Silentnight sells more mattress toppers than almost any other UK bedding brand, and the range has grown messy as a result. Airmax, Impress, Deep Sleep, Super Snoozer, Super Snuggly and the Heat Genie self-heating topper all sit on the shelf next to each other, and the naming does not make it obvious which one does what. Some are simple hollowfibre pads meant to freshen up a mattress that has gone slightly flat. Others are genuine memory foam layers built to change how a mattress feels. So which one do you actually need?
We went through the current lineup range by range, checking specs and prices against Silentnight’s own product pages and the listings at retailers including Argos, Amazon, Costco and MattressNextDay. Below is what each topper actually contains, what it costs, and which sleep problem it is realistically going to fix, so you are not guessing between near-identical product names at checkout.
What Matters Here
- Silentnight’s toppers split into two families: budget hollowfibre pads (Airmax, Deep Sleep, Super Snoozer, Super Snuggly) and genuine memory foam layers (Impress, in 5cm and 7cm depths).
- The Airmax range is the brand’s most-searched topper and comes in roughly 5cm, 8cm and 10cm depths, priced from around £32 for a single up to the mid-£40s for a super king in the 8cm version.
- A hollowfibre topper will soften a too-firm mattress and add a bit of loft. It will not fix sagging, lumps or a mattress that has genuinely worn out.
- Impress memory foam toppers cost considerably more and are the only Silentnight toppers built to relieve pressure points, though list prices vary wildly by retailer.
- The Heat Genie self-heating topper uses reflective foil and thermal lining rather than electricity, adding up to 7.5 tog for cold sleepers in winter.
- None of these toppers come from Silentnight with a sleep trial. Most carry a 2-year guarantee and can only be returned if faulty.
What’s actually in the Silentnight topper range right now?
The current lineup covers six distinct product families: Airmax (breathable hollowfibre, several depths), Impress (memory foam, 5cm or 7cm), and Deep Sleep Ultimate (quilted hollowfibre, 5cm or 10cm). Then there’s Super Snoozer (a thin budget pad), Super Snuggly (a deeper hollowfibre topper), and the Heat Genie self-heating topper for winter. Source: Silentnight

How much does the Airmax topper cost by size?
The standard Airmax topper (the 8cm dual-layer version) runs from £32 for a single up to £45 for a super king when bought directly from Silentnight, with each size step adding £3 to £9. It is the brand’s highest-volume topper by search demand, and the price ladder is one of the more consistent ones we found across sources.
Deeper Airmax variants, labelled 5cm or 10cm depending on the retailer, push the price up further. The 10cm version is often listed from the low £40s single to well over £80 for a super king at third-party retailers such as Amazon and Sleepy People. Worth the jump from the standard 8cm? Only if you specifically want extra loft, since the fill and construction underneath are otherwise the same. Source: PriceSpy UK
Is the Impress memory foam topper worth the extra money?
It is the only topper in the Silentnight range built from genuine memory foam rather than hollowfibre. That’s what makes it the only one that will noticeably relieve pressure on hips and shoulders, rather than simply adding softness on top.
That makes it worth the premium for back or side sleepers on a genuinely firm mattress, but not for anyone just wanting a plusher feel.
The 5cm Impress is listed at £86 (RRP £210.99) and the 7cm at £139 (RRP £356.99) through MattressNextDay, both with free delivery. Source: MattressNextDay
Both depths come with a removable cover that is machine washable at 40°C, are described as hypoallergenic, and carry a 2-year manufacturer’s guarantee. Source: Costco UK The 7cm option is also one of the few Silentnight toppers stocked at Costco, which is worth knowing if you already have a membership and want to avoid a separate delivery charge elsewhere.
What’s the difference between Deep Sleep, Super Snoozer and Super Snuggly?
These three are all budget hollowfibre toppers and the easiest ones to confuse. Deep Sleep Ultimate comes in 5cm and 10cm depths with internal quilted walls to stop the filling shifting. Super Snoozer is the thinnest and cheapest at roughly 2.5cm. Super Snuggly sits between the two, a 10cm hollowfibre layer with a simpler microfibre cover than the Ultimate range.
| Model | Depth | Typical price (single / double) | Notes |
|---|---|---|---|
| Deep Sleep Ultimate 500 | 5cm | From around £70 | Quilted cover, internal walls to hold shape |
| Deep Sleep Ultimate 1000 | 10cm | From around £65 | Reviewed as lightweight; only reaches full loft when unweighted |
| Super Snoozer | 2.5cm (3cm small double) | Budget tier, often discounted below £20 | Thinnest option, freshens rather than transforms a mattress |
| Super Snuggly 10cm | 10cm | £48 single / £58 double | Deeper hollowfibre fill than Deep Sleep or Super Snoozer |

The Ideal Home review of the Deep Sleep Ultimate 1000 is a useful reality check here. Its tester found the polyester microfibre fill only reaches its full 10cm loft when nobody is lying on it, and that it added softness without adding real support. That is a fair description of what any hollowfibre topper can and cannot do, whichever of these three you pick.
Does the Heat Genie self-heating topper actually work without electricity?
Yes, and it is a genuinely different product to the rest of the range rather than a heated topper with a plug. It uses a layer of heat-reflecting foil and thermal lining under a quilted top layer to bounce your own body heat back at you.
