The Silentnight range: Miracoil, Mirapocket and the fillings above them
Miracoil is Silentnight's continuous, linked spring unit, listed by Dreams as traditional springs. Mirapocket uses individual pocket springs, with options ranging from fibre-filled Air Plus models to Memory, Easyflex Gel and UltraGel, plus pillow-top and box-top designs. The spring name doesn't tell you the firmness: there are softer and firmer choices within Mirapocket.
The wider catalogue includes Eco Comfort, Lift and Plant Based ranges, alongside children's mattresses and Dreams-only Eco Mirapocket models. Eco Comfort fibre gives a different surface feel from memory foam, latex or gel foam, so compare the fillings as well as the spring unit. The two Miras sound like siblings you keep calling by the wrong name. For a main double shared by two adults, leave Miracoil out of the shortlist.
If you're set on Silentnight, buy from the Mirapocket half: the SleepResponse Relieve 2000 leads my shortlist, and it's where I'd start at Dreams. For a side sleeper who wants more cushioning, the Support 3600 comes next, ideally bought in a sale.

- A child's bed or a cot
- The bed from the hotel
I think a name like UltraGel Cool-to-Touch 3000 Mirapocket Softer takes an impressive breath to say "medium, gel foam, pocket springs". Compare the pocket-sprung alternatives on their fillings and asking price. At equal money, that's where I'd send you. At Dreams, judge the price you'd actually pay rather than the sale sticker, and the shop itself is fine for lying on things.
Mirapocket is the half to buy if you're buying Silentnight anyway
Every Silentnight worth your time has pocket springs, and these are the ones. The medium-firm SleepResponse Relieve 2000 combines natural latex with pocket springs. On the Dreams floor, it eased pressure while supporting the back, and its CoolEase cover felt cool. When I lay on it at Dreams in October 2026, the surface stayed fresh the whole time and the support on my back was lovely, though at 61 kg I wanted more give at my shoulder on my side. Owners describe comfortable sleep. Initial sinking settled with rotation for one, while another initially preferred the one in the shop. This is where I recommend starting at Dreams.
For more cushioning, the medium Support 3600 felt lofty, secure at the lower back and easy to turn on during the visit. Owners are happy, and one warns that it is very deep. The very firm Breatheasy 1400 felt cool with springs responding to body shape: reserve it for a heavier back sleeper.
The firm Support 1400 felt right on the back in store, but several owners say the mattress that turned up was a lot harder than the one they'd lain on. One reports lost support within months. Reflex 1600's soft-medium gel top suited the side better than the back during testing. A couple report early sinking, and one a vinegar-like smell.
At Mattress Online, the firm Silentnight Air Plus 1000 Mirapocket Mattress suits a first flat or spare room, though several owners dispute its former medium label and a couple report early sagging or springs felt at the sides.
The Silentnight Easyflex Gel 3000 Mirapocket Box Top Softer Mattress and both UltraGel Cool-to-Touch models carry box tops or pillow tops, happy Firmer owners or not, so none of the three makes my list. A couple of owners of the Easyflex Gel model report troughs within weeks. I drink iced coffee even in January, despite knowing the caffeine advice, so I understand the attraction of "cool". Count the minis as cushioning and judge the mattress on the springs beneath them.
The Silentnight Air Plus 1400 Mirapocket Ortho Mattress is extra firm, with dipping and missing-handle complaints. The Silentnight Portchester 1000 Pocket Eco Pillow Top Mattress and Silentnight Newbury 1000 Pocket Eco Pillow Top Mattress are pillow tops too, which settles them for me. A couple of owners report ridged toppers on the Portchester and several report early dips on the Newbury. The two Miras were the easy part; the mattress names take longer.
Miracoil gets my open-coil verdict
Keep this linked-spring range to a tight budget or occasional guest bed, and in a firmness most guests could sleep on. Mattress Online files Miracoil alongside open-coil mattresses. Extra-firm versions suit too few people for guests, and a main bed calls for pocket springs.
The extra-firm Ortho Dream Star has reports of felt springs from several owners, squeaks from a couple and slumps within months from a few. Owners of the Silentnight Vilana Miracoil Mattress disagree about firmness, and one describes an air-mattress feel. With the two Miras, those final letters are worth reading twice. Happy budget owners wanted firm and cheap and got both.
Miracoil Pillowtop felt good on the back during testing, and it's still a pillow top, so leave it in the shop.
Children get pocket springs, while bunks require the right depth
For a child's main single, buy a new children's mattress with pocket springs: the medium Silentnight Kids 600 Mirapocket Mattress, Brave, Achieve or Silentnight Adventure Natural Kids' Pocket Sprung Mattress. The Silentnight Believe Memory Kids' Traditional Spring Mattress uses Miracoil with memory foam, so choose the pocket-sprung options instead.
The Silentnight Kids Bonnell Bunk Mattress, Silentnight Kids Bonnell Quilted Mattress, Eco Waterproof Bunk, Play and Explore use traditional open-coil units. On a top bunk, thin is correct: the mattress has to stay under the bunk's marked depth limit, because every extra centimetre of mattress takes a centimetre off the rail above the child. Never add a topper or extra padding. Eco Waterproof has a waterproof side. Several owners of the Silentnight Kids Bonnell Bunk Mattress say their children sleep well on it, one reports discomfort, and an Eco Waterproof Bunk owner found rough stitching.
The Silentnight 70 x 140cm Safe Nights Snuggle Cot Bed Mattress and Lullaby have firm polyester fillings and removable washable covers. Fairytale is firm with a washable cover. I tried the Silentnight 70 x 140cm Safe Nights Snuggle Cot Bed Mattress on the Dreams shop floor and found it firm, noticeably cool and breathable. One owner reports a good cot-bed fit and no chemical smell. Follow the Lullaby Trust's advice: a firm, flat mattress with a waterproof cover, and check it fits the cot properly.
Premier Inn's mattress wears a different label over Silentnight components
The Premier Inn Mattress 2.0 uses Mirapocket springs and Geltex, with a medium-firm feel and 28.5cm depth. Its zip-off pillowtop topper can be rotated by one person, and it's still a pillow top, which isn't my construction. The listing states an anti-bed-bug finish with permethrin as its active ingredient. Several owners say it feels unlike the hotel bed. One reports early dents, and one sagging on both sides.
Happy owners bought after enjoying a hotel night. A new, firm-ish bed that someone else made has advantages beyond its fillings. Compare hotel-style mattresses by construction; breakfast arriving without your involvement isn't included.
Furniture Village's exclusive Revitalise range includes firm Refresh 800 at 27.5cm, extra-firm Ortho 1400 at 25.5cm and medium Breathe 3000 Pillowtop at 34cm. Breathe combines 2000 pocket springs with 1000 minis and ActiveBreathe fibre, Silentnight's memory-foam alternative. In store, its top cushioned hips and shoulders with controlled back support, without feeling noticeably cool. A pillow top again, so not for me. One Ortho owner reports a first-night indentation. Furniture Village prices this counter the way it prices most things: high.
For the Payton frames at Dreams, inspect support first: solid slats on the plain frame, sprung slats and end-opening storage on the ottoman. The pillows are a hollowfibre pair at Mattress Online and two options at Dreams, including memory foam.
