Hexagon Puff Seat Cushion – Free Crochet Pattern

There is something deeply satisfying about sitting down on a cushion you made yourself. When that cushion happens to be built from a cluster of plump, textured hexagons stitched together into something both beautiful and functional, the satisfaction doubles. This free crochet pattern for a hexagon puff seat cushion is exactly that kind of project — one that rewards you with a finished piece you will want to show off and sit on every single day.

Whether you are new to crochet or have been crocheting for years, this pattern is designed to be approachable without being boring. The puff stitch adds dimension and softness, the hexagon shape gives you a modern geometric look, and the final assembly comes together in a way that feels genuinely rewarding. By the time you finish, you will have a cushion sturdy enough for daily use and stylish enough to anchor a room.

Let’s get into everything you need to know.

Why a Hexagon Puff Seat Cushion?

Seat cushions are one of those crochet projects that sit at a perfect intersection of practical and decorative. They are useful enough to justify the time it takes to make them, and decorative enough that they genuinely elevate a space. A wooden dining chair becomes more inviting. A meditation corner gets a handmade focal point. A front porch rocker suddenly looks like it belongs in a magazine.

The hexagon shape specifically is having a well-deserved moment in the crochet world. Hexagons tile together without gaps, which means you can build a surface of almost any size simply by adding more units. They are also visually dynamic — the angles create movement in a way that squares and circles do not. Combined with the puff stitch, which creates raised, cloud-like clusters of yarn, the finished cushion has a texture that people cannot resist touching.

Practically speaking, a seat cushion in the round (or in hexagonal panels) also gives you a great opportunity to practice join-as-you-go techniques, color blending, and stuffing methods. It is the kind of project where you will come away a noticeably better crocheter than when you started.

Materials You Will Need

Before you cast on your first stitch, gather everything you need so the process flows smoothly. Here is a complete list of materials for a finished cushion approximately 14 to 16 inches across, which fits most standard chair seats.

Yarn: Medium weight yarn (size 4) works beautifully for this project. You will need approximately 400 to 500 yards for a single-colored cushion, or you can divide that across two or three complementary colors for a more striking effect. Cotton yarn holds its shape well and is easy to wipe clean, making it a smart choice for a seat cushion. Wool blends add warmth and spring. Acrylic is budget-friendly and widely available. Any of these will work — choose based on where the cushion will live and how much use it will get.

Hook: A size 5.0mm (US H/8) crochet hook is recommended for medium weight yarn, but always check your tension. If your hexagons are pulling tight and stiff, go up a hook size. If they are loose and floppy, go down.

Stitch marker: You will want at least one to mark round beginnings as you work each hexagon.

Yarn needle: For weaving in ends and joining hexagons.

Polyfill stuffing or foam insert: You will need enough to give the cushion a generous puff. For a firmer cushion, a cut foam insert works wonderfully. For a softer, more cloud-like feel, polyfill is the way to go. Many crafters use a combination — a thin foam layer wrapped in polyfill.

Scissors: A sharp pair makes clean cuts and helps with weaving in ends.

Optional: Buttons, ties, or non-slip backing material if you want to anchor the cushion to a chair.

Understanding the Puff Stitch

If the puff stitch is new to you, a few minutes of practice before starting the main project will make everything click. The puff stitch is worked by drawing up multiple loops in the same stitch before pulling through them all at once. The result is a rounded, raised cluster that looks almost like a small pillow on the surface of your work.

Here is how to work a standard puff stitch for this pattern:

Insert your hook into the designated stitch or space. Yarn over and pull up a loop to the height of a double crochet (you should have three loops on your hook). Without pulling through, yarn over and insert your hook into the same stitch again. Yarn over and pull up another loop to the same height (five loops on hook). Repeat this process two more times so you have nine loops on your hook. Yarn over and pull through all nine loops. Chain one to close and secure the puff.

That chain one at the end is important — it locks the puff in place and keeps it from collapsing. Practice this on a small swatch until it feels comfortable. Within a few repetitions, your hands will find the rhythm and the puffs will start popping up beautifully and consistently.

