How to Build Ottoman Box with Storage: Step-by-Step for Beginners

How to Build Ottoman Box with Storage: Step-by-Step for Beginners - The Bed Store

How to build ottoman box with storage is one of the most rewarding DIY woodworking projects a beginner can take on. It combines practical storage with stylish furniture design, and the result is a piece you'll be proud to show off in any room of the house.

Building your own storage ottoman box lets you customise every detail, the size, the fabric, the lid mechanism, and the internal layout. Ready-made options like The Mayfair Luxe Blanket Box offer beautiful finished results, but going the DIY route means you get exactly what you want at a fraction of the cost. This guide walks you through the full process, from planning your build to sitting down on the finished product.

What Is an Ottoman Box with Storage?

An ottoman box with storage is a multi-functional piece of furniture that serves as a seat, footrest, and concealed storage unit all in one. The top lifts open, usually on hinges, to reveal a hollow interior where you can stash blankets, pillows, books, toys, or anything else that needs a home. It's a brilliant solution for rooms where space is tight.

You'll spot them most often at the foot of a bed, in living rooms, or in hallways. The structure typically consists of a wooden frame wrapped in foam padding and fabric upholstery. The result looks like a refined, intentional piece of furniture rather than a plain storage box with a lid.

What makes an ottoman box with storage so popular is its versatility. It can be styled to match almost any interior aesthetic, from clean Scandi minimalism to plush velvet luxury. If you've ever admired a piece like the Paneled Designer Ottoman Bench/Footstool and thought, "I could make something like that," you absolutely can.

The Basic Anatomy of a Storage Ottoman

Understanding the structure before you build helps everything make more sense:

  • The frame: A wooden box, usually MDF or plywood, that forms the structural base.

  • The lid: A flat wooden panel that sits on top, often padded and hinged.

  • The foam: High-density upholstery foam that adds comfort and shape.

  • The fabric: The outer covering that gives the piece its finished look.

  • The hardware: Hinges, lid stays, and optional legs.

Each component plays a role, and getting familiar with them now saves a lot of head-scratching later.

Why Build Your Own Instead of Buying One?

Buying a ready-made ottoman is perfectly fine; options like the 2025 Spanish Upholstery Style Ottoman Blanket Box are stunning straight out of the box. But building one yourself has some serious advantages that are hard to ignore.

Cost savings are the most obvious benefit. A quality ready-made storage ottoman can run anywhere from £150 to £300 or more. DIY materials for a comparable piece often come in well under £80, depending on your fabric choice and wood type. That's a meaningful saving, especially if you're furnishing an entire room.

Custom sizing is another big win. Standard retail ottomans come in fixed sizes. Your bedroom might need something longer, shorter, deeper, or narrower. When you build it yourself, it fits your space perfectly no compromises.

Then there's the personal satisfaction factor. There's something genuinely rewarding about sitting on a piece of furniture you built with your own hands. Every time a guest compliments it, you get to say, "I made that."

Finally, DIY lets you choose your exact materials,  the fabric colour, the foam density, the wood thickness, and the leg style. You're not locked into what's available in a showroom. The final product is yours, through and through.

Tools and Materials You'll Need

Before cutting a single piece of wood, it pays to get everything laid out and ready. Running to the hardware store mid-build breaks your momentum and wastes time. Here's a full breakdown of what you'll need.

Essential Woodworking Tools

You don't need a fully kitted workshop to pull this off. A modest set of tools does the job well:

Tool

Purpose

Circular saw or jigsaw

Cutting wood panels to size

Power drill

Pre-drilling holes and driving screws

Measuring tape

Accurate measurements throughout

Set square

Checking right angles

Clamps

Holding panels in place during assembly

Sandpaper (80, 120, 180 grit)

Smoothing surfaces before upholstery

Staple gun

Attaching foam and fabric to the frame

Scissors or fabric rotary cutter

Cutting upholstery fabric

Upholstery and Fabric Supplies

The upholstery side of the build is where your ottoman goes from a plain wooden box to a proper piece of furniture:

  • High-density foam (at least 40kg/m³) for the lid, and this is what makes the seat comfortable

