A good night's sleep is fundamental, but a mattress that feels too firm, has lost its comfort or is simply an investment you want to protect can stand in the way. Replacing a mattress is a significant expense. A high-quality mattress topper or protector offers a practical and affordable way to transform your bed's comfort and extend its lifespan.
Whether you're looking to add a layer of plush softness, gain targeted pressure relief or shield your mattress from spills and allergens, the right topper can make all the difference. This guide is designed to help you navigate the options and find a suitable match for your needs, from a single mattress topper for a child's room to a luxurious king-size upgrade.
A Practical Guide to Choosing Your Mattress Topper
Making the right choice comes down to understanding your primary goal. Are you seeking comfort, protection or a bit of both? Here are a few key points to consider.
Material Matters: From Comfort to Protection
The material of a topper dictates its feel and function.
- Memory Foam: A memory foam mattress topper is known for its ability to contour to your body's shape. This provides excellent support and pressure relief, particularly for side sleepers or those with joint discomfort. It absorbs movement, which is a benefit if you share a bed.
- Quilted Microfibre/Hollowfibre: For those who find their mattress too firm, a quilted mattress topper filled with materials like hollowfibre offers a plush, cloud-like surface. These are often designed with box-stitching to keep the filling evenly distributed and prevent clumping.
- Waterproof Membranes: A waterproof mattress protector is less about changing the feel of your mattress and more about preserving it. Modern designs often feature a soft cotton or terry cloth surface with a breathable yet impermeable layer underneath. This protects against liquids, dust mites and allergens without causing overheating or making noise.
Thickness and Density: Finding Your Comfort Level
The thickness of a topper directly impacts how much it will alter your sleeping surface.
- 2-4 cm: Thinner toppers provide a subtle layer of softness or protection without dramatically changing the mattress's underlying support.
- 5-8 cm: A thick mattress topper in this range can significantly transform your bed. A 5cm memory foam topper can add substantial contouring and pressure relief, while an 800GSM quilted topper will create a deep, plush feel.
Getting the Size Right
Ensure you match the topper to your mattress size. Standard UK sizes like single mattress topper (90x190cm), double mattress topper (135x190cm) and king size mattress topper (150x200cm) are widely available. A correctly sized topper with secure fittings, like deep elasticated skirts or corner straps, will prevent it from shifting during the night.
Our Top Product Recommendations
As your Joybuy Product Recommendation Officer, I've filtered through various options to highlight a few standout products that address different needs and preferences.
For Ultimate Mattress Protection: LeBonsoir 100% Cotton Waterproof Mattress Protector
- Why It Stands Out: This protector prioritises hygiene and preservation without compromising comfort. Unlike crinkly plastic sheets, it features a soft, 100% cotton terry surface that is quiet and breathable. The waterproof membrane beneath effectively blocks liquids while allowing air to circulate, helping to maintain a comfortable sleep temperature.
- Pros:
- Fully waterproof barrier protects against spills, stains and allergens.
- Breathable membrane prevents overheating.
- Crinkle-free and silent for an undisturbed sleep.
- Machine washable up to 60°C for high-level hygiene.
- Secure four-corner elastic straps fit a range of mattress depths.
- Who is it for? Ideal for families with young children, pet owners, allergy sufferers or anyone wanting to protect their mattress investment from daily wear and tear. It's also a practical choice for guest rooms and care facilities.
For Cloud-Like Softness: NightComfort Quilted Microfibre 800GSM Topper
- Why It Stands Out: This is a genuinely thick mattress topper designed for maximum plushness. The high 800 GSM (grams per square metre) hollowfibre fill provides a deep, springy layer of comfort. Its box-stitched pocket design ensures the filling stays evenly distributed, providing consistent softness across the entire bed.
- Pros:
- Transforms a firm or old mattress with a luxurious, soft feel.
- High-density 800 GSM fill offers substantial cushioning.
- Box-stitch construction prevents filling from shifting.
- Soft microfibre cover enhances the cosy feel.

For Contouring Pressure Relief: MENDALE 5cm Memory Foam Mattress Topper
- Why It Stands Out: This pressure relief mattress topper uses 5cm of memory foam to adapt to your body's unique contours. It cradles pressure points like the shoulders, hips and knees, promoting better spinal alignment and reducing tossing and turning. The hypoallergenic properties also make it a good choice for those with sensitivities.
- Pros:
- Provides targeted support and pressure relief.
- Contours to the body for personalised comfort.
- Helps to isolate motion, ideal for couples.
- Hypoallergenic material.
- 5cm thickness offers a significant comfort upgrade without being overly deep.
- Who is it for? Side sleepers, individuals experiencing back or joint discomfort or anyone seeking the signature body-hugging support that memory foam provides.

Frequently Asked Questions
What is the difference between a mattress topper and a mattress protector? A mattress topper is primarily designed to change the feel of your mattress—usually by adding a layer of comfort, softness or support. A mattress protector, on the other hand, is a thinner layer designed to shield your mattress from spills, stains, dust mites and allergens, with its main goal being hygiene and preservation.
How thick should a mattress topper be? This depends on your goal. A topper of 2-4cm will add a subtle layer of softness. For a more noticeable transformation, such as significant pressure relief or adding a plush, pillow-top feel to a firm mattress, a thick mattress topper of 5-8cm is generally more effective.
Can a mattress topper make a firm mattress softer? Yes, absolutely. This is one of the most common reasons people buy a topper. A quilted mattress topper with a generous microfibre or hollowfibre fill, like the NightComfort 800GSM model, is specifically designed to add a deep layer of softness to a firm sleeping surface. A memory foam topper can also soften the feel by allowing you to sink in slightly and cushioning your pressure points.
