What the product page shows
Mattress Online lists Mirapocket springs, an UltraGel comfort layer, zoned support and pressure-relieving foam, plus a medium to firm feel. The page also shows a 5.0/5 rating from 6 visible reviews, free delivery to most locations, old mattress removal, a 100-night comfort trial and a 5-year guarantee. That gives shoppers a clear mix of construction, service and confidence cues to compare, even though the review sample is small.
What the wider checks add
The most useful wider comparison point is price: at £425, the starting price sits below the comparable pocket sprung median of £569, which makes it more competitive than many similar options without pushing it into budget territory. The flip side is that model-specific public review coverage is thin, so the retailer and manufacturer descriptions carry most of the weight. That makes this a sensible comparison-led purchase rather than a mattress to buy on rating alone.
Buyer trade-offs to compare
The key trade-off is feel versus fit: a medium to firm pocket sprung mattress with zoned support is more structured than many foam-led options, but that will suit some sleep positions better than others. Back sleepers may appreciate the firmer, more supportive feel, while side sleepers may want to check whether the surface feels comfortable enough at the shoulder and hip. Before buying, compare your preferred firmness, the selected size, the mattress depth, and whether your bed frame, fitted sheets or topper can handle the finished height. Also check the 100-night trial terms carefully, including the swap-after-30-days rule and any exclusions, plus the latest delivery details at checkout.
Price and value benchmark
With tracked prices from £425 to £865, Silentnight UltraGel 1000 Mirapocket Mattress spans a fairly wide size-based range, so value depends heavily on which size you need. The single size starts below the peer median, while larger sizes move the spend up quickly, which is why the final checkout total matters more than the headline from price. The UltraGel comfort layer is worth noting here because it gives this model a clearer comfort-layer angle than a plain pocket-sprung mattress, but it is still something to compare rather than assume is better. Compare the chosen size against delivery, optional old mattress removal and any extra services before you judge value.
How it compares with nearby alternatives
If you want a similar Silentnight feel but a different price band, compare Silentnight Memory Cool 1000 Mirapocket Mattress, which starts lower at £369 and runs to £679, or Silentnight Lift Rejuvenate 1600 Pocket Mattress, which starts higher at £449 and reaches £1,009. Memory Cool may suit shoppers looking for a cheaper route into Silentnight pocket springs, while Lift Rejuvenate gives you a broader, pricier range to weigh up against this model’s UltraGel-led pitch. Use the same retailer logic for all three: size, firmness, depth and final delivered price.
How much weight to give the rating
The visible 5.0/5 rating is encouraging, but it comes from only 6 reviews, so it should be treated as supporting context rather than strong proof. That small sample can shift quickly with a handful of new comments, especially on a mattress that has multiple sizes and comfort-fit variables. If you want a more reliable decision, focus first on construction, firmness, depth and trial terms, then use the rating as a secondary reassurance check.
Who it suits
This model is most appealing to shoppers who want a medium-firm pocket sprung mattress with a more structured feel and a comfort layer aimed at pressure-relief positioning. The zoned Mirapocket springs, UltraGel layer and five size options make it a good fit for buyers comparing a mainstream Silentnight option against other pocket sprung choices, especially from Mattress Online where the current starting price is £425. It also makes sense if temperature comfort is part of your shortlist, provided you treat that as a comparison point rather than a promise.
Who should keep looking
If you want a softer feel, a clearly different construction, or a more price-led buy, this Silentnight UltraGel 1000 Mirapocket Mattress is probably not the first place to stop. Shoppers with tight space limits should verify the exact size and depth before ordering, because the mattress depth can affect bedding and bed-frame compatibility. It is also worth comparing other Silentnight models if you want a different spring count, a different firmness band or a simpler spec sheet.
Comfort and support
On Mattress Online, the Silentnight UltraGel 1000 Mirapocket Mattress is described with Mirapocket springs, zoned support, an UltraGel comfort layer and pressure-relieving foam, all in a medium to firm feel. In practical terms, that points to a more structured pocket-sprung mattress with a comfort layer that adds some surface give rather than a soft, sink-in build. The support system and comfort layer are useful comparison clues if you are weighing Silentnight against other pocket sprung mattresses, but they should be read as product descriptions rather than promises of pain relief or cooler sleep.
Value for money
Value looks reasonable rather than bargain-basement: the starting price of £425 sits below the peer median, but the larger sizes push the total up to £865. You do get five tracked sizes, a 5-year guarantee and a 100-night comfort trial, which helps justify the mid-range positioning if the fit is right. The best value check is whether the selected size, delivery option and any old mattress removal service still keep it competitive once you reach checkout.

Questions about this mattress
Is Silentnight UltraGel 1000 Mirapocket Mattress worth considering for a medium-firm feel?
Yes, if that firmness range suits your sleep preference. Mattress Online lists it as medium to firm with Mirapocket springs, zoned support and an UltraGel comfort layer, so it is aimed at shoppers who want a more structured pocket sprung feel rather than a soft, sink-in surface.
Does the price vary by size and what should I check before checkout?
Yes, tracked prices run from £425 for Single to £865 for Super King, so size makes a big difference. Before buying, confirm the chosen size is in stock, check the final checkout total, and review delivery costs or old mattress removal if you want those extras.
How reliable is the 5.0 rating if it only has 6 reviews?
It is a positive sign, but it is a small sample, so it should not carry too much weight on its own. Use the rating as supporting context and put more emphasis on firmness, depth, trial terms and whether the mattress size and price fit your needs.
Who is this mattress most likely to suit in practical terms?
It is most likely to suit shoppers looking for a medium-firm pocket sprung mattress with zoned support and a comfort layer that leans toward a more structured feel. If you want a Silentnight model at £425 and up, this one is worth comparing against nearby alternatives that sit in a different price band or use a different comfort mix.
What should I verify about the 100-night trial, guarantee and mattress depth before buying?
Check the exact 100-night comfort trial rules, including the swap-after-30-days detail and any exclusions, then confirm the 5-year guarantee wording on the retailer page. Depth matters too, because it can affect fitted sheets, toppers and bed-frame compatibility.
