Horizon describes the Adventurer 1000 as medium to firm, so it suits back and combination sleepers who want a supportive feel with a little give on top. It's 25cm deep and sits at the affordable end of the hybrid market, and the price reflects what you get: sensible construction rather than luxury extras. It comes with a 100-night trial and a 5 year guarantee, which takes some of the risk out of buying online.

Why should you choose this mattress?
This mattress makes sense if you want hybrid comfort on a modest budget. The bamboo infusion in the memory foam helps dispel heat and moisture, which means you're less likely to get the clammy feeling traditional memory foam can cause. The 1000 pocket springs move independently, so a restless partner is less likely to disturb you. It's hypoallergenic, comes in five UK sizes from Single to Super King, and delivery is flexible: free to most locations, with next day weekday delivery or a chosen weekday up to 60 days ahead, all with a two-hour slot. Room of choice delivery and old mattress recycling are available for an extra charge.
Key features & layer details
Bamboo Memory Foam
A bamboo-infused memory foam layer moulds around your shape, which means built-up pressure on hips and shoulders is eased and aches are relieved. The bamboo adds breathability, helping to dispel heat and moisture.
High Density Foam
A durable, cushioning layer of high density foam sits beneath the memory foam, adding comfort. It also helps reduce motion transfer, so you feel less of a partner's movement.
Pocket Springs
1000 pocket springs respond individually to each area of your body, which means personalised support rather than a one-feel-fits-all base. They also cut down motion transfer between partners.

Best suited for?
Back sleepers
The medium firm feel gives a supportive base, while the bamboo memory foam on top adds a little give where your body needs it.
Combination sleepers
Individually responding pocket springs under a memory foam layer give a supportive feel with some cushioning, which suits anyone who changes position through the night.
Couples
With 1000 pocket springs moving independently and a high density foam layer, a restless partner is less likely to disturb you.
Warm sleepers
Bamboo-infused memory foam helps dispel heat and moisture, which means you're less likely to feel the clamminess traditional memory foam can cause.
Budget buyers
It sits at the affordable end of the hybrid market, offering sensible three-layer construction and a 100-night trial rather than luxury extras.
If you're a lightweight side sleeper, the medium to firm feel may press a little too hard on your shoulder despite the softer top layer. And if you're after a deep, hotel-style pillow top, the 25cm profile and budget-friendly build won't deliver that plush sink-in feel.
Save on an earlier or ex-display model
Some retailers still sell the earlier version of this mattress, or ex-display and returned stock at a lower price. These are the sizes where it costs less than the current model's best price.

FAQ's
How firm is the Horizon Adventurer 1000 mattress?
Horizon rates it as medium to firm. Owner reviews describe it as firmer than a true medium, with a softer top layer from the bamboo memory foam. That suits back sleepers and most combination sleepers, although lightweight side sleepers may find it slightly too firm.
Does the Horizon Adventurer 1000 sleep hot?
It should run cooler than traditional all-foam mattresses. The memory foam is infused with bamboo for breathability, helping to dispel heat and moisture, and the pocket spring core allows air to move through the mattress. If you sleep very hot, it's a sensible pick at an affordable starting price.
Is there a trial period for the Horizon Adventurer 1000?
Yes, it comes with a 100-night trial, so you can sleep on it at home before committing. There's also a 5 year guarantee covering manufacturing faults, which is reassuring at an affordable starting price.
How much does the Horizon Adventurer 1000 cost?
It depends on the size you choose, and the price table on this page shows the current price for each size. Five UK sizes are available: Single, Small Double, Double, King and Super King. For a 25cm hybrid with 1000 pocket springs and bamboo memory foam, that's good value rather than a compromise.
How is the Horizon Adventurer 1000 delivered?
It arrives vacuum-packed, which owners say makes handling easier. Delivery is free to most locations with a two-hour time slot, and you can choose next day on weekdays, a weekday up to 60 days ahead, or a weekend. Room of choice delivery and mattress recycling cost extra.
