There’s a simple truth: not every mattress is perfectly comfortable. But replacing it entirely isn’t always an option. That’s where mattress toppers step in, and few products promise instant comfort like the Comfort Boost Plus Mattress Topper from The Mattress Topper Company. Designed with UK sleepers in mind, this topper seeks to transform the average or ageing mattress into a plush, supportive haven—without breaking the bank.
This in-depth review examines the Comfort Boost Plus Mattress Topper, its features, who will benefit the most from it, and why it could make a real difference to your sleep. Whether you’re hunting for extra softness, hypoallergenic bedding, or a cost-effective way to revitalise your bed, read on to see if this is the topper your nights have been missing.
Product Overview: What Is the Comfort Boost Plus?
The Comfort Boost Plus is a generously filled mattress topper manufactured by The Mattress Topper Company and sold through Mattress Online. It’s available in various sizes, with this review focusing on the super king (6′ x 6’6″ or 180 cm x 200 cm) option. Retailing at £54.95 (RRP £79), it sits firmly in the affordable zone for quality toppers in the UK.
Its main purpose? To offer an immediate upgrade in the softness, comfort, and overall feel of any standard mattress, while protecting it from wear and tear. It caters to anyone who wants a budget-friendly comfort boost, and comes with several key benefits you’d expect from a modern sleep accessory.
Key Features
Deep Hollowfibre Fill
At the core of the Comfort Boost Plus is a thick layer of hollowfibre filling. This synthetic material is well-loved in the bedding industry for its blend of softness and resilience. Hollowfibre is designed to trap air, creating a plush, ‘cloud-like’ sensation and an even distribution of support across your body.
Generous Profile for Noticeable Comfort
The topper boasts impressive loft, so you truly feel the difference from your very first night. Its deep fill provides an effective buffer, softening mattresses that feel too firm or lumpy. For many sleepers, this alleviates pressure points on hips and shoulders, often leading to a better night’s rest.
Hypoallergenic and Allergy-Friendly
If you’re prone to allergies, the hypoallergenic properties of this topper are worth noting. The Comfort Boost Plus is constructed from synthetic fibres that are resistant to common allergens like dust mites, making it a safer choice for asthma and allergy sufferers seeking undisturbed sleep.
Machine Washable for Easy Care
Unlike some memory foam or feather toppers, the Comfort Boost Plus is entirely machine washable—an essential for anyone wanting both hygiene and convenience. Simply pop it in your machine when spills, allergies or dust accumulate, and enjoy a fresh, clean sleep surface again and again.
Stays Secure on Your Bed
Elastic corner straps are included to keep the topper securely in place through the night. No sliding, bunching, or re-adjusting needed—simply fit it and forget it.
Affordable, Accessible Comfort
With a price point under £55 for the super king model, the Comfort Boost Plus offers a significant sleep upgrade at a fraction of the price of a new mattress. It’s a popular choice for students, renters, guest bedrooms, and anyone not ready to commit to a full mattress replacement.
Who Should Consider the Comfort Boost Plus?
The Comfort Boost Plus Mattress Topper is suitable for a wide variety of sleepers and situations. You’ll particularly benefit if:
- Your current mattress feels too firm, tired, or uneven
- You’re experiencing discomfort, aches or pressure points at night
- You want to refresh a guest bed or holiday let without investing heavily
- You have allergies or want a bedding layer that’s easy to wash
- You’re a student, renter, or anyone in temporary accommodation needing an affordable comfort fix
- You want your expensive mattress to last longer by protecting it from everyday wear and spills
If your mattress is severely sagging or damaged, a topper can help but won’t magically fix structural issues. In these instances, look to full mattress replacement guides, such as our comparison of the best mattresses in the UK for more suitable options.
How Does the Comfort Boost Plus Feel?
The first impression most sleepers report is immediate plushness and a cosy, cushioned feeling. Hollowfibre creates a ‘soft hug’ effect, meaning pressure relief is excellent without that sinking sensation sometimes associated with memory foam. It’s well suited for those who enjoy a gentle, yielding touch but don’t want their bodies to overheat.
The topper’s lofty design also traps air, contributing to a sense of breathable comfort throughout the night. Because the fill is synthetic, it’s less prone to compressing quickly (as can happen with down or feather toppers) and regains its shape with a quick shake.
Firmness and Support
While the Comfort Boost Plus is designed to create a soft sleeping surface, it doesn’t sacrifice support altogether. In most cases, it leaves sleepers feeling noticeably more supported than a tired spring mattress alone. That said, it won’t turn an ultra-firm mattress into a soft one, or provide the orthopaedic firmness some back pain sufferers need.
If you require more targeted support or a hybrid feel, consider reading our reviews of hybrid mattresses or orthopaedic models.
Hypoallergenic Properties: Peace of Mind for Allergy Sufferers
Allergy sufferers know the frustration of waking up due to sneezing fits or itchy eyes. The Comfort Boost Plus is a valuable tool in this fight. Its hollowfibre filling doesn’t harbour dust mites, skin flakes, or bacteria the way traditional fillings might.
For extra hygiene, being machine washable means you can freshen it up whenever you sense allergens building up. Many customers find symptoms ease simply by adding this topper to their beds—and regular washing keeps it effective long-term.

