and manageable.
5 year guarantee
Fault cover puts manufacturing problems in writing, making a loose strut, failed fixing or collapsed padding less of a gamble after delivery. Accidental damage, fabric marks and poor fitting usually sit outside it.
Hypoallergenic
Hypoallergenic mattresses are the perfect choice for those with allergies or sensitivities, as they protect against allergens and irritants. They're also a great choice for those with asthma or respiratory issues.
Pressure relief
Softer comfort layers let shoulders and hips sink slightly into the surface, spreading body weight before you feel sharper points building. Front sleepers may want firmer support to keep the hips level.
Reinforced mattress edge
Firmer sides help the mattress hold its shape when you sit or sleep near the border, giving you more usable width across the bed. It won't stop a soft comfort layer dipping under weight.
Memory Foam
Foam in the comfort layer softens under body heat, letting shoulders and hips sink closer into the surface while reducing sharp pressure points. It can feel warmer and slower to move on.
Single-sided
Bed-making is simpler because the comfort layers stay on the top face, leaving the underside to stabilise the mattress while you lie on the cushioned surface. Don't flip it over.
23cm deep
Mattress sides add enough bulk to lift the sleep surface, making fitted sheets sit fuller and the bed feel less low. Very deep sheets may bunch at the corners.
