10 Best Machine Washable Pillow 2025 in the UK

The Silentnight Deep Sleep Pillows 2 Pack offers a comfortable and versatile option for those seeking machine-washable pillows. Made from polyester and covered in microfibre, these pillows deliver a soft/medium level of support, making them suitable for a range of sleepers, including those who sleep on their front, back, or side.

One key strength is their hypoallergenic properties, which can help those with allergies have a more restful sleep. The pillows are designed to be fully machine washable, adding convenience to their maintenance. With a standard size of 70 x 45 cm and a thickness of 8 cm, they fit most pillowcases and beds comfortably.

Some users might find the medium support not firm enough if they prefer a very supportive pillow. Additionally, the breathability might not be as high as natural fiber options, which could be a consideration for those who sleep hot. Still, with a solid 4.3-star rating from over 28,000 reviews, these pillows are well-regarded and popular, making them a reliable choice for many.

The Silentnight Hotel Collection Pillows offer a luxurious hotel-like experience right in your own bedroom, thanks to their sumptuously soft embossed covers. Designed to cater to back and side sleepers, these pillows provide flexible support, allowing you to choose between a softer feel with one pillow or medium support by using both pillows. Made from polyester, the pillows maintain a decent level of comfort while being lightweight at just 500 grams each.

A major advantage of these pillows is their hypoallergenic properties, making them suitable for individuals with allergies or sensitive skin. The machine-washable feature is a convenient addition, ensuring that the pillows remain fresh and hygienic with regular cleaning. Their design includes temperature control, which adds to their comfort by helping to regulate your sleeping temperature.

On the downside, the pillows' polyester fill might not offer the durability or the loft retention over time compared to higher-end materials like memory foam or down. Those desiring very firm support might find these pillows lacking, as they are tailored more towards soft to medium support. Additionally, some users may not find the breathability as high as with more premium, natural materials.

Manufactured in the UK, the pillows are backed by a 2-year manufacturer’s guarantee, providing some peace of mind regarding their quality and longevity. With a solid customer rating and being a top seller in their category, these pillows are well-regarded by many users. They are a suitable choice for those seeking affordable, hypoallergenic, and machine-washable pillows with soft to medium support, though they may not satisfy those seeking firmer or more breathable options.

The Cosi Home® Luxury Memory Foam Pillows offer several appealing features for those seeking a machine-washable pillow. With memory foam filling and bamboo pillow covers, these pillows provide both firmness and comfort. The adjustable height feature is excellent for various sleeping positions, making it suitable for side, back, and stomach sleepers.

The cooling gel filling combined with breathable fabric helps keep hot sleepers comfortable, addressing breathability concerns effectively. Hypoallergenic properties are supported by the bamboo material and memory foam, which is known for resisting allergens. The removable bamboo cover adds convenience, as it can easily be machine-washed, maintaining hygiene without much hassle.

However, the pillows are relatively heavy at 3.6 kg, which might be cumbersome for some users to handle. The dimensions also suggest they are quite large, so ensure they fit your bed size. If you're a sleeper who values customizable support and cooling features, these pillows may suit your needs well, but consider the weight and size before purchasing.
