We compare the Otty Hybrid Mattress and the Silentnight Ortho Dream Star Miracoil to help you decide which belongs in your bedroom.
These two mattresses sit at very different points of the market. The Otty Hybrid is a 25cm deep hybrid with six layers, combining heat regulating memory foam with up to 2,000 encapsulated pocket springs. The Silentnight Ortho Dream Star is a simpler 22cm mattress built around Miracoil open coil springs with an Eco Comfort Fibre layer on top, and it is rated Extra Firm rather than the Otty's Medium-Firm 7/10.
Our verdict is clear: the Otty Hybrid wins this comparison. It takes the construction, layers, value and terms dimensions, with a taller spring layer, a deeper build, a longer guarantee and a firm 100-night trial from the maker. The Silentnight fights back on certifications, but that's a narrow win.
That said, the Silentnight is the better pick for a specific reader: anyone who genuinely wants an extra firm surface, particularly back sleepers with aches. Below, we set out who should choose which.
Our verdict at a glance: which mattress wins?
The Otty's deeper hybrid construction, with 16cm encapsulated pocket springs, better terms and stronger value for its type, decides it.
WINNER
Taller pocket springs with less motion transfer
The 16cm encapsulated pocket springs give genuine bounce and support while minimising motion transfer, which means a restless partner disturbs you less than the Silentnight's open coil design would.
Stronger trial and guarantee terms
Otty offers a 100-night trial and a 10-year guarantee directly, where Silentnight's trial varies by retailer and its guarantee runs to 5 years.
Better value against its peers
The Otty sits slightly below the typical price for a hybrid of this build, while the Silentnight is priced well above the norm for an open coil mattress.
RUNNER UP
An extra firm feel the Otty can't match
If you want a genuinely rigid surface, the Miracoil system's zoned support holds your spine in line, and across verified owner reviews sleepers with back issues rate it highly for exactly that.
Recycled, sustainable comfort materials
The Eco Comfort Fibre layer is made from recycled materials and 100% sustainable sources, and the mattress is vegan-friendly, hypoallergenic and handcrafted in the UK.
A lower price of entry
The Silentnight comes in noticeably cheaper than the Otty, which matters if budget is your first concern.

The Otty takes construction comfortably. Its six layers run 25cm deep, with 16cm encapsulated pocket springs, memory foam and airflow side supports that give an edge-to-edge sleeping surface. The Silentnight's three-layer, 22cm open coil build is honest and simple, but pocket springs isolate movement better than Miracoil coils, so couples in particular will feel the difference.

Which mattress feels better?
<p>The Otty is rated Medium-Firm, 7/10, which means noticeable support with a softer knitted surface on top rather than a sink-in feel. That suits back and front sleepers who need spinal support, though lightweight side sleepers may find it a little too firm on shoulders and hips.</p><p>The Silentnight is Extra Firm, and it makes no apology for it. Its zoned Miracoil springs give firmer resistance where your body is heaviest, so heavier sleepers and back sleepers get proper alignment. Side sleepers, especially lighter ones, should steer clear of the Silentnight entirely; if you're between the two, the Otty is the more forgiving surface.</p>
Other important factors to consider before buying.
Aftercare terms separate these two more than most pairs. Otty backs its hybrid with a 100-night trial and a 10-year guarantee, while the Silentnight's trial varies by retailer and its guarantee is 5 years. The table below sets it out side by side.

Do bear in mind that as these mattresses come delivered in sealed boxes they will have a rubbery smell when first extracted. They need a good few hours in a room with the windows open before you sleep on them.

The Otty Hybrid is the winner here, and it wins on the dimensions that matter most: construction, layers, value and terms. Its 25cm, six-layer build with 16cm encapsulated pocket springs offers better motion isolation and firmer edges than the Silentnight's simpler open coil design, and the 100-night trial with a 10-year guarantee is a far stronger safety net than a retailer-dependent trial and 5 years of cover. It's also well priced against other hybrids, where the Silentnight costs more than most open coil mattresses do. The one clear reason to buy the Silentnight instead is its Extra Firm feel. If you have back trouble and want a rigid, zoned surface at a lower outlay, it serves that need honestly. For most sleepers, though, the Otty is the better buy.
Decision helper
Consider your primary need: a balanced medium-firm hybrid with strong trial and guarantee terms, or a cheap, genuinely extra firm mattress for a rigid sleeping surface.

Is the Otty Hybrid or the Silentnight Ortho Dream Star better for back pain?
Both support the back, but differently. The Silentnight's Extra Firm Miracoil springs use separate support zones to hold the spine in line, and across verified owner reviews sleepers report reduced aches. The Otty's Medium-Firm 7/10 hybrid build suits back sleepers who want support with a slightly softer surface. If you need a truly rigid feel, choose the Silentnight.
Which is better for couples, the Otty Hybrid or the Silentnight?
The Otty is the better choice for couples. Its encapsulated pocket springs are designed to minimise motion transfer, so a restless partner is less disruptive, and the side supports give an edge-to-edge sleeping surface. The Silentnight's open coil design means couples may notice more movement transfer across the bed.
Do the Otty Hybrid and Silentnight Ortho Dream Star come with a trial?
The Otty comes with a 100-night trial run by Otty directly, plus a 10-year guarantee. The Silentnight has no manufacturer trial, so any trial period varies by retailer, and its guarantee is 5 years. If the option to return matters to you, the Otty's terms are clearly stronger.
Is the Silentnight Ortho Dream Star too firm for side sleepers?
Very likely, yes. It's rated Extra Firm, and lighter side sleepers in particular will find it hard on shoulders and hips. The Otty, at Medium-Firm 7/10, is the more forgiving of the two, though even it may feel a little firm for lightweight side sleepers who prefer a plush feel.
Which sleeps cooler, the Otty Hybrid or the Silentnight?
Both make cooling claims and neither has a clear edge. The Otty uses heat regulating memory foam and airflow side supports to aid temperature regulation, while the Silentnight pairs breathable Eco Comfort Fibre with a damask cover that doesn't retain heat. Warm sleepers shouldn't rule out either on temperature alone.
