Minus the quilted bamboo rayon upper layer that the Panda Hybrid Bamboo offers, the Panda Memory Foam pillow doesn't feel as luxurious, but it still offers good quality compared to most similar firm memory foam pillows we've tested. Its textured cover, which can be unzipped and washed at 40°c is a nice touch. As is the embroidered Panda logo – although unfortunately, we did find this showed through pale coloured pillowcases, so we tended to flip the pillow to the reverse to hide it. Overheating is one of the most common reasons for disrupted sleep or night-time waking. If you regularly flip your pillow over at night looking for the cooler side, it’s likely you need a ‘cooler’ more breathable option. The fluffy feel of the Boll & Branch Down Chamber Pillow appealed to testers who enjoy molding and cuddling their pillow at night. It also retains minimal heat, so you won’t need to worry about excessive heat retention. The only testers this pillow didn't impress were those who prefer a firmer sleep surface – it is quite soft – and those who prefer to opt for more breathable natural materials over synthetics. You may wash the pillow in cold water on a gentle cycle and tumble dry on a low setting. Note that it may take several cycles to dry your pillow completely.

Super Standard:Super Standard pillows measure 20 inches wide by 28 inches long. Like standard pillows, they are usually used one per twin or full bed, and two per larger bed. Super Standard pillows provide 2 more inches of length for sleepers who need it due to head size, body weight, or propensity to move during the night. Tempur is the brand widely accredited with creating the very first memory foam as-we-know-it after it adapted 'viscoelastic'–a material invented by NASA for use as cushioning in its spacecraft – for use in mattresses. It remains the only sleep brand to hold NASA's Certified Space Technology® license. The Boll & Branch Down Chamber Pillow is composed of three chambers. The soft pillow contains down in all three chambers to provide a plush, lofty feel. The medium and firm pillows contain feathers and down in the inner chambers, surrounded by a layer of down. This design enhances support in the core while keeping the surface soft and fluffy. The shell is composed of 100% cotton.Box pillows have walled sides and are increasingly popular. They can come with a variety of fillings including memory foam and synthetic fibres. Thanks to its adjustable fill (a genius concept) multiple testers found this Simba option to be the best pillow for side sleepers overall.

The Panda Memory Foam pillow is higher than the Panda Hybrid Bamboo pillow and a good degree firmer, but in our tests, it proved very popular with our side sleeping testers with wider shoulders who appreciated the extra loft. Body Pillow:Body pillow dimensions vary, though 48 or 54 inches wide by 20 inches long are common sizes. Body pillows are meant to be hugged. Side sleepers and pregnant women tend to most enjoy them. A boxwall or memory foam pillow can be a good bet here as they both provide a more structured pillow that offers height but prevents your head from sinking too much. Or, a pillow with adjustable fill – like the two on our shortlist – can help you to create just the right height pillow for your body frame.We also recommend the pillow for hot sleepers, thanks to the naturally breathable materials. Our heat guns detected very little heat buildup on the pillow’s surface. The fiberfill also made the pillow quite moldable during our tests, which is great if you prefer to snuggle your pillow at night. The pillow’s core consists of solid Talalay latex. This material is more resilient than Dunlop latex, making it bouncier and less dense. The latex is ventilated with small holes allowing air to circulate throughout the interior. A Tencel cover encases the core. You can remove and machine wash the cover whenever it needs to be cleaned. The pillow is available in queen and king sizes, as well as lofts of 4 or 5 inches.