That adds up to 7.5 tog of extra warmth with no cables or power draw. Source: Silentnight
It fits with the same easy-fit elasticated straps as the rest of the range, is hypoallergenic, and comes with a 2-year guarantee. Silentnight’s own site prices it from £36 for a single, rising to £40 for a double directly from the manufacturer. Other retailers list it considerably higher, though, so it’s worth checking the official price first if you’re set on this one. It suits anyone who runs cold overnight, or who wants to turn the heating down without giving up a warm bed. Who won’t it help? Anyone whose actual complaint is a mattress that’s too firm rather than too cold.
Which topper actually fixes which sleep problem?
Match the topper to the specific complaint rather than the price tag. A hollowfibre topper changes how a bed feels on the surface. Only the Impress memory foam range changes how pressure is distributed underneath you, and nothing in the lineup adds structural support back to a mattress that has genuinely broken down.
| Problem | Recommended topper | Why |
|---|---|---|
| Mattress feels too firm | Airmax 8cm or 10cm, or Super Snuggly 10cm | Adds a soft layer without changing support |
| Hip or shoulder pressure pain | Impress Memory Foam, 5cm or 7cm | Only genuine memory foam layer in the range |
| Sleeping too hot | Airmax range | Air mesh sides specifically designed for breathability |
| Sleeping too cold in winter | Heat Genie | Reflective foil adds up to 7.5 tog without electricity |
| Tight budget, mattress just feels a bit tired | Super Snoozer or Deep Sleep Ultimate 500 | Cheapest way to add a fresh surface layer |
| Mattress sags, has lumps, or is genuinely old | None – replace the mattress | No topper restores lost support; see our best Silentnight mattress picks |
Do allergy sufferers need a specific topper?
Every current Silentnight topper we checked, from Airmax through to Heat Genie, is described as hypoallergenic and machine washable at 40°C. That means allergy sufferers are not restricted to one model in the way pressure-relief needs point specifically to Impress. Source: Silentnight
The practical difference for dust-sensitive sleepers is how often you are willing to strip and wash the cover, which is easier on a thinner topper like Super Snoozer than on a bulkier 10cm layer.
How do Silentnight toppers compare with buying a new mattress?
A topper is a genuine fix only when the mattress underneath is fundamentally sound and simply feels slightly firm, worn or cool. Independent buying guidance is consistent on this: a topper will not rescue a mattress that sags, has developed lumps, or has lost its support layer.
Trying to mask that kind of wear with a thick topper usually just delays a replacement you already need. Source: Consumer Reports buying guide
If your Silentnight mattress is past that point, a topper is the wrong purchase entirely. Our full Silentnight mattress review and honest assessment of whether Silentnight mattresses are any good both cover realistic lifespan expectations by range. Our Miracoil range review is worth reading first if you’re trying to work out whether a firmer feel is a topper problem or a mattress problem. Not sure which camp you’re in? That’s usually the first question worth answering before you spend anything.
Where can you buy Silentnight toppers, and does price vary much by retailer?
Yes, significantly. The same topper can differ in price by £50 or more between silentnight.co.uk, Argos, Amazon, Costco and MattressNextDay, and RRPs quoted by some retailers look designed to make a standard price look like a discount. Costco carries the 7cm Impress topper specifically, which needs a membership; the others sell the full range without one.
We cover the retailer landscape for Silentnight mattresses, including delivery times, returns and how to spot an inflated “was” price, in our separate guide to where to buy a Silentnight mattress. The same principles apply to toppers: check the current price at two or three stockists before assuming any one of them is the best deal. And use our Silentnight mattress size guide if you’re unsure which topper size actually fits your bed frame.
Your Questions, Answered
Can a mattress topper make a Silentnight mattress feel completely different?
A topper changes surface feel, not the mattress’s underlying support. Hollowfibre options like Airmax or Super Snuggly soften a firm surface; the Impress memory foam range is the only one that genuinely redistributes pressure. None of them will fix sagging or lumps.
How long do Silentnight toppers last?
Silentnight backs every current topper with a 2-year guarantee, but that covers manufacturing faults rather than a promise of lifespan. Hollowfibre fillings typically compress and flatten faster than memory foam with regular use and washing.
Do Silentnight toppers come with a sleep trial?
No. Silentnight’s 60 Night Comfort Exchange and 365 Night Sleep Trial apply to mattresses bought direct, not toppers. Source: Silentnight Toppers can generally only be returned if faulty, so check a retailer’s own returns window before buying.
What’s the difference between the Airmax 800 and Airmax 1000?
Retailer naming is inconsistent, but the numbers broadly track depth: the 800 is roughly an 8cm dual-layer topper and the 1000 is roughly 10cm. Check the depth stated in centimetres on the specific listing rather than relying on the model number alone, since we found the same product labelled differently across retailers.
Is the Silentnight Impress topper suitable for back pain?
It is marketed and sold as an orthopedic option for back and neck pressure relief, and it is the only memory foam topper in the range. That makes it the more credible pick of the two for pressure-related pain over a hollowfibre topper. It is not a substitute for a supportive mattress underneath it.
Can you wash a Silentnight mattress topper?
Most of the range has a removable cover that’s machine washable at 40°C, including Airmax, Impress, Deep Sleep and Super Snoozer. Always check the care label on the specific product, since fill type and cover material vary across the range.
