Bolster pillows are round, cylinder-shaped pillows that sit against the arm of a sofa, the end of a chaise or the back of a daybed. Outdoors they need the same things as any pillow: fabric that handles sun and damp, and fill that dries. Many are sold as covers or inserts only, so check what the listing includes.

We compared outdoor bolsters on size, fabric, fill, cover design and care, and noted where a listing sells covers or inserts only. For flat rectangular pillows, see Best Outdoor Lumbar Pillows, or browse the Outdoor Cushions category.

How to Choose an Outdoor Bolster Pillow

Filled Pillow, Cover or Insert

Filled pillows are ready to use. Covers let you change colors or wash the fabric, and you add your own insert. When buying an insert, choose one sized to the cover the maker names, since inserts are often cut slightly larger to fill the ends.

Fabric

Solution-dyed acrylic such as Sunbrella holds color longest in sun. Spun polyester costs less but fades sooner. Check whether the cover zips off if you want to wash it.

Size

Bolster lengths and diameters vary between listings. Measure the seat or arm where it will sit, then compare that with each listing's stated size.

How We Evaluate Outdoor Bolster Pillows

For this guide we compared outdoor bolster pillows, covers and inserts on size, fabric, fill, cover design and care. We read each maker's specifications and left out bolsters sold only for indoor bedding. Most listings had no rating data in our product feed, so ratings did not decide the order. We did not handle these pillows ourselves, every figure comes from the maker's listing, and we never repeat a waterproof or fade claim as our own.

Variants of one listing count as a single product, and we would rather list a few strong picks than pad the list. Our full process is on the How We Review page.

FAQ

What is the difference between a bolster and a lumbar pillow?

A bolster is round and tube-shaped. A lumbar pillow is flat and rectangular. Both support the lower back or neck.

Can outdoor bolster pillows stay outside?

Most makers advise bringing pillows in or covering them in heavy rain and long periods of harsh weather.

What size insert do I need?

Use the size the cover maker recommends. Inserts are usually slightly larger than the cover so the ends look full.

Final Verdict

Cushion Source's Sunbrella bolster is our top pick for its fabric and US manufacture. RSH Decor offers a filled, US-made pair in polyester, and Austin Horn Classics sells machine-washable Sunbrella covers.

Sherry Kline adds a corded edge, while Prolinemax and Hofdeco sell inserts for covers you already own.
