Care & Longevity

Natural wood offers a warm, organic feel that ages beautifully. Variation in the grain means the exact look may vary from piece to piece.
Care: To clean, use a damp cloth and pH-neutral detergent, then wipe dry. Avoid contact with acidic liquids, such as soda, fruit juice or vinegar. Any spills should be cleaned with lukewarm water immediately. Do not use acid or bleach-based cleaning products as they may affect the waterproofing and create permanent stains.
These pieces are easy to move around—use care to stack them gently and place within the felted channel to help.

FAQ

Free delivery and assembly? What's the catch?

Sundays provides complimentary delivery on all items, regardless of size or price, to all Canadian provinces and across the continental US. For larger items, including sofas, beds and dining tables, we also provide free in-home assembly and removal of packaging. There is no catch—we feel that delivery and set up should be as efficient as possible.

If you would like to ship your order to the Canadian Territories, Hawaii or Alaska please reach out to our Customer Care team to support processing your order. Note, an incremental shipping fee will apply.

How do returns work?

If something doesn't work for you, we will make it right. Returns for refund or exchange will be accepted within 30 days of delivery in original condition. See our return policy for more details.

Do you offer a warranty on your products? What is covered?

Yes! As of August 22, 2025, all purchases are covered by a limited five-year warranty, which protects against confirmed imperfections in manufacturing or craftsmanship starting from the day your order is delivered. Purchases made prior to this date remain covered under our previous two-year warranty.

There are a few limitations and exceptions, which you can explore in more detail on our warranty page.

Can I pay for my order in installments?

Yes! We are partnered with Shop Pay Installments, allowing you to split your purchase into regular payments. We offer two options:

- Four biweekly, interest-free payments, for orders from $50 to $999.99.

- Monthly payments, for orders from $150 to $17,500.

For more information on how it works, see the Shop Pay Installments FAQ.

What kind of wood do you use?

We use solid woods, particularly hardwoods like oak, walnut and ash. We choose these materials because they look great, hold up for years, and reflect our commitment to lasting quality. Softwoods (like pine or fir) are lighter and more prone to dents and wear, while hardwoods hold their shape, resist everyday knocks, and maintain their finish for years. Solid wood offers a warm, organic feel that ages beautifully, with natural grain variation that makes every piece unique. It also stands the test of time and develops character as it ages.

Really nice modular storage system!
I own both the open and closed Keep Stacking Storage System boxes in white oak and I really love them! They're perfect for my apartment and I really like how I can arrange them in whatever configuration I want. I think the product photos are accurate in terms of the color of the wood. Keep in mind that wood is a natural material so there will be some variation with the pattern and grain of the wood but if you buy multiple of these and put them side by side, they all match nicely. I especially like the fact that these are not made from particle board - they're really nice quality and will last a long time with care. The hinge for the closed box works great - it opens slowly and smoothly which I appreciate (you don't have to worry about the door flopping open suddenly). I also purchased the lids separately for these boxes because even though the closed version of the box has a top surface, the lids create a nice flat even surface across all boxes if you're planning to arrange both open and closed boxes next to each other like a sideboard.
Overall, I recommend these if you're looking for a modular storage system solution for your home!

Great entry table for us
Beautiful piece. We are using an open and door cabinet for shoes and things by front door. It provides some great storage and finishes our entry space nicely.

Perfect for Storing LP records!
I had two problems, more storage for my jazz record collection, and a rather specific spot in my condo, where I could place a shelving unit. I didn't want anything too high as a wooden record crate would be on top. The Keep Stacking Storage system worked perfectly!

So versatile
Moving this piece around my space and finding it is solving so many problems. The proportions are so good and love the ability to stack or make a bench. Obsessed with this system.

Works well for what we need!
Overall good build quality and packaged amazingly, but still arrived with some scratches and dings. Can't see how this happened during shipping based on how well it was packed, so likely occurred before all of that.
The only other complaint is that they're a bit tough to open. We're using them as nightstands and the angle we're at and would want to open them from isn't the easiest. The magnet that keeps it close is very strong and the mechanism that creates a smooth swing makes it a slow process to open all the way. Not a deal breaker, just not the most intuitive.
Other than that love that they're modular, so if we don't want to use them as nightstands forever, they can easily be used for a multitude of other options in the home. Happy with them!