  • Dacron or polyester wadding, a thin layer wrapped around the foam for a softer, rounder look

  • Upholstery fabric, velvet, linen, faux leather, or boucle all work well

  • Fabric glue or spray adhesive helps hold foam in place before stapling

  • Piping cord and fabric strips (optional), for a more tailored edge finish

Hardware and Fixings

Don't overlook the little bits. They're what hold everything together literally:

  • Wood screws (4cm and 5cm lengths)

  • Wood glue

  • Corner brackets or L-brackets for extra strength

  • Piano hinge or two standard butt hinges for the lid

  • Lid support stays (soft-close or standard)

  • Wooden or metal furniture legs (optional, but they elevate the look)

  • Sandable wood filler for hiding screw holes

Planning Your Ottoman Box Design

Rushing into cuts without a solid plan is the most common beginner mistake. Spend 30 minutes on design, and you'll save hours of frustration on the build. Think of it as your roadmap.

Choosing the Right Dimensions

The most popular dimensions for a bedroom-end ottoman are around 120cm wide × 45cm deep × 45cm tall. But these are just starting points. Measure your space and consider:

  • Width: Should it span most of the bed width, or is it a standalone accent piece?

  • Depth: Deep enough to store bulky items like duvets? Aim for at least 35cm internal depth.

  • Height: Standard seat height is 43–46cm. Factor in the foam and fabric thickness on top (usually adds 8–10cm).

Write your final dimensions down before you go anywhere near a saw.

Selecting Your Wood Type

For most DIY storage ottomans, you've got two practical choices:

MDF (Medium Density Fibreboard) is smooth, affordable, easy to cut, and takes fabric well. It's the go-to for most upholstered projects. The downside is that it's heavy and doesn't handle moisture brilliantly.

Plywood is lighter, stronger, and handles screws better than MDF. It's also more resistant to humidity. If your ottoman will live in a room that sees temperature changes (like a conservatory), plywood is the smarter pick.

For a standard bedroom ottoman, 18mm MDF or 18mm plywood is the right thickness.

Picking the Right Fabric

Your fabric does most of the visual heavy lifting. A few pointers:

  • Velvet gives a luxurious finish, but can be tricky to work with around corners and keep seams minimal.

  • Linen or cotton blends are forgiving, affordable, and very beginner-friendly.

  • Faux leather is durable, wipes clean, and great for living rooms or households with kids.

  • Boucle is trendy right now and adds a gorgeous texture, but it frays easily. Use a rotary cutter, not scissors.

Always buy 20% more fabric than you think you need. Mistakes happen, and running out of fabric mid-build is a nightmare.

Step-by-Step Guide to Building the Ottoman Box Frame

Here's where the real work starts. Take it one panel at a time, double-check every measurement, and don't rush.

Cutting the Wood Panels

You'll need six panels for a basic ottoman box:

  1. Front panel: full width × frame height

  2. Back panel: full width × frame height

  3. Two side panels: depth × frame height

  4. Base panel: sits inside the frame (width minus two panel thicknesses × depth minus two panel thicknesses)

  5. Lid panel: slightly smaller than the overall footprint to allow for fabric overlap

Cut carefully and label each panel with a pencil immediately after cutting. Mixed-up panels are a frustrating time-waster.

Pro tip: Ask your timber merchant to make the cuts for you. Many offer a cutting service that's either free or very cheap, and it saves you a lot of effort if you don't have a large workbench.

Assembling the Box Frame

With all panels cut and labelled, you can start putting the box together:

  1. Apply wood glue along the edge of the front panel.

  2. Butt the side panel against it and clamp firmly.

  3. Pre-drill holes every 20cm along the joint, then drive screws through.

  4. Repeat for all four sides.

  5. Drop the base panel in and attach it from below with screws through the frame sides.

  6. Check all four corners with your set square before the glue sets.

The set square step is one people skip, and they always regret it. A frame that's even slightly out of square will cause headaches every step of the way.

Sanding and Preparing the Surface

Once the frame is assembled and the glue is fully dry (give it at least 2 hours), go over the entire exterior with 80-grit sandpaper to knock back any rough edges, then move up to 120-grit for a smoother finish.

