Dunlopillo Elite Supreme 2340 Pocket Mattress
The Dunlopillo Elite Supreme 2340 Pocket is a hybrid mattress that pairs a Talalay latex comfort layer with a double layer of 2,340 calico pocket springs, which means you get springy, responsive pressure relief rather than the slow sink of memory foam.
- Phase-change top for hot sleepers

The Dunlopillo Elite Supreme 2340 sits at the medium to firm end of the scale and measures a substantial 33cm deep. Listed in UK King, it is a serious spend, but the natural materials, handcrafted UK construction and calico-pocketed springs go some way to justifying it. It is single-sided, so you rotate it rather than flip it.

Why should you choose this mattress?
If you tend to sleep hot, this mattress makes a strong case. The quilted top uses thermic polyester yarn with phase change materials, which means it absorbs heat and releases it back as your body temperature shifts, and the wool layer beneath is naturally breathable. The Talalay latex is elastic with excellent bounce-back, shaping around you and easing pressure at the hips and shoulders without that stuck-in feeling. Thicker gauge springs on the two outer rows give firmer edge support, useful if you sit on the bed to get dressed. Buying through MattressOnline, you get a 100-night trial and a 15-year guarantee, though those are the retailer's own terms rather than Dunlopillo's.
Key features & layer details
Quilted top panel
The top panel is woven with thermic polyester yarn featuring phase change materials, which absorb heat and release it depending on your body temperature. In practice that means a sleep surface that works to keep you at a steadier temperature through the night.
Latex comfort layer
Luxury Talalay latex, an elastic material with excellent bounce-back, shapes around your body and eases weight build-up on pressure points. You feel supported and cushioned without sinking in.
Wool comfort layer
A layer of plush wool fibres adds soft, natural comfort. Wool is naturally breathable and a good insulator, so it helps regulate temperature in both directions.
Pocket spring support system
A double layer of calico pocket springs, 2,340 in total, with each spring encased in its own individual calico cotton pocket so it adjusts to your body shape independently. Thicker gauge wire springs on the two outer rows firm up the edges.

Best suited for?
Warm sleepers
The quilted top has phase change materials that absorb and release heat, and the breathable wool layer beneath helps keep your temperature steadier through the night.
Side sleepers
Talalay latex shapes around your body and eases pressure at the hips and shoulders, so your shoulders and hips are cushioned without that stuck-in feeling.
Combination sleepers
The latex has excellent bounce-back, which means it responds quickly when you change position, so turning over during the night should feel easy.
Couples
Each of the 2,340 springs sits in its own calico pocket and adjusts independently, so the mattress can follow two different body shapes at once.
Back sleepers
A medium firm feel with a double layer of pocket springs gives steady support underneath you, while the latex layer adds cushioning without letting you sink in.
If you prefer a soft, enveloping feel, the medium to firm tension and bouncy latex will likely feel too resilient. Budget shoppers should look elsewhere: it is a premium purchase. It is also only listed in UK King, and being single-sided, it needs regular rotating rather than flipping.
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 Dunlopillo Elite Supreme 2340?
Dunlopillo describes it as medium to firm. The latex comfort layer softens the surface feel with responsive, bouncy pressure relief, while the double layer of calico pocket springs keeps overall support on the firmer side. Lightweight side sleepers may find it a little too firm.
Does the Dunlopillo Elite Supreme 2340 come with a trial and guarantee?
MattressOnline lists a 100-night trial and a 15-year guarantee with this mattress. These are the retailer's own terms rather than Dunlopillo's, so if you buy elsewhere, check what that retailer offers before ordering.
Is the Dunlopillo Elite Supreme 2340 good for hot sleepers?
It is well suited to warm sleepers. The quilted top uses thermic polyester yarn with phase change materials that absorb and release heat according to your body temperature, and the wool layer is naturally breathable. The pocket spring core also allows more airflow than an all-foam design.
Do you need to flip the Dunlopillo Elite Supreme 2340?
No. It is a single-sided mattress, so you rotate it end to end rather than flip it. That is slightly less effort than turning a double-sided mattress, though it does mean only one sleep surface takes all the wear.
How many springs does the Dunlopillo Elite Supreme 2340 have?
The product description states 2,340 springs across a double layer, with each one encased in its own calico cotton pocket to adjust to your body independently. Thicker gauge springs on the two outer rows provide edge support. The mattress is 33cm deep in total.
