Silentnight Mattress Reviews

Across the group, Silentnight’s personality shows up most clearly in its support systems. The Miracoil build feels straightforward and budget-minded, while the pocketed models add more isolation and a cleaner support line.

On my log, Eco Comfort Pocket 1200 was the most dependable ‘workweek’ bed. It stayed firm through the middle without feeling harsh, which kept my lower back from dipping on long reading nights.

Marcus (our heaviest tester) quickly separated the pack. The Miracoil Memory Cushion Top felt warm and sank more under his hips, while Eco Comfort Breathe 2000 Pocket held him higher and stayed more temperature-neutral.

Mia’s side-sleeper notes favored the softer top feel of Geltex Ultra 3000, especially around shoulders and hips. For couples, Jenna and Ethan preferred the pocket builds for calmer partner movement, while Jamal cared most about how easily he could move and stretch without feeling stuck.

We used the same scoring grid we apply to most mainstream mattresses: support, pressure relief, cooling, motion isolation, responsiveness, edge support, materials/eco profile, and value. Each category is scored on a 3.0–5.0 scale.

The routine mixes structured checks with normal sleep. We photographed alignment on back, side, and stomach, ran partner-movement drills, and did edge sit tests for getting dressed and tying shoes.

Most importantly, everyone logged full nights—not just quick studio sessions. Morning notes covered temperature, wake-ups, and any aches by body area, then we compared those notes against how each bed is built.

Our Testing Experience

The Miracoil Memory Cushion Top is the simplest bed in this set: a Miracoil spring unit with a thin memory-foam comfort layer. Lying on my back, I felt decent lift under the lower back at first, but the top warmed up after a couple of hours.

Marcus exposed the limits fast. Under his weight, the middle softened more and he woke up warmer than on any of the pocket-spring options.

For lighter sleepers, the feel was more predictable. Mia liked the initial comfort, but still called out heat build-up as the night went on.

Partner movement is the weak spot. In our couple drills, the open-coil style response carried Ethan’s entries across the surface, and edge sit support dropped off noticeably for heavier testers.

Review Score

Our Testing Experience

Eco Comfort Pocket 1200 was the most ‘no drama’ mattress in the lineup. On my back, the pocket springs held my hips steady without pushing my shoulders up, and the surface stayed fairly breathable night to night.

Carlos wrote the same thing in fewer words: stable, level, and easy to live on during workweeks.

For Mia, the top fibers felt a little springy. She didn’t sink far enough to get that deep shoulder pocket she prefers, even though her alignment stayed clean.

Couple testing landed in the middle: less partner motion than Miracoil, more awareness than the higher-spring-count models.

Pros & Cons

Details

• Price: ~£350–£550 for a double (varies by retailer)
• Firmness: Medium-firm, around 6.5/10
• Type: Pocket springs with Eco Comfort fiber layers
• Height: Approximately ~24–26 cm
• Cooling: Good airflow compared with memory-foam-topped options
• Motion isolation: Moderate-high for most couples
• Best for: Average-weight back sleepers and combination sleepers who want a firmer core

Review Score

Our Testing Experience

Eco Comfort Breathe 2000 Pocket felt denser and more planted than the 1200 version. On my back, the surface stayed steady through the hips, and temperature stayed more neutral than the foam-topped options.

Marcus liked this one for exactly that reason: it kept his midsection higher and didn’t trap heat the way the Miracoil model did.

Mia still wanted a softer shoulder pocket, but she did last longer here than on the 1200 before noticing pressure.

In partner tests, the higher spring count muted impact well. You can still sense a partner moving, but it’s less likely to jolt you awake.

Pros & Cons

Details

• Price: ~£550–£750 for a king (varies by retailer)
• Firmness: Medium to medium-firm, roughly 6–6.5/10
• Type: Pocket springs with breathable Eco Comfort ‘Breathe’ fiber layers
• Height: Approximately ~31–32 cm
• Cooling: One of the strongest performers in this group
• Motion isolation: High for a springy build
• Best for: Hot sleepers, couples, and average-to-heavier combination sleepers

Review Score

Our Testing Experience

Geltex Ultra 3000 is the most comfort-forward bed we tested. The surface has more give at shoulders and hips than the Eco Comfort models, but it doesn’t feel like slow, sticky memory foam.

Mia’s pressure-map sessions improved the most here. Her shoulder area looked calmer, and she reported fewer ‘joint awareness’ wake-ups.

Marcus was cautious about the softer top, but the spring core still kept him from sinking into a hammock. He did note it’s less ideal for long stomach-sleep stretches.

Cooling was solid for a plusher build, and partner movement stayed controlled. The main trade-off is the heavier, thicker profile—moving it takes effort.

