Hexagon Puff Seat Cushion – Free Crochet Pattern
There is something wonderfully satisfying about crocheting something that is both beautiful and practical. A hexagon puff seat cushion sits right at that intersection — it brings geometric elegance to any chair, adds a soft layer of comfort underfoot or under you, and uses one of the most beloved stitch techniques in modern crochet. Whether you are a seasoned crocheter looking for a weekend project or an intermediate maker ready to level up your skills, this free crochet pattern will walk you through every step of creating your own hexagon puff seat cushion from start to finish.
Before we dive into the pattern itself, let’s talk about what makes this cushion so special and why hexagons have become such a staple shape in the crochet world.
Why Hexagons?
Hexagons have a natural tessellating quality — they fit together without gaps, which makes them endlessly versatile in crochet design. When you combine the hexagon shape with the puff stitch, you get something that has real depth and dimension. The puff stitch creates clusters of loops that sit raised from the fabric, giving the cushion a soft, cloud-like texture that is perfect for adding cushioning to a wooden chair, a bench seat, or even the floor.
Hexagonal shapes also lend themselves beautifully to colorwork. You can make each hexagon a different color and sew them together for a scrappy, boho look, or stick to a monochromatic palette for something more refined and modern. The pattern below is written for a single large hexagon, but notes are included if you want to piece together smaller ones instead.
Materials You Will Need
Getting the right materials makes a huge difference in how your finished cushion looks and feels. Here is everything you need to gather before you begin.
Yarn: Choose a medium weight (Category 4) yarn in a cotton or cotton-blend fiber. Cotton is the ideal choice for a seat cushion because it holds its shape well, is easy to wash, and has a subtle sheen that makes the puff stitches pop. You will need approximately 400 to 500 yards for a cushion that measures around 14 to 16 inches across. If you are making multiple hexagons to join, plan for about 80 to 100 yards per hexagon depending on size.
Hook: A US size J/10 (6.0 mm) crochet hook is recommended. You can go up to a K/10.5 (6.5 mm) if your tension tends to run tight. The goal is a firm but not stiff fabric — firm enough to keep its shape, soft enough to actually cushion.
Notions: A tapestry needle for weaving in ends and joining pieces if applicable, stitch markers to mark rounds, and scissors.
Optional: A thin foam insert cut to your hexagon shape, or polyfill stuffing to give the cushion extra loft. You can also sew a simple fabric backing onto the cushion to give it a more finished, professional look on the underside.
Gauge
Gauge is especially important for a functional item like a cushion. Too loose and the cushion will be floppy; too tight and it will be stiff and uncomfortable.
For this pattern, aim for approximately 12 stitches and 8 rows in a 4-inch square using the puff stitch and a size J hook. Because puff stitches are inherently three-dimensional, your gauge swatch will naturally be thicker than a plain single crochet swatch — that is exactly what you want.
Stitch Glossary
If you are unfamiliar with any of these stitches, take a few minutes to practice them before starting the main pattern. It will save you a lot of frustration.
Magic Ring (MR): Create an adjustable loop to begin crocheting in the round. This eliminates the visible hole that sometimes appears at the center of round projects.
Chain (ch): The foundation of most crochet projects. Pull up a loop and draw it through the loop on your hook.
Slip Stitch (sl st): Insert hook, yarn over, pull through both loops on hook. Used to join rounds and move yarn without adding height.
Single Crochet (sc): Insert hook, yarn over, pull up a loop, yarn over again, draw through both loops.
Double Crochet (dc): Yarn over, insert hook, pull up a loop, yarn over and draw through two loops twice.
Puff Stitch (ps): Yarn over, insert hook into the stitch, yarn over and pull up a loop to about half an inch tall. Repeat this — yarn over, insert, yarn over, pull up a loop — four more times into the same stitch (you should have 11 loops on your hook). Yarn over and draw through all 11 loops at once. Chain one to close the puff. This is the star of the whole pattern, so practice it a few times before starting.
Pattern Notes
Rounds are worked in joined rounds unless otherwise noted. At the end of each round, join with a slip stitch to the first stitch indicated, then chain up to begin the next round.
