A good night's sleep is fundamental, but an uncomfortable mattress can often stand in the way. Whether your mattress is too firm, showing its age or causing you to wake up with aches, the cost of a full replacement can be substantial. A high-quality double mattress topper offers a practical and affordable way to transform your sleeping surface, enhance comfort and extend the life of your current mattress.
This guide is designed to help you navigate the options. We will outline the key factors to consider when choosing a double bed topper and present a few recommendations that balance comfort, support and value.
How to Choose the Right Double Bed Topper
Selecting the right topper involves more than just picking the first one you see. Consider these points to find a product that meets your specific needs.
Material Matters: Memory Foam vs. Microfibre
The material of a topper dictates its feel and function. The two most common options are memory foam and microfibre (or hollowfibre).
- Memory Foam: A memory foam mattress topper is known for its body-contouring properties. It responds to your body heat and weight, moulding to your shape to provide targeted support. This makes it an excellent choice for pressure relief, particularly around the hips, shoulders and back.
- Microfibre/Hollowfibre: These toppers have a softer, plusher feel, similar to a thick duvet. They add a layer of cushioning and are often a good choice if you simply want to soften a firm mattress without the distinct "sinking" feeling of memory foam. They are also frequently designed to be a washable bed topper, making maintenance straightforward.
Finding the Right Thickness: 2.5cm vs. 5cm
Thickness plays a crucial role in how much a topper will alter your bed's feel.
- A 2.5cm mattress topper provides a noticeable but subtle enhancement. It's ideal for adding a layer of softness to a mattress that is already in reasonable condition or for those who prefer a less dramatic change.
- A 5cm mattress topper offers a more significant transformation. This thickness provides substantial cushioning and is particularly effective for improving very firm or worn-out mattresses. It delivers a more pronounced level of pressure relief and comfort.
Key Features to Look For
Beyond material and thickness, a few other features can make a significant difference.
- Hypoallergenic Properties: If you suffer from allergies, a hypoallergenic mattress topper is essential. These are made with materials that resist common allergens like dust mites and mould, helping to create a cleaner sleeping environment.
- Secure Fit: Look for toppers with strong elasticated corner straps. This simple feature prevents the topper from shifting during the night, ensuring consistent comfort and saving you the daily hassle of readjusting it.
- Size: For a standard UK double bed, you will need a 135x200cm mattress topper to ensure a perfect fit from edge to edge.
Our Top Product Recommendations
Here are a few carefully selected options that cater to different preferences and needs.
MENDALE Soft Supportive 2.5cm Mattress Topper
- Why It Stands Out: This topper focuses on providing a simple, effective layer of soft support. Its key advantage is its practicality—it is fully machine washable, making it exceptionally easy to keep fresh and clean. The hypoallergenic filling adds another layer of assurance for a healthy sleep space.
- Pros:
- Machine washable for easy care.
- Hypoallergenic filling helps reduce allergens.
- Elasticated corner straps ensure a secure fit.
- Adds a noticeable layer of softness without being overly thick.
- Who is it for: Individuals or couples looking for a straightforward and affordable way to add a touch of plushness to their mattress. It is particularly suitable for students, renters or anyone who values easy maintenance.
MENDALE 5cm Memory Foam Mattress Topper
- Why It Stands Out: As a 5cm mattress topper, this model is designed for maximum impact. The thick memory foam construction excels at absorbing movement and contouring to the body, making it an effective pressure relief mattress pad. It can significantly improve the feel of an older or overly firm mattress.
- Pros:
- 5cm thickness for substantial comfort and support.
- Memory foam construction provides excellent pressure relief.
- Hypoallergenic materials.
- Can revitalise an uncomfortable mattress.
- Who is it for: Those seeking a significant upgrade in comfort, especially individuals who experience back or joint pain. It is an excellent choice for anyone wanting to transform a hard mattress into a much softer, more supportive surface.
MENDALE 2.5cm Memory Foam Mattress Topper
- Why It Stands Out: This topper offers a balanced solution, providing the pressure-relieving benefits of memory foam in a slimmer 2.5cm profile. It delivers noticeable contouring and support without the deep "sinking" sensation of a thicker foam topper, making it a versatile choice.
- Pros:
- Combines memory foam benefits with a less intrusive profile.
- Provides targeted pressure relief.
- Hypoallergenic design.
- A good entry point into memory foam products.
- Who is it for: Sleepers who want the contouring support of memory foam but prefer a firmer overall feel. It is also a great option for newer mattresses that just need a slight improvement in comfort and pressure distribution.

Frequently Asked Questions
Can a mattress topper make a firm mattress softer? Yes, this is one of the primary functions of a mattress topper. A topper made from soft microfibre or contouring memory foam adds a cushioning layer on top of your existing mattress, which can significantly soften a surface that feels too hard. A thicker topper (e.g., 5cm) will have a more pronounced softening effect.
How thick should a double mattress topper be? The ideal thickness depends on your goal. A 2.5cm topper is great for a subtle comfort boost and adding a touch of softness. A 5cm topper is better for a major comfort overhaul, providing deep cushioning and pressure relief, which is especially useful for older or very firm mattresses.
How do I stop my mattress topper from sliding? The most effective method is to choose a topper that comes with built-in elasticated corner straps. These straps hook under the corners of your mattress, holding the topper securely in place. For toppers without straps, you can place a tightly fitted sheet over both the topper and the mattress to help keep it from shifting.
