The Luna 6000 Plush is 27cm deep, and its starting price is fair for this level of construction. The top layer uses open cell memory foam, which means it should sleep cooler than traditional memory foam while still moulding around you. It comes in UK Double, King and Super King, so single sleepers will need to look elsewhere. It's listed with a 10-year guarantee.

Why should you choose this mattress?
This mattress suits sleepers who want the contouring of memory foam without the deep sink or the heat. The medium firmness works for most sleeping positions, although those who prefer a firm, supportive surface may find the plush reflex foam layers a little soft for their liking. The dual spring system is the real appeal: individually pocketed springs adapt to your shape and reduce motion transfer, which means you're less likely to feel a partner moving, while the mini springs above add bounce and airflow. If you're buying from Mattress Online, there's a 100-night trial, though you'll need to buy a mattress protector from them to qualify.
Key features & layer details
Luna Fusion Cool Memory Foam
A 2cm layer with an open cell structure, which means better airflow and a cooler feel than standard memory foam. It adapts around your body for a cosy, cradled comfort.
Reflex Foam
A 3cm layer of reflex foam that adds cushioning. This is part of what gives the mattress its plush feel.
Reflex Foam
A second, deeper 5cm reflex foam layer continuing that soft cushioning. Together the two layers create the plush surface the name promises.
Mini Pocket Springs
A layer of 2,000 mini springs sitting between the foam and the main spring core. These add breathability and a gently bouncy feel.
Luna Pocket Springs
The core of 4,000 Luna Pocket springs, each encased in its own fabric pocket. Every spring moves independently, which means support tailored to your shape and less disturbance from a restless partner.

Best suited for?
Couples
Individually pocketed springs move independently and reduce motion transfer, which means you are less likely to feel a partner turning over during the night.
Warm sleepers
The open cell memory foam on top allows better airflow than standard memory foam, so it should feel cooler while still moulding around you.
Side sleepers
Medium firmness with a plush top of memory foam and two reflex foam layers gives cushioned, contouring comfort around the shoulders and hips.
Combination sleepers
The medium feel suits most sleeping positions, and the bouncy mini springs above the core make it easy to shift around without feeling stuck.
There's no single size, so it won't work for a child's room or a small guest bed. If you prefer a firm, board-like surface, this might not be the best choice, as the plush foam layers give a noticeably soft top. And if you like the deep hug of all-foam mattresses, the springy feel here may disappoint.
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 Luna 6000 Plush mattress?
It's rated medium, with a plush top thanks to the layered reflex and memory foams. That suits most sleepers, particularly side and combination sleepers, although anyone who prefers a properly firm surface may find it a little too soft.
Does the Luna 6000 mattress sleep hot?
It's designed not to. The top layer is Luna Fusion Cool memory foam with an open cell structure to increase airflow, and the mini pocket spring layer adds breathability. If you're a very hot sleeper, a hybrid like this is generally a safer bet than an all-foam mattress.
Does the Luna 6000 mattress come with a trial?
Mattress Online lists a 100-night trial, but this is the retailer's own offer rather than a Luna guarantee, and it requires you to buy a mattress protector from Mattress Online to be eligible. Check the terms before you order.
How many springs does the Luna 6000 have?
6,000 in total: a core of 4,000 Luna Pocket springs, each moving independently in its own fabric pocket, plus a layer of 2,000 mini pocket springs above for bounce and airflow.
What sizes does the Luna 6000 come in?
UK Double, King and Super King. There's no single size, which is a shame for smaller rooms.