The cushion is worked from the center outward in a hexagonal shape, with puff stitches placed strategically to create the raised texture across the surface.
If you are using multiple colors, you can change colors at any slip stitch join between rounds. Simply drop your current color, pick up the new color, and continue with the join.
All chain spaces count as stitches unless noted otherwise.
The Pattern
Round 1: Begin with a magic ring. Chain 3 (counts as first dc), work 2 dc into the ring, ch 2, [3 dc into ring, ch 2] five times. Join with sl st to top of ch-3. Pull the magic ring closed. — 6 groups of 3 dc, 6 ch-2 corner spaces.
Round 2: Sl st into the first ch-2 space. Ch 3 (counts as dc), 2 dc in same space, ch 2, 3 dc in same space, [3 dc in next ch-2 space, ch 2, 3 dc in same space] five times. Join with sl st to top of ch-3. — 12 groups of 3 dc, 6 ch-2 corner spaces.
Round 3: Sl st to corner ch-2 space. Ch 1, work a puff stitch in the corner space, ch 1, puff stitch in same space, ch 1. Skip the next group of dc. [Work 2 puff stitches with ch 1 between in next corner ch-2 space, ch 1] five times around. Join with sl st to first puff stitch. — 12 puff stitches, 6 ch-2 corners established.
Round 4: Sl st into the first ch-1 space. Ch 3, 2 dc in same space, dc in next ch-1 space, [3 dc in ch-1 corner space, ch 2, 3 dc in same corner space, dc in next ch-1 space] five times. Join with sl st to top of ch-3.
Round 5: Sl st to corner space. Ch 1, puff st in corner, ch 1, puff st in same corner, ch 1. Work a puff stitch in each dc along the side, placing a ch 1 between each puff. At each corner, work 2 puff stitches with ch 1 between in the corner space. Continue around all six sides. Join.
Rounds 6–10: Repeat the pattern of alternating dc rounds and puff stitch rounds. Each dc round will add one more dc along each side between corners, and each puff round will add one more puff stitch along each side. The hexagon grows by one stitch per side per full sequence.
By the end of Round 10, your hexagon should measure approximately 12 to 14 inches across from flat edge to flat edge. For a larger cushion closer to 16 inches, work two additional rounds (one dc, one puff).
Final Round: Work a single crochet border all the way around the hexagon, placing 3 single crochets into each corner ch-2 space to keep the corners neat and defined. This border tidies everything up and gives you a clean edge for finishing or joining. Fasten off and weave in all ends.
Making a Stuffed Cushion
If you want a cushion with real loft and padding, you have two good options.
The first option is to make two identical hexagons and sew them together with a whip stitch around the edges, leaving a gap to stuff. Use polyfill or repurposed fabric scraps to fill the cushion to your desired firmness, then seam closed. This method gives you a fully crocheted cushion on both sides.
The second option is to crochet just one hexagon and sew a fabric backing to the wrong side. Cut a piece of durable cotton or canvas fabric slightly larger than your hexagon, fold the edges under, and hand stitch it in place around the perimeter. You can sew an envelope-style opening into the backing to allow for adding and removing a foam or fiber insert, which makes washing much easier.
For a floor cushion or meditation cushion, a 2-inch foam insert works beautifully and gives the finished piece a very professional look.
Joining Multiple Hexagons
One of the most popular ways to make this cushion is to crochet several smaller hexagons — each about 5 to 6 inches across — and join them into the final shape. This is a wonderful stash-busting project, since you can use different colors and textures from your yarn collection.
To make smaller hexagons, simply stop after Round 4 or Round 6 instead of continuing to Round 10. Each small hexagon should have a clean sc border worked around it before joining.
For the join, you can use the flat slip stitch join (worked with right sides facing each other), the join-as-you-go method (joining each new hexagon to the previous one as you work the final round), or a simple whip stitch with matching yarn using your tapestry needle. Each method gives a slightly different look, so choose the one that best suits the aesthetic you are going for.
A classic arrangement for a seat cushion is a flower formation — one hexagon in the center surrounded by six hexagons around it. This creates a larger, rounder shape that works well for round stools or chairs.