Fill any visible screw holes or gaps with sandable wood filler. Once dry, sand again with 180-grit. The smoother the surface, the better the fabric will look once it's applied. Lumps and bumps show through upholstery more than you'd expect.

How to Build the Hinged Lid

The lid is technically a separate build. It needs to be sturdy enough to bear body weight, well-padded for comfort, and hinged correctly so it opens and closes without drama.

Attaching the Lid to the Frame

The lid panel should be about 1cm smaller on all sides than the top opening of your box. This gives you room for the fabric wrap without the lid sitting proud of the frame edges.

Cut a piece of 18mm MDF or plywood to these dimensions. Sand all edges smooth and pay extra attention to the underside edges, which will be visible when the lid is open.

Attach the hinge along the back edge:

  • For a piano hinge, run it the full width of the back. This gives very even support.

  • For butt hinges, use two positioned roughly 15cm in from each end.

Mark and pre-drill all hinge holes before attaching them. Trying to drive screws into the edge of MDF without pre-drilling will split it.

Adding a Soft-Close Mechanism

Soft-close lid stays are a worthwhile addition, especially if children or elderly family members will be using the ottoman. These are spring-loaded hinged arms that attach to the inside of the box, one on each side, and prevent the lid from slamming down.

They're inexpensive (usually £5–£15 a pair) and installation takes about 10 minutes. Simply fix one end to the side panel of the box and the other to the underside of the lid. Test the action before upholstering; it's much easier to adjust before the fabric is in the way.

Upholstering Your Ottoman Box

This is the stage that transforms your project from a wooden box into a proper piece of furniture. It's easier than it looks, and the results are genuinely impressive.

Cutting and Attaching the Foam

For the lid, you'll need a piece of high-density foam cut to the exact top dimension of your lid panel. Most foam suppliers will cut to size for you, which is the easiest route. Aim for 5–8cm thickness for a comfortable seat.

Apply spray adhesive to both the top of the lid panel and the underside of the foam. Press firmly and allow 5 minutes to bond. Then wrap a thin layer of Dacron wadding around the foam and staple it to the underside of the lid. This softens the edges and rounds the silhouette slightly.

Wrapping with Fabric

Cut your fabric large enough to wrap around the sides of the lid and staple underneath — usually the lid dimensions plus 15cm on each side.

  1. Lay your fabric face down on a clean, flat surface.

  2. Place the foam-and-wadding lid face down on top of the fabric, centred.

  3. Pull the fabric taut on one long side and staple to the underside — work from the centre outward.

  4. Move to the opposite long side, pull firmly, and staple.

  5. Repeat for the two short sides.

  6. Fold corners neatly (like wrapping a present) and staple flat.

For the box body, cut panels of fabric to cover each side. Spray adhesive helps hold it in position while you staple. Work slowly around corners and keep the fabric grain straight throughout.

Adding Buttons or Tufting (Optional)

Tufting gives an ottoman that classic Chesterfield-inspired look. It adds time and requires a long upholstery needle and buttoning twine, but the result is genuinely striking. Mark button positions on the foam in a grid pattern, thread twine through from front to back, attach buttons, and pull tight. There are plenty of video tutorials available online that walk through this process visually, which can be helpful if it's your first time.

If you prefer a clean, modern finish like the Plain Top Style Ottoman Blanket Box, skip the tufting entirely and go for a smooth, plain wrapped lid instead.

Finishing Touches and Interior Storage Setup

You're in the home stretch now. A few final details make the difference between a project that looks good and one that looks professional.

Adding Legs or a Base

Legs lift the ottoman off the floor, improve air circulation, and add a refined, furniture-grade look. You've got options:

  • Screw-in wooden legs (tapered or straight): attach metal inserts to the base corners and screw legs in.

  • Block feet: small square blocks of wood, painted or stained, glued and screwed to the base corners.

  • Bun feet are rounded, a traditional style that works well with velvet fabric.

If you'd rather skip legs, a simple plinth (a flat frame the box sits inside) is another clean option.