Pattern Notes and Abbreviations

Before the pattern begins, here are the abbreviations used throughout:

ch — chain
sl st — slip stitch
sc — single crochet
dc — double crochet
ps — puff stitch (as described above)
sp — space
rep — repeat
rnd — round
beg — beginning

The pattern is written for US crochet terminology. If you are accustomed to UK terms, remember that a US single crochet equals a UK double crochet, and a US double crochet equals a UK treble crochet.

Each hexagon is worked in continuous rounds, joining at the end of each round with a slip stitch. You will make a total of seven hexagons — one center hexagon surrounded by six outer hexagons — to form the cushion top. The cushion bottom is worked as a single flat hexagon in the same dimensions, then the two are joined with stuffing in between.

The Hexagon Puff Pattern

Magic Ring Start

All hexagons begin with a magic ring (also called a magic circle or adjustable ring). If you are unfamiliar with this technique, you can substitute by chaining four and joining with a slip stitch to form a small ring.

Round 1:
Ch 3 (counts as first dc), work 11 dc into the ring, join with sl st to top of beginning ch-3. Pull the magic ring tail to close. (12 dc)

Round 2:
Ch 1, sc in same st. ps in next st, sc in next st. Rep from to five more times. On the final repeat, ps in the last st, join with sl st to first sc. (6 sc, 6 ps)

Round 3:
Sl st into the top of the first ps. Ch 3 (counts as dc), 2 dc in same ps top. Ch 1. 3 dc in top of next ps, ch 1. Rep from to four more times. 3 dc in last ps. Ch 1, join with sl st to top of beg ch-3. (6 groups of 3 dc, 6 ch-1 sp)

Round 4:
Sl st into next 2 sts to reach the ch-1 sp. Ch 1, sc in same sp. Ch 2. ps in next ch-1 sp, ch 2, sc in same sp. Ch 2. Rep from to five more times, ending with a final ch 2, join with sl st to first sc. (6 ps, 12 ch-2 sp)

Round 5:
Ch 3, dc in same st. 2 dc in next ch-2 sp. In top of next ps: (2 dc, ch 2, 2 dc) for the hexagon corner. 2 dc in next ch-2 sp. 2 dc in next sc. 2 dc in next ch-2 sp. Rep from to five more times, working the last corner in the final ps and joining with sl st to top of beg ch-3. (6 corners with ch-2 sp, dc groups along each side)

Round 6:
Ch 1, sc evenly around, working (sc, ch 2, sc) in each corner ch-2 sp. Join with sl st to beg ch-1. Fasten off and weave in ends.

This completes one hexagon. Make seven using this pattern for the cushion top. For a solid color cushion, use the same yarn throughout. For a multicolor cushion, switch colors between rounds or use a different color for each hexagon.

Assembling the Cushion Top

Once you have seven hexagons, lay them out flat to plan your arrangement. Place one hexagon in the center and arrange the remaining six around it, rotating them so their edges align neatly. This is a great time to decide if you want any color arrangement to follow a specific order.

Join the hexagons using the flat slip stitch join or the join-as-you-go method. The flat slip stitch join is the most beginner-friendly: hold two hexagons with wrong sides together and use your yarn needle to whip stitch or sl st through the back loops of corresponding stitches along the shared edge. Work slowly and keep your tension even. The join should lie flat without puckering.

Work from the center outward, joining each outer hexagon to the center hexagon first, then joining neighboring outer hexagons to each other along their shared edges. As the last few hexagons are added, the assembly will start to feel three-dimensional and the full shape will emerge.

Making the Cushion Bottom

The cushion bottom is a single large hexagon worked in the same yarn. You can follow the same hexagon pattern and simply continue adding rounds until it matches the diameter of the joined cushion top (approximately the same size as all seven hexagons assembled). This usually means working two to four additional rounds beyond Round 6, depending on your tension.

Alternatively, you can work the bottom as a simple flat hexagonal shape using double crochets, without the puff stitch texture, since the bottom will not be visible. Either approach works well.

Stuffing and Closing the Cushion

Place the cushion top face-down and position the bottom piece face-up on top of it, so the wrong sides of both pieces are facing each other and the right sides face outward. Align the edges as evenly as possible.

Using your yarn needle and a length of yarn, begin joining the two pieces together around the perimeter using the same flat join method used for the hexagons. Work around approximately five of the six sides, then pause to stuff the cushion.

