Why should you choose this mattress?
The main draw is the medium-firm feel, which gives a supportive surface without being rock hard. That tends to suit back sleepers, and many people who share a bed and want steady support. Pocket springs are built from individually moving springs, which generally means less disturbance when your partner moves. The size range is wide, from Single up to Super King, so it should fit most bedrooms. It's priced in the mid-range. Lighter side sleepers may find the surface a little firm around the shoulders and hips.
Key features & layer details
Uno-Q memory cover
Memory foam quilted into the cover, designed to add comfort, breathability and a cool surface. You get a softer feel on top without sleeping on a thick layer of foam.
Premium Comfort Foam
A 3cm layer of foam that gives a sink-in sensation. It adds some cushioning over the firmer support below, which can help take the edge off the medium-firm feel.
Pocket springs
3000 pocket springs, 1000 Mid-Flex springs and 2000 U-Flow mini springs, move independently, and the U-Flow springs are there for airflow and temperature regulation. An eco-performance border encases them.
HD Endurance Foam
A base foam designed to provide stability and support from the bottom up. It gives the layers above a steady footing, so the mattress keeps its supportive feel.

Best suited for?
Back sleepers
The medium-firm feel gives a supportive surface without being rock hard, which suits anyone who likes to lie on their back with steady support.
Couples
Individually moving pocket springs mean less disturbance when your partner moves, and the Double, King and Super King sizes give two people room.
Combination sleepers
A medium-firm surface gives more support than cushioning, which should make it easier to shift between positions through the night without feeling sunk in.
If you prefer sleeping on a soft mattress, this might not be the best choice. Medium-firm gives more support than cushioning, so lighter side sleepers may feel pressure at the shoulders and hips. Uno doesn't publish a depth, so check it with the retailer if your bed frame needs a particular height.
Save on an earlier or ex-display model
