One To Avoid

Hokway 5cm Single Memory Foam Mattress Topper

Hokway 5cm Single Memory Foam Mattress Topper

We tested the Hokway 5cm Single Memory Foam Mattress Topper, and despite some promising features, it left us disappointed. The topper does offer targeted support for the back, hips, and shoulders, and its cooling gel layer helps maintain a cooler sleeping environment (a definite plus).

The bamboo cover is another highlight, as it’s breathable, machine-washable, and easy to maintain. However, these positives are overshadowed by significant drawbacks.

The decompression process was a major issue. Even after following the instructions to allow 72 hours for the topper to expand, noticeable folds and creases remained, severely impacting comfort.

The topper’s vacuum-sealed packaging seems poorly designed, leaving permanent ridges that never fully smoothed out.

Another serious concern was the overpowering odour upon unboxing. While some products have a mild "new foam" smell, this was intense and lingered for days. For those sensitive to odours, this could be a dealbreaker (it gave us headaches during testing).

Ultimately, while the Hokway mattress topper has potential, its flaws in expansion and lingering smell make it more trouble than it’s worth. We wouldn’t recommend this product unless these issues are resolved. There are far better options available in this price range.

How We Evaluated and Chose the Best Mattress Toppers on the Market

When identifying the best mattress toppers, we didn’t just rest easy on general claims. We meticulously examined every detail to ensure we found options that deliver comfort, durability, and value. Here’s how we approached the testing process.

Setup and Initial Impressions

We began by inspecting the packaging, ensuring each topper came with clear instructions and was sealed properly. Special attention was given to how well the toppers expanded after being unpacked and whether they developed any permanent creases.

Ease of setup was also critical, as was the presence and duration of any odours upon unboxing.

Comfort and Support

Testing for comfort meant focusing on how effectively the toppers provided pressure relief for key areas like hips, shoulders, and back. We evaluated performance across different sleeping positions—side, back, and stomach—to ensure versatility.

Additionally, we assessed firmness levels, motion isolation, and how well each topper conformed to the body for personalised comfort.

Temperature Regulation

We examined whether toppers trapped heat or provided a cool sleeping environment by testing them over several nights. Materials like gel-infused foam and breathable covers were evaluated for their ability to improve airflow and wick moisture.

Durability and Maintenance

Long-term usability was simulated by subjecting toppers to repeated use and checking for signs of wear and tear. We also evaluated the quality of removable covers for softness, durability, and ease of washing.

Features like elastic straps and anti-slip designs were tested to ensure the toppers stayed securely in place.

Fit and Versatility

Toppers were tested on a range of mattress types, including spring, memory foam, and hybrids, to determine compatibility. We also considered how easy it was to adjust or remove the toppers during regular use.

Certifications and Eco-Friendliness

We verified claims of safety and sustainability by checking certifications like CertiPUR-EU and OEKO-TEX. The environmental impact of materials was also considered, especially for eco-conscious consumers.

Value for Money

Finally, we compared the features and performance of each topper to its price. This included evaluating how well the topper maintained its comfort and support over time, ensuring that each choice offered long-term value.


Frequently Asked Questions

Will a Mattress Topper Make My Bed More Comfortable?

A mattress topper can significantly improve your bed’s comfort by adding a layer of cushioning or support. It’s ideal for revitalising older mattresses, adjusting firmness levels, or relieving pressure on key areas like the back and hips, making it a practical solution for enhancing sleep quality.

Can You Wash a Mattress Topper?

You can wash a mattress topper, but it depends on the material. Most toppers have a removable, machine-washable cover, while the inner foam or filling should be spot-cleaned. Always check the manufacturer’s instructions to ensure proper care without damaging the topper’s structure.

Is It a Good Idea to Buy a Mattress Topper in Place of a Mattress?

While a mattress topper can enhance comfort, it is not a replacement for a mattress. Toppers address surface-level issues like firmness but cannot fix a worn-out or sagging mattress. For long-term comfort and support, investing in a new mattress is essential.

How Many Inches of a Mattress Topper Is Best?

The best thickness for a mattress topper depends on your needs. A 2-3 inch topper is sufficient for minor adjustments, while a 4-5 inch topper provides enhanced support and cushioning for firmer or older mattresses. Thicker toppers are better for pressure relief and comfort.

Which Is Better, a Latex or Memory Foam Mattress Topper?

Choosing between a latex or memory foam mattress topper depends on personal preference. Latex offers a firmer, more responsive feel and is naturally hypoallergenic, while memory foam provides superior body contouring and pressure relief.

Both are excellent options, catering to different sleep needs and styles.


Final Word

Hopefully, our guide to the best mattress toppers in the UK has helped you find the perfect fit for improving your sleep. With so many choices, narrowing it down wasn’t easy, but we’ve highlighted the best for every need.

Our top pick is the Amazon Basics Comfort Memory Foam Topper, thanks to its ergonomic design, 7 cm of supportive memory foam, and eco-friendly certifications. It’s an excellent choice for upgrading older mattresses or adding comfort.

For versatility, the Bonnvia Thick Mattress Topper stood out with dual comfort levels and a breathable bamboo cover. Budget-conscious shoppers will appreciate the Silentnight Deep Sleep Mattress Topper, which offers great value without compromising softness.

However, the Hokway 5cm Single Memory Foam Mattress Topper was a disappointment, with poor expansion and a lingering odour overshadowing its positives.
