Mattress Topper Guide
Whether you're looking to add extra comfort, support, or breathability without buying an expensive new mattress, a mattress topper is a simple yet effective way to enhance the overall feel of your bed. Toppers can help relieve pressure points and support temperature regulation—contributing to a more restful night’s sleep. With a range of fillings, including natural down, feathers, and advanced synthetics, at ProSleepClub you'll find a topper tailored to your specific comfort preferences.

Construction Features
Cassette Construction
Our mattress toppers are designed with internal compartments called "cassette boxes" to help keep the filling evenly distributed. This supports consistent comfort, airflow, and durability—reducing clumping and helping maintain loft and support across the surface.
High Thread Count 100% Cotton Casing
All our mattress toppers are encased in high thread count 100% cotton for a smooth, breathable feel that supports a comfortable night’s rest. Our 233 thread count cotton offers a soft, lightweight finish that balances durability with airflow, helping maintain a fresh sleep environment long-term.
Depth & Dual-Layer Construction
Our toppers are 7cm deep—offering balanced cushioning that can help ease pressure points and support healthy spinal alignment. This depth is ideal for those seeking deeper, more restorative rest.
Our Elite toppers feature a dual-layer design for enhanced comfort and support:
- Top Layer (2cm): Filled with a high proportion of down for a soft, breathable surface that gently cushions the body.
- Base Layer (5cm): Primarily filled with feather for a dependable supportive foundation for stable sleep positioning.
This combination delivers a luxurious balance of plushness and firmness—designed to support comfortable, uninterrupted rest so you can start your day feeling more refreshed.

Allergy Considerations
Natural Fillings – Down and Feather
Our Downafresh® certified down and feather mattress toppers are rigorously cleaned and processed to meet strict hygiene standards, minimising potential exposure to common allergens like dust and mites.
Plus, NOMITE® certification ensures that our tightly woven cotton casings act as an effective barrier against dust mites—offering a breathable, natural-filled option that many allergy-sensitive sleepers can enjoy with confidence.
Synthetic Fillings – Aerelle® Cool Night
For those with heightened sensitivities, our Aerelle® Cool Night filled mattress toppers provide an alternative that combines cooling comfort with hypoallergenic properties. These synthetic fibres are naturally resistant to dust mites and mould growth, unlike untreated natural materials, making them a practical option for sensitive sleepers—especially when paired with breathable, tightly woven cotton casings.
Breathable Cotton Casings
All our mattress toppers feature high thread count 100% cotton casings that are both breathable and tightly woven—supporting airflow while helping to reduce the infiltration of common allergens. These fabrics also aid in moisture regulation, contributing to a drier, fresher sleep surface.
Care & Maintenance
Our mattress toppers are designed for long-lasting comfort with minimal maintenance. Weekly care is simple—fluff gently, rotate regularly, and air out to keep it fresh and supportive. While mattress toppers can’t be machine washed, spot cleaning with warm, soapy water keeps them looking and feeling their best. For added protection, a washable mattress protector is a smart way to guard against wear, spills, and dust.

All our mattress toppers adhere to UK standard sizes. While we strive for precise measurements, the natural variation in handcrafted mattress toppers and the thickness of different fillings may result in slight size differences.
