Bolster Pillow Guide: Sizes, Covers, Inserts & Shopping
Ever wonder if that long, round pillow actually does anything? You’re not alone. Bolster pillows are often overlooked, but once you bring one into your space, you’ll wonder how you lived without it. From adding structure to your room to giving you unexpected back or neck support, these pillows do more than just look good.
Before you hit checkout, it's worth knowing what you’re really getting. Bolster pillows come in all shapes and materials—each affecting both comfort and style in different ways.

This guide covers the key things to look out for—sizes, covers, inserts, and the best places to buy them online—so you know exactly what works for your home and why.
Not All Bolster Pillows Are the Same Size
You’d be surprised how much size matters here. A small bolster might be just what your back needs on a reading chair, but drop that same one on a king-size bed and it’ll disappear. On the flip side, a long, oversized bolster can overwhelm a loveseat.
The typical pillow lengths and widths range from 6" x 12" to 9" x 32", yet custom-made options are available for specific endpoint requirements. The pillow length determines its suitable placement since slender, shorter ones fit well in corners and small seating areas, but larger versions fit best on beds and window benches.
What really counts is proportion. The right size adds structure and comfort without looking awkward or out of place.
Covers Make a Bigger Impact Than You Think
A good bolster pillow cover does more than dress up your pillow. It adds texture, protects the insert, and sets the tone for the whole room.
Some people go for leather to create a modern look, while others love velvet for a more luxurious feel. When searching for something easygoing with breathable properties, linen or cotton materials produce excellent results.
Hidden zippers and envelope closures aren’t just aesthetic—they’re practical. You’ll want to take that cover off eventually, whether it’s for washing or swapping out for the season.
Stick with neutrals if your space is already bold, or go the other way around—choose a punchy color or pattern if everything else is quiet. Either way, keep an eye on fabric quality. A beautiful cover that fades or unravels after a few washes won’t do you any favors long term.
What’s Inside Counts Just as Much
People often forget the bolster insert, but it’s what gives the bolster its shape and feel. If you’re using it to prop yourself up, don’t go too soft. If it’s more for looks, then plush and squishy is just fine.
You’ll find inserts filled with polyester, down, memory foam, or latex. Each one feels different. Well-defined structural support is available in polyester fabrics due to their shape-retention ability.
The down material offers better luxury than polyester, although not everyone appreciates its sinking feeling. Memory foam maintains high structural support that works best when using the pillow for back or neck support.
The fit matters too. If your insert is too small, the whole pillow will sag. Too big, and the cover might stretch awkwardly. Go for a bolster insert that’s just a bit longer than your cover—it fills it out nicely without looking overstuffed.
Where To Buy Bolster Pillow Matters More Than You Think
Anyone seeking bolster pillows can easily order an item from our store. You should investigate different options if you need a handmade product of uncommon fabric size.
You can find ready-to-go, stylish, and excellent-quality bolster pillows at both West Elm and Pottery Barn. Etsy presents an extensive selection of handmade clothing along with customized bolster pillows through its various vendor shops. You can pick the fabric, size, and even the type of insert.
Before you buy, read the fine print. Some listings don’t include the insert; others do. Make sure you know what you're getting—bolster pillow cover only, insert only, or a complete pillow. And don’t skip the reviews. That’s where you’ll find out whether that “linen” cover is actually polyester or if the pillow flattens after a week.
A Few Styling Ideas That Actually Work
There’s no rulebook here, but a few tricks can help. If you’re styling a bed, place a single long bolster across the front—clean, symmetrical, and doesn’t crowd the space. For a sofa, try a bolster at one end instead of a standard throw pillow. It adds contrast and draws the eye without screaming for attention.
In corners or on a bench, two smaller bolsters at each end can create balance without feeling too styled. Different fabric textures work equally well, so you can group velvet with linen or patterned with solid materials.
Mixing fabrics keeps things cozy without feeling too ‘done.
Wrapping It Up
Choosing a bolster pillow isn’t rocket science, but it’s worth putting a little thought into. The choice criteria extend beyond dimensions since fabric type and insert quality determine your perfect fit along with size and room placement.
The right pillow? It shows up for you—every day, every nap, every Netflix binge.
So take your time. Test different materials and evaluate how the item functions within your planned usage, then skip the ones that don’t pull their weight—you deserve better. Choosing the right pillow means you obtain something important that supports you day after day.
