DIY Upholstered Waterfall Bench

I’ve been wanting to make an upholstered waterfall bench for years! But just the idea of this project has really intimidated me, due to my lack of upholstery skills. After a couple of years upholstering miniature furniture (no joke!), I’ve built up the confidence to finally try my hand at upholstering a life-size piece of furniture that I actually built myself … out of material that isn’t balsa wood and super glue!

I’ve gotta say—this project was not as difficult as I had built it up to be in my mind. Whew! Such a relief at how straightforward it was. It’s even a project you can do in one day! However, I also must say, I didn’t do it perfectly, which is a bit of a bummer for a detail-oriented person such as myself. But I think it turned out pretty well for my first try at this type of upholstery. I certainly learned a few things along the way that will help me next time, and help you your first time! Read on to learn how to make your own upholstered waterfall bench.

upholstered waterfall bench DIYMaterials:
-2 pieces of 2x8x7 lumber (I used poplar) to make a 55″ long bench. Use shorter pieces of wood for a shorter bench.
-3″ construction screws (I used 12 of these)
Wood glue
-2 1/2 yards of heavyweight upholstery fabric
-2 1/3 yards of 16″ wide 2″ thick foam (this is a standard piece of foam that can be trimmed to fit)
3/8″ T50 staples
-Chipboard tack strip
-Metal tack strip
-Furniture glides (I used 6 of this type)

Tools:
Chop saw
-2 Long clamps (able to span at least 15″)
Carpenter’s square
Power Drill
-Staple gun (this electric one is so handy and easy to use!)
Electric carving knife
-Rubber mallet

Tool Workarounds

Don’t have a chop saw? Don’t worry! You can still complete this project without one. Most lumber yards or hardware stores will make cuts for you, and sometimes without a charge. Likewise, if you don’t have long clamps, you can do what I used to do before I invested in clamps—simply use duct tape stretched tightly to hold your wood while the glue dries.

Step One: To make a 55″ long bench (like mine), you will need each of your two 2×8 boards cut into the following lengths: two 13.5″ long pieces; one 55″ long piece. That will give you a total of four 13.5″ long pieces and two 55″ long pieces of wood.

Step Two: Right now your pieces of wood are only 7.5″ wide. You will want to edge glue the pieces together so they become 14.5″ wide. Squeeze wood glue onto the edge of one 13.5″ board and connect it to another piece of the same size. Clamp them together for at least 10 minutes, allowing the wood to dry. It’s a good idea to wipe away any seeping wood glue before it dries. Repeat this for another pair of 13.5″ pieces as well as the pair of 55″ pieces.

After this step is complete, you will have two 14.5″x13.5″ pieces of wood for the legs of your bench and one 14.5″x55″ piece of wood for the top of your bench.

Step Three: Apply wood glue to the top of your bench legs and attach them to the bench top. As you clamp the pieces together, make sure that the legs are perfectly square with the top. Use a carpenter’s square to verify this as you tighten the clamps.

Step Four: Make sure the legs are clamped for about 10 minutes before removing clamps. Next, drill pilot holes and countersink the holes so the screws will be recessed into the wood as they’re drilled into place. In the top right image, you can see that I have countersunk the top two holes.

You can drill the holes while the wood is clamped or after the clamps have been removed. But I do recommend screwing together the wood before the glue has completely dried.

Step Six: Lay out your foam across the top of the wood bench and trim the foam to fit the width and length of the bench. Use an electric carving knife along the edge of the bench to trim the foam. My parents only get out their carving knife when it’s Thanksgiving or when I’m doing an upholstery project!

upholstered waterfall bench DIYStep Seven: Cut a 30″ wide strip of your upholstery fabric to staple across the top of your bench. Begin by stapling it to the bottom of one leg as shown above left. Then stretch it super tight and staple to the other leg. I used a piece of quilt batting between the foam and fabric, because I happened to have extra quilt batting on hand. But I don’t think it’s necessary for this project as long as you’re using heavyweight fabric.

After securing each end, work your way around until all of the fabric is tightly stapled onto the underside of the bench. Use the weight of your body on the upside-down bench to squish the foam down, allowing for a tighter upholstery job. At the corners, try to make neat folds as the fabric wraps around the foam.

upholstered waterfall bench DIYStep Eight: Cut a 16″ wide strip of fabric for the underside of the bench. Laying the fabric face-down, staple the kraft upholstery tack strip right up to the edge of your bench. This will make a nice, crisp edge for the underside of the bench upholstery (as seen below left). Attach the middle section (not the legs) and stop. Complete the next step before doing the tack strips on the legs.

upholstered waterfall bench DIYStep Nine: Flip the fabric so that the nice side is now positioned up. Look how nice that edge is, thanks to the tack strip! This next part is the trickiest. You’ll need to take your metal (or spiked kraft strips, in my case) tacking strips and poke the spikes through your fabric that slightly overhands the edge of your bench, as shown above right. If you leave any slack in your fabric (as I accidentally did), then you’ll end up with wrinkles in the fabric.

upholstered waterfall bench DIYStep Ten: Flip the tack strip under and gently begin pounding along its length with a rubber mallet until all of the staples are punched into the wood bench.

Repeat steps 8-10 for the legs of the bench as well. When you get to the bottom of the legs, use another spiked tack strip to tuck under the raw edges of the fabric at the feet.

Step Eleven: Finish the feet of the bench with some plastic furniture gliders. I thought three for each side seemed to do the trick nicely.

Next time, I’ll be more careful in this step. But overall I think it looks pretty good for my first time doing a completely finished upholstery project!

upholstered waterfall bench DIYThis bench makes a great entryway seat, coffee table, or resting spot for the foot of a bed. And by resting spot, I mean resting spot for clothes that didn’t quite make it to the hamper, right?! If you don’t have space for a 55″ wide bench, simply use shorter boards for the middle, and save money on lumber! I think it would also be nice to make a set of two small, matching benches. What color would you choose for your fabric? – Mandi

  • Mandi –
    I love upholstery and I have done a lot of it, but I’ve never thought of upholstering a coffee table like this. What a great idea.
    One comment from my own experience: I have never used a tack strip, mostly because I couldn’t find them locally. I use a stapling strip on one side (as it appears you are doing in the photo) and blind stitch the other side by hand. You imagine it will be a huge job, but it goes fairly quickly and has a meditative quality to it. But the biggest advantage is that you can pull the fabric tight with each stitch, giving you a beautiful finish. Just a thought for the future. Thank you for the post.

    • That is such a helpful tidbit, thank you! I definitely would prefer doing a slip stitch here because I’m certain I’d be able to get the fabric tighter, and I wouldn’t have the expense of tack strips.

  • You guys all make DIYs look so easy! This pop of color is fun. I’m always so inspired by your creativity.

    • It’s hard to say, because I took lots of breaks to do life as I was making it. 🙂 But It took me about two hours to make the wood bench, and about an addition two hours to upholster it. But if your’e using these techniques for the first time ever, I’d add at least an hour or maybe two to the time, because you’ll want to really make sure you’re doing everything right before cutting and drilling. That kinda thing. 🙂