Color Ideas and Inspiration
The color palette you choose will completely transform the personality of this cushion. Here are some ideas to get you thinking.
A single-color cushion in a natural cream or warm oatmeal cotton has a timeless, Scandinavian feel that works with almost any interior. The texture of the puff stitches stands out beautifully in solid colors because there is nothing to distract from the dimensional stitch pattern.
For a boho or maximalist look, choose a gradient yarn or a rainbow sequence of solid colors across the rounds. Start with a deep jewel tone at the center — a rich teal or burgundy — and work outward through lighter shades, ending with a soft neutral border.
Earthy terracottas, warm sages, and dusty pinks make for a very on-trend combination if you are decorating with modern farmhouse or cottagecore aesthetics in mind. These colors also look wonderful together when used in separate hexagons that are then joined.
If you are making this cushion for a child’s room, consider bright primaries — a sunny yellow, a sky blue, a cheerful red — each used for a different hexagon in the joined version.
Care Instructions
Cotton yarn is generally very easy to care for, which makes it ideal for something like a seat cushion that will get regular use and need occasional washing.
Machine wash the finished cushion on a gentle or delicate cycle in cool water. Reshape the cushion while it is still damp and lay it flat to dry — never put it in the dryer if you want to preserve the shape and texture of the puff stitches. Heat can cause cotton to shrink and may distort all the careful work you put into those raised clusters.
If your cushion has a fabric backing, check whether the backing fabric is also machine washable before tossing it in. Spot cleaning is always an option for small spills if a full wash is not practical.
Finishing Tips for a Professional Look
The difference between a cushion that looks handmade in the best possible way and one that looks unfinished often comes down to the finishing work. A few simple tips will make yours look polished and professional.
Weave in your ends with extra care. Thread each tail onto your tapestry needle and weave it in and out through several stitches in different directions, then trim close. This prevents ends from working loose over time.
Block your hexagon before finishing or joining. Wet blocking — soaking the piece in cool water, pressing out the excess moisture in a towel, and then pinning to your final measurements on a foam mat to dry — is the single best thing you can do to even out your tension and make those hexagon edges perfectly straight. Puff stitches relax beautifully with blocking and the cushion will look much more intentional.
If you are adding a fabric backing, take the time to press the fabric edges neatly before sewing. Even a simple backstitch done by hand looks far more refined when the fabric has been pressed flat and the corners are mitered.
Skill Level and Time Estimate
This pattern is rated intermediate. If you are comfortable with working in the round, the puff stitch, and basic shaping, you will find this project very manageable. The hexagonal shaping is intuitive once you understand how corners are worked, and the puff stitch, while a little fiddly at first, becomes rhythmic very quickly.
For the single-hexagon version, most crocheters complete the project in four to six hours of focused work. That makes this a wonderful weekend project, or something you can chip away at over several evenings. The joined hexagon version takes longer depending on how many small hexagons you plan to include, but each small hexagon only takes about thirty to forty-five minutes, so you can work on them in small sessions and assemble when you have enough.
A Note on Yarn Substitutions
If cotton is not available to you, a cotton-acrylic blend will also work very well and may be easier to find in certain regions or color ranges. Pure acrylic will give you a softer, slightly more elastic result but may not hold its shape as crisply over time with regular use. Wool is not recommended for a seat cushion unless it is superwash treated, since untreated wool can felt if washed incorrectly.
Always swatch with any substituted yarn before beginning, since fiber content and brand can significantly affect both gauge and the look of the puff stitch.
Final Thoughts
A hexagon puff seat cushion is one of those projects that rewards you on multiple levels. It is satisfying to make, genuinely useful once finished, and beautiful enough to be a real decorative accent in your home. Whether you place it on a kitchen chair, a garden bench, a stool by your vanity, or the floor of a cozy reading nook, it brings handmade warmth to everyday life in the best possible way.
The free pattern above gives you everything you need to get started, but do not be afraid to make it your own. Change the colors, adjust the size, experiment with the yarn weight, or add an embroidered detail to the center hexagon. Crochet is at its best when it is personal, and this pattern has plenty of room for your own creative voice to come through.
Happy crocheting — and enjoy every puff stitch along the way.