Maintenance and Longevity
One of the clearest advantages over other comfort upgrades is the Comfort Boost Plus’s maintainability. Unlike memory foam or latex, it doesn’t require specialist cleaning—just pop it in the washing machine, then tumble dry low or air dry. Regular fluffing helps maintain that billowy feel and prevents the fibres from matting down.
With proper care, it stands the test of time much better than cheap microfibre or budget egg crate toppers. Users generally report durability for several years, especially in guest rooms or with occasional use.
Fit and Sizes
This topper comes in a range of sizes, but the super king version offers plenty of coverage for larger mattresses at 180cm x 200cm. Its deep skirt and elasticated corners fit snugly over any standard-depth mattress. The generous sizing ensures edge-to-edge cushioning, with no uncomfortable gaps at the sides or foot.
If you’re shopping for a different size, the topper is often available in single, double, and king to suit any bed configuration.
How Easy Is It to Set Up?
Installation is refreshingly straightforward. Unbox, shake out, and lay the topper flat on your mattress. Simply loop the elastic straps around each mattress corner to lock the topper in place. A few hours’ airing will fluff up the filling, after which your bed is ready for linen and sleep.
There’s no ‘off-gassing’ or lingering chemical smell, unlike some memory foam mattress toppers. You can sleep on it the first night with complete confidence.
Price and Value
The Comfort Boost Plus Mattress Topper is priced at £54.95 for the super king size at the time of review (RRP £79). For a high-loft, hypoallergenic and washable product from a reputable retailer like Mattress Online, this offers significant value for money. Comparable toppers with similar features often cost considerably more in UK bedding shops.

Comparison: How Does It Stack Up?
Compared to other toppers in this price range, the Comfort Boost Plus stands out for a few reasons:
- Plushness: Its hollowfibre fill is noticeably thicker and more comfortable than basic microfibre toppers.
- Easy Care: Full machine washability is a feature not all toppers at this price point can boast.
- Hypoallergenic: It’s a safe choice for those with mite or dust allergies.
- Secure Fit: Reliable elastic straps mean the topper stays put, even for restless sleepers.

What Are Customers Saying?
The Comfort Boost Plus consistently attracts favourable reviews for:
- Noticeable improvement in comfort, especially on firmer or older mattresses
- Ease of laundering and maintenance
- Robustness of elastic straps and topper construction
- Good allergy performance
Some users would appreciate more density for long-term use, particularly those seeking heavy-duty support for back pain. For most, though, it offers an immediate and cost-effective comfort upgrade.
Is It Worth It?
If your aim is to make an existing mattress more comfortable without spending hundreds on a new one, the Comfort Boost Plus is an excellent investment. Its plush hollowfibre fill, easy maintenance, and secure fit tick all the right boxes for UK shoppers wanting an instant sleep upgrade.
It won’t transform a completely worn-out or collapsed mattress—no topper can—but it makes the vast majority of average, firm, or slightly past-their-best mattresses feel noticeably better. That makes it especially valuable for students, renters, guest rooms, and anyone looking to extend the lifespan of a decent bed.
Care Tips for Long-Lasting Comfort
- Air your topper for several hours before first use
- Wash once every few months or as needed for allergies
- Fluff by hand after drying to maintain loft
- Use with a quality mattress protector for even better hygiene and mattress longevity