Insert your polyfill or foam insert through the opening. Add stuffing generously — seat cushions compress with use, so a firmly stuffed cushion will feel perfect within a few days of regular sitting. If you want a flatter, firmer cushion, use a pre-cut foam insert sized to match your hexagon assembly. If you prefer a softer feel, pack in polyfill until the cushion has a gentle dome shape.

Once stuffed to your liking, close the remaining side with your yarn needle, fasten off securely, and weave in all remaining ends.

Finishing Touches and Customization

A finished cushion can be left as is, or you can add a few personal details to make it truly your own.

If the cushion will live on a chair that might shift or slide, sew a few small non-slip pads to the bottom, or cut a piece of non-slip rug liner to size and attach it with a few stitches at the corners. This keeps the cushion firmly in place even on smooth wooden or metal chairs.

For a tied cushion that attaches to a chair back, cut four lengths of matching yarn or ribbon (each about 18 inches long) and secure them in pairs at the back corners of the cushion. These tie around the chair’s back posts and keep everything in position.

You can also embellish the top of the cushion with crocheted flowers, buttons pressed into the puff centers, or surface slip stitch lines that highlight the hexagon joins. These details are purely decorative but add a lovely artisan quality to the finished piece.

Color Palette Ideas

Color is where this project can really shine. A few combinations that work particularly well for hexagon puff seat cushions:

A tonal palette of cream, warm beige, and soft camel creates a neutral cushion that pairs with almost any furniture. It reads as modern and understated, with enough variation to keep it interesting.

Jewel tones — a deep teal center hexagon surrounded by six hexagons in mustard, rust, and plum — make a bold statement that works well in a boho or eclectic space.

For something softer, dusty sage paired with off-white and blush creates a palette that feels calm and cottage-like. This combination is especially lovely for a bedroom reading chair or a nursery glider.

A single saturated color like terracotta or cobalt blue is striking in its simplicity and tends to photograph beautifully, which matters if you plan to share your work online.

Care Instructions for Your Finished Cushion

The care routine for your cushion depends largely on the yarn you chose. Cotton and most acrylics can be machine washed on a gentle cycle in cool water and laid flat to dry. Wool blends should be hand washed in cool water with a wool-safe detergent and reshaped while wet before drying flat. Always check the care label on your specific yarn.

If your cushion uses polyfill stuffing, it can typically handle a gentle wash cycle, though the stuffing may shift slightly and need to be redistributed once dry. Foam inserts should be removed before washing if possible, or spot-cleaned in place.

Giving your cushion an occasional fluff — just pressing it back into shape with your hands — keeps the puff stitch texture looking its best and extends the life of the stuffing.

Tips for Success

A few things that will make this project significantly easier:

Blocking your hexagons before assembly makes a noticeable difference. Lightly spray each finished hexagon with water, pin it into shape on a foam mat, and allow it to dry completely. This evens out any tension inconsistencies and gives each hexagon crisp, defined edges that join much more neatly.

Keep your puff stitches consistent by always drawing your loops up to the same height. A loose puff and a tight puff side by side will show, so take your time in the early rounds until the motion feels natural.

Weave in ends as you go rather than leaving them all for the end. With seven hexagons, the end-weaving can feel tedious if saved for last. Doing it after each hexagon keeps the project feeling manageable.

If your joined cushion top has slight gaps at the hexagon intersections, use a yarn needle to work a few small stitches that pull the edges together without distorting the fabric. A tiny bit of strategic seaming can make a join look seamless.

Final Thoughts

A hexagon puff seat cushion is the kind of project that gives back in multiple ways. The process is engaging and rhythmic — the kind of crocheting that quiets a busy mind. The assembly is a satisfying puzzle. And the finished object is genuinely beautiful and useful, the sort of thing that makes a room feel cared for and personal.

This free pattern is yours to use, adapt, and make your own. Change the colors, adjust the size, experiment with yarn weights, or try working the hexagons in a tunisian crochet variation if you want a denser fabric. The bones of the pattern are flexible enough to support all kinds of creative choices.

If you make this cushion, take a moment to look at what you built before you sit on it. Seven hexagons, hundreds of puff stitches, and countless small decisions about color and texture, assembled into something that will outlast the season and probably outlast several seasons after that. That is what handmade means — made with intention, made to last, and made by you.

Happy crocheting.
