Whether you're furnishing a new condo in Liberty Village, restoring a Victorian heirloom in Cabbagetown, or outfitting an RV for life on the road, you've probably realized that a standard mattress doesn't always fit the bill.
Toronto is a city of unique spaces. Century-old rowhouses, modern lofts, converted heritage buildings, tiny condos with creative floor plans. Finding a mattress that actually fits your space is a more common challenge than most people expect.
This guide covers everything you need to know. Why you might need a custom size, how the pricing works, how to customize both the dimensions, including height, how to measure correctly, and where to find locally built custom mattresses right here in Toronto.
Why Go Custom? The Most Common Situations
Small Toronto Spaces and Condo Living
Toronto condos are known for their creative use of square footage. A standard bed can easily block a door, a radiator, or a built-in closet. Custom sizing lets you make the most of every inch. Sometimes shaving a few inches off the width is all it takes to make a bedroom work.
Unique Home Layouts and Built-In Beds
From tight attic nooks in Annex homes to alcove beds in Beach cottages, sometimes the architecture tells you what size you need. If the frame is already built into your home, you're working backwards from that space.
Antique and Heirloom Bed Frames
Antique bed frames predate modern sizing standards. A "double" from 1910 might measure 52" x 74" rather than today's 54" x 75". Heirloom four-posters, wrought iron frames, and imported European pieces almost never line up with modern standard sizes.
European and Imported Furniture
European mattress dimensions are metric, so they never land cleanly on North American standard sizes. A 160cm x 200cm European King (roughly 63" x 79") doesn't match any standard Canadian option.
Boats, Yachts, and Marine Applications
Marine sleep quarters are notorious for irregular shapes. V-berth cuts, rounded corners, tapered widths. A standard mattress simply can't be made to fit without custom cutting.
RV and Camper Living
RV manufacturers prioritize walkway space over bed dimensions. That's why most RVs use non-standard sizes like the Short Queen (60" x 75") or RV King (72" x 80"). Standard mattresses are typically 5 to 8 inches too long and will block slide-outs or closets.
Mobility and Accessibility Needs
This is one of the most overlooked reasons to go custom, and it matters a lot. Getting in and out of bed safely depends heavily on the combined height of your mattress and your foundation. Too low and it's hard to stand up. Too high and it's hard to sit down onto safely.
At Dozy, we can build mattresses in custom heights. Thinner profiles work great for loft beds or platform frames with limited overhead clearance. Thicker builds help people who need more height off the floor. Our foundations also come in different heights, which means we can set the exact total bed height that works for your body and your situation. That's something a standard retailer simply can't offer.

How Custom Mattress Pricing Works
The logic is simple: we always manufacture from the nearest standard size up.
Mattress materials (foam layers, coil units, quilted covers) are produced in standard dimensions. To build a non-standard size, we start with the closest larger standard size and cut or alter the materials down to what you need. Even a small deviation from standard requires a full step up in materials.
A Step-by-Step Pricing Example
Say you need a mattress that is 40" x 70".
- Find the nearest standard size up. A 40" width is wider than a Twin (38"), so the nearest standard size up is a Double (54" x 75").
- Start with the Double price. Say the Double is $600.
- Add 20% for the custom work. $600 x 1.20 = $720 for your 40" x 70" mattress.
That 20% covers the labour and material waste from cutting down a larger format. It is not a markup. It reflects the actual cost of making something that does not come off a standard production line.
Height Customization Pricing
Custom height works the same way. If you need a mattress thinner or thicker than our standard build, we adjust the internal layer stack. This typically adds 10 to 15% depending on how far it deviates from standard. Pair that with a custom-height foundation and we can hit nearly any total bed height you need.
What About Bedding?
Custom sheets are available through specialty bedding retailers. If you can't find what you need, any tailor can re-hem standard sheets to fit a custom size. It is usually inexpensive and much simpler than most people expect.
The Part Nobody Warns You About: The Frame Problem
Most mattress guides skip this part. We think it is important.
A custom mattress is the easy part. The custom bed frame is where things can get expensive and slow.
At Dozy, we can typically have a custom mattress ready in 2 to 7 business days. We manufacture locally in Toronto, so there is no container ship involved. But if you also need a non-standard bed frame, box spring, or platform base to match, that is where the real challenge begins.
Furniture manufacturing has largely moved offshore over the past few decades. The factories that once made custom frames in North America are mostly gone. What remains is a small number of local craftspeople and custom furniture shops who can do the work. Their lead times are long and their prices reflect the fact that they are one of the few options left. If you order a custom frame from overseas, you are often looking at 8 to 16 weeks and significant shipping costs.
Watch out for this trap: You get the mattress in a week, then wait months for the frame. Or you overpay locally because you have no other option. Figure out your frame situation before you order the mattress, not after.
If you are working with an existing antique or built-in frame, great. The mattress comes to you. If you need a new custom frame, start that search before you order the mattress.
One exception worth knowing: boxsprings. If a custom-height boxspring is all you need (rather than a full custom frame), we can usually help with that directly. We manufacture foundations locally alongside our mattresses.
How to Measure for a Custom Mattress
Getting the measurement right is critical. Custom mattresses are final sale. Here is how to do it properly.
Measure the Interior Frame Opening
Do not measure the outside of the frame. Measure the inside dimension, the actual space where the mattress will sit. For a slatted frame, measure corner to corner inside the rails.
Account for Clearance
For an enclosed frame with rails on all four sides, subtract half an inch from each dimension. This gives enough clearance that the mattress fits cleanly without being forced in, while still filling the space properly. For an open-sided platform bed with only a headboard and footboard, you have a bit more flexibility.
Check the Corners
Older frames sometimes have posts that intrude at the corners. Measure the open space between the posts if that applies. You may need a mattress with notched corners, which custom manufacturing handles easily.
Confirm Height and Total Bed Height
Measure your frame from the floor to the top of the slats or support surface. Then think about your target total bed height, the distance from the floor to the top of the mattress once it is sitting in place. The difference between those two numbers is your target mattress thickness.
If you are customizing for mobility or accessibility, remember that a foundation also adds height. Tell us your target total bed height and we will spec both the mattress thickness and foundation height to get you there.
Measure Twice
Custom orders are non-returnable. Measure the frame on two separate occasions, ideally with a second person confirming the numbers before you place your order.