Pros & Cons

Details

• Price: ~£650–£900 for a king (varies by retailer)
• Firmness: Medium to medium-firm, roughly 6–6.5/10
• Type: Pocket springs with a Geltex comfort layer and plush quilting
• Height: Approximately ~36 cm
• Cooling: Good airflow compared with dense memory foam
• Motion isolation: High with a more cushioned feel
• Best for: Side sleepers, joint-sensitive sleepers, and couples who want a calmer surface

Our Testing Experience

Studio Memory Hybrid is the convenience pick: it arrives boxed and expands quickly, which matters in tight stairwells and smaller rooms. The feel landed around medium—soft enough to take the edge off, but not a deep sink.

Jenna and Ethan found partner movement damped out faster than on the Miracoil model. You can feel activity, but it settles quickly.

Carlos liked the overall balance, but still preferred the more structured pocket-spring feel of Eco Comfort Pocket 1200 for strict back-sleeping weeks.

For Marcus and Jamal, the trade-off was clear: easy mobility for a boxed hybrid, but softer edges when sitting to get dressed.

Pros & Cons

Details

• Price: ~£450–£650 for a king (varies by retailer)
• Firmness: Medium, around 6/10
• Type: Boxed hybrid with pocket springs and foam comfort layers
• Height: Approximately ~25–27 cm
• Cooling: Moderate; cooler than all-foam, warmer than fiber-only builds
• Motion isolation: High enough for most couples
• Best for: Renters, apartment living, and shoppers who prioritize easy delivery

Review Score

Start with three variables: your sleep position, your body weight, and how easily you overheat. Then factor in logistics—especially whether you need a boxed mattress for stairs or tighter spaces.

If you’re a lighter side sleeper who notices shoulder pressure, Geltex Ultra 3000 is the most forgiving top in this set. If you want a lower price, Studio Memory Hybrid plus a soft topper can help, but it won’t match the Geltex feel.

If you’re an average-weight back sleeper who wants a firmer core, Eco Comfort Pocket 1200 is the simplest match. If you rotate positions and run warm, Eco Comfort Breathe 2000 Pocket adds airflow and a steadier platform.

If you sleep hot, lean toward the fiber-heavy pocket models first. In our logs, Eco Comfort Breathe 2000 Pocket stayed the most consistently cool, with Geltex Ultra 3000 close behind for a plusher build.

For couples and heavier bodies, prioritize the pocket models for cleaner support and calmer movement. Studio Memory Hybrid can still work for convenience-driven buyers, but expect softer edges if you sit on the perimeter often.

In our testing, the pocket-spring models were the most consistent for back comfort. Eco Comfort Pocket 1200 and Eco Comfort Breathe 2000 Pocket kept our spines closer to neutral than the Miracoil option, especially for back sleepers.

Geltex Ultra 3000 made the biggest difference for side sleepers on our team, particularly around shoulders and hips. If you want a firmer, cooler surface, Eco Comfort Breathe 2000 Pocket is the next best fit.

It depends on the build. The Miracoil memory-style model ran warmest in our logs. The fiber-forward pocket models slept cooler overall, and Geltex Ultra 3000 stayed reasonably temperature-neutral for a plusher bed.

Durability depends on body weight, base support, and rotation habits. In general, the pocket models in this set felt better equipped for daily use than the entry Miracoil option, while the thicker Geltex build should hold up well with regular care.

For calmer nights with a partner, the pocket models performed best for us. Geltex Ultra 3000 and Eco Comfort Breathe 2000 Pocket reduced disruptive movement, with Studio Memory Hybrid close behind for a boxed option.

Heavier sleepers generally do better on pocket-spring designs than on simpler open-coil builds. Eco Comfort Pocket 1200 and Eco Comfort Breathe 2000 Pocket held our heavier tester’s hips higher and felt more stable through the middle.

All five worked on solid and closely spaced slats in our checks. Adjustable bases are usually easiest with rolled or moderate-profile designs; thicker, heavier mattresses can be less convenient depending on the frame.

Rotation schedules vary by model, but regular head-to-foot rotation helps keep wear even—especially in the first few months. One-sided pillow-top designs still benefit from rotation even if they can’t be flipped.

Studio Memory Hybrid delivered respectable support for a boxed mattress, but it felt less structured than Eco Comfort Pocket 1200 in our back-sleep checks. If you need the firmest, most stable feel, the pocket-spring models are safer bets.

Eco Comfort Pocket 1200 hit the best balance in our scores: strong support, good cooling, and solid motion control at a mid-range price. Eco Comfort Breathe 2000 Pocket adds cooling and stability at a higher cost.
