A full-length body pillow is the simplest and most versatile body pillow design available. No curves, no hooks, no special shapes — just a long, straight pillow that runs the length of your body. Despite their simplicity, full-length body pillows remain the best-selling body pillow type because they adapt to virtually any sleeping position and support need. Here is how to choose the right one.
Standard Dimensions
Full-length body pillows in the UK typically measure 50 x 137 centimetres (20 x 54 inches). Some manufacturers offer compact versions at 50 x 120 cm for shorter adults or teenagers, and oversized versions at 50 x 150 cm for taller individuals. The pillow should reach at least from your chest to your knees when hugged in the side-sleeping position.
Width matters as well as length. Most body pillows are 20 to 25 cm wide when compressed by a sleeping body. Wider pillows (25+ cm) provide more surface area for hugging and more cushioning between the knees, but take up additional bed space. For couples sharing a standard double bed, a narrower body pillow preserves more room for both sleepers.

Fill Types
Polyester Fibre
The most common and affordable fill. Polyester fibre body pillows feel soft and plush, compressing easily under body weight. Good-quality siliconised polyester maintains its loft reasonably well over months. Budget polyester flattens quickly, especially in the knee section where concentrated leg weight compresses the fill fastest. Polyester-fill body pillows are fully machine-washable, which gives them a practical advantage over foam fills. See our polyester and microfibre pillow section for more on fibre qualities.
Shredded Memory Foam
Small pieces of memory foam packed inside the pillow shell. Shredded memory foam provides firmer, more structured support than polyester while still conforming to body contours. The pieces shift and rearrange under pressure, allowing the pillow to mould around your body. Adjustable versions with zip access let you add or remove fill to control firmness and loft, similar to adjustable bed pillows.
Microbeads
Tiny polystyrene beads (similar to bean bag filling but much finer) that flow and shift around your body. Microbead body pillows feel fluid and moulding, conforming almost instantly to any position. The beads provide moderate support — less firm than foam, less plush than fibre. Microbead pillows are lighter than foam or fibre alternatives and sleep cooler because the beads do not trap heat the way solid fills do.
Down Alternative
Premium microfibre engineered to mimic the softness of natural down. Down alternative body pillows feel luxuriously plush and cloud-like. The softness comes at the cost of support — down alternative compresses significantly under body weight and provides more cushioning than structural alignment. Best for sleepers who want comfort and cosiness rather than firm ergonomic support.
Latex
Shredded natural latex provides the most durable and resilient body pillow fill. Latex bounces back faster than any other fill material, maintaining its shape night after night for years. The natural breathability keeps the pillow cool, and latex is naturally hypoallergenic. The trade-off is higher cost and heavier weight.
How to Use a Full-Length Body Pillow
Side Sleeping
The classic body pillow position. Lie on your side and hug the pillow along your front. Your head rests on your standard bed pillow (or the top end of the body pillow), your top arm drapes over the body pillow, and the bottom section passes between your knees. The pillow supports your arm (preventing the top shoulder from rolling forward), fills the gap between your knees (aligning the hips), and gives your body something to lean against rather than twisting or curling.
Back Support
Place the body pillow behind your back while lying on your side. The pillow acts as a wall that prevents you from rolling onto your back during sleep. Useful for pregnant women past the first trimester, people with positional sleep apnoea, and anyone who needs to maintain a side-sleeping position.
Belly Support
Position the pillow in front of you and rest your belly on it. Pregnant women in the second and third trimesters find this particularly helpful. The pillow supports the weight of the growing bump, reducing the forward pull on the lower back. For more comprehensive pregnancy support, see our C-shaped and U-shaped body pillow options.
Elevation
Place the body pillow under your legs while lying on your back. Elevating the legs above heart level promotes blood circulation and reduces swelling in the feet and ankles. Useful for people with varicose veins, lymphoedema, or post-exercise leg fatigue.
Cover Options
Full-length body pillows use the most widely available body pillow case size. Standard 50 x 137 cm covers fit most full-length pillows without needing brand-specific shapes. Cotton, bamboo, jersey, and microfibre covers are all widely available. Buy at least two covers for rotation during weekly washing.