Interior Lining Options

The inside of your ottoman doesn't need to be elaborate, but a bit of attention makes it feel complete:

  • Fabric lining: Cut panels of a contrasting or matching fabric and glue them to the interior walls. This protects stored items from rough wood edges.

  • Cedar lining strips: If you're storing woollen blankets or seasonal clothing, thin cedar strips stapled to the interior walls naturally deter moths.

  • Simply paint it: A coat of interior paint in a neutral colour is the quickest finish and looks perfectly clean.

For a bedroom ottoman intended to store bedding, the Edinburgh Embrace Blanket Box-style deep interior with fabric lining is a smart choice that keeps everything fresh and protected.

Common Beginner Mistakes to Avoid

Even experienced makers have off days. Here are the slip-ups that beginners most often make  and how to sidestep them:

Mistake

Why It Happens

How to Avoid It

Cutting panels too small

Measuring once and cutting

Measure twice, cut once — always

Forgetting to account for fabric thickness

No allowance in lid sizing

Add 1.5–2cm buffer to lid sizing

Skipping pre-drilling

In a rush

Always pre-drill into MDF or plywood edges

Stapling fabric while it's slack

Not pulling fabric taut

Keep constant tension as you staple

Not testing hinges before upholstering

Eager to finish

Attach and test all hardware before fabric goes on

Using low-density foam

Buying on price alone

Always use 40kg/m³ or higher density foam

Frequently Asked Questions

1. How long does it take to build an ottoman box with storage from scratch?

For a first-time builder working at a relaxed pace, expect to spend around 8–12 hours across the full project. This breaks down to roughly 2–3 hours for cutting and assembling the frame, 1–2 hours for the lid, and 3–5 hours for upholstery. Spreading it over a weekend is the most comfortable approach.

2. Do I need any special woodworking experience to build an ottoman box?

Not at all. This is genuinely one of the most beginner-friendly furniture builds out there. If you can measure, cut a straight line, and drive a screw, you've got the skills needed. The upholstery side takes a bit of patience rather than technical expertise.

3. What's the best fabric for a storage ottoman that will be used as a seat daily?

For heavy daily use, a fabric with a high rub count (measured in Martindale rubs) is the way to go. Aim for 25,000+ Martindale for a seat used every day. Good options include velvet (100,000+ rubs on quality versions), faux leather, and tightly woven linen blends.

4. Can I build this without a saw?

Yes, timber merchants and some hardware stores (like B&Q in the UK) offer a panel-cutting service. Bring your cut list, have them do the cuts, and you can assemble the whole box with just a drill and screwdriver. It's a perfectly valid approach.

5. How much weight can a DIY storage ottoman lid hold?

With 18mm plywood or MDF and a properly attached piano hinge, the lid can comfortably hold 100–150kg, more than enough for two adults sitting side by side. The key factor is the hinge and the strength of the lid panel, not the foam.

6. How do I stop the inside of the ottoman from smelling musty?

A few sachets of activated charcoal or baking soda placed inside the box will absorb moisture and odours. Cedar lining, as mentioned earlier, is an excellent long-term solution. Also, make sure stored items are clean and dry before placing them inside.

7. Is MDF or plywood better for a beginner building an ottoman?

MDF wins for most beginner builds. It's smoother, cheaper, easier to cut cleanly, and gives a flatter surface for fabric. Plywood is stronger and lighter but costs more and can splinter at the edges if cut without the right blade. Stick with MDF for your first build.

Final Thoughts

Building your own ottoman box with storage is one of the most satisfying beginner woodworking projects you can take on. It's practical, customisable, and the result is a piece of real furniture you'll use every single day. The process covers all the basics, measuring, cutting, assembling, and upholstering, giving you skills that translate directly to more ambitious projects down the road.

If you'd like some inspiration for shapes, fabrics, and finishes before you start, browsing ready-made options like the range at The Bed Store is a great way to get a feel for what's possible. Pay attention to the lid profiles, leg styles, and fabric choices that catch your eye, and incorporate those ideas into your own design.

Take your time with each stage, don't skip the prep work, and trust the process. Your finished ottoman box will be well worth the effort, and every time you lift that lid to grab a blanket, you'll be quietly chuffed that you built it yourself.
