Quick Answer: A double bed in a box is a full-size mattress (54" x 75") compressed and rolled for doorstep delivery. Most reputable brands offer 90- to 120-night trial periods and free returns. Prices typically range from $400 to $1,200 depending on materials and brand. Setup takes about 10 minutes and the mattress fully expands within 24-48 hours.

What Is a Bed-in-a-Box Mattress?
The concept is straightforward enough. A mattress manufacturer compresses a foam or hybrid mattress using a vacuum-seal machine, rolls it tight, and ships it in a box roughly the size of a large duffel bag. You drag the box into your bedroom, cut the plastic, and watch the mattress expand over the next few hours.
It sounds almost too simple. And for a lot of people, it works well. The bed-in-a-box model took off in the 2010s when brands like Casper and Endy proved that Canadians would happily buy a mattress without lying on it first, as long as the trial period was generous enough to feel low-risk.
The appeal is obvious: no awkward mattress van blocking your driveway, no negotiating with a showroom salesperson, and a flat delivery fee that doesn't depend on how many flights of stairs you have.
That said, bed-in-a-box mattresses aren't perfect for everyone. We've had plenty of customers come into our Brantford showroom after a disappointing online purchase, looking for something they can actually feel before committing. More on that below.
How Does Compression Affect a Mattress?
Modern foam and hybrid mattresses are engineered to tolerate compression for short periods. The vacuum-seal process removes air from the foam cells, and the material rebounds once the plastic wrap is removed. Research published in materials science journals confirms that high-density polyurethane and memory foam recover their original properties after compression, provided the mattress is not stored compressed for extended periods (typically more than 2-3 months). If you receive a box mattress that has been sitting in a warehouse for months, full expansion may take longer than 48 hours.
Double/Full Size: What You Need to Know
The double and full mattress sizes are the same thing. In Canada, the terms are used interchangeably. The dimensions are 54 inches wide by 75 inches long (137 cm x 190 cm).
For context, that's 15 inches wider than a single/twin (39"). It's also 6 inches shorter than a queen (80"). If you're taller than 5'11", you may want to think carefully before choosing a double over a queen.
| Size | Width (inches) | Length (inches) | Width (cm) | Length (cm) | Best For |
|---|---|---|---|---|---|
| Single / Twin | 39" | 75" | 99 cm | 190 cm | Children, solo sleepers in small rooms |
| Double / Full | 54" | 75" | 137 cm | 190 cm | Solo adults, guest rooms, teens |
| Queen | 60" | 80" | 152 cm | 203 cm | Couples, taller sleepers |
| King | 76" | 80" | 193 cm | 203 cm | Couples with kids/pets, spacious rooms |
The double size is popular in older Canadian homes where the bedrooms were built when queen-size beds weren't yet the norm. If you live in a heritage home in Brantford's north end or in a classic bungalow with a 10x10 secondary bedroom, a double may genuinely be the better fit, not just the cheaper option.
Double Beds in Brantford Homes
Many homes in Brantford's established neighbourhoods, including Dufferin Avenue, Sydenham Street, and the West Brantford area, were built in the 1940s through 1970s. Secondary bedrooms in these homes often measure 10 x 10 or 10 x 11 feet. A queen-size bed can feel cramped in those rooms. A double gives you walking room on both sides and still fits an adult comfortably. If you're converting a guest room or setting up a home office that doubles as a sleep space, a double bed in a box can be a practical, cost-effective choice.
Brand Comparison for Double Size
Not every bed-in-a-box brand offers the same quality at the double size. Here's an honest look at the most popular options available to Canadian shoppers.
| Brand | Double Price (approx.) | Materials | Trial Period | Warranty | Made in Canada? |
|---|---|---|---|---|---|
| Endy | $795 | 3-layer foam | 365 nights | 15 years (with reg.; 10 without) | Yes |
| Casper | $850 | Foam + zoned support | 365 nights | 10 years | No (US-made) |
| Douglas | $699 | Gel memory foam | 120 nights | 15 years | Yes |
| Leesa | $899 | Foam hybrid | 365 nights | 10 years | No (US-made) |
| Novosbed | $749 | Memory foam | 120 nights | 15 years | Yes (Calgary) |
| Restonic ComfortCare (in-store) | Varies | 980 individually wrapped coils + foam | Comfort exchange in-store | 10 years | Yes |
One thing we notice: most bed-in-a-box brands at the double size are pure foam. If you prefer the responsive feel of coil springs, you'll typically need to step up to a hybrid model, which costs more and often ships in a larger box (or requires freight delivery).
Brad, Owner, 40+ years of experience: "Online mattresses have gotten much better over the years. But foam is foam. A lot of people come in after 90 nights and say it was fine for a while, then started feeling too warm or too soft. If you can come in and lie on something first, you'll know in five minutes what took you three months to figure out online."
That's not a knock on bed-in-a-box brands. It's just an honest observation from someone who has been fitting people to mattresses in Brantford for nearly four decades. The trial period exists for a reason.
Delivery, Unboxing, and Setup
One of the genuine advantages of a bed-in-a-box is that one person can handle delivery. The compressed box typically weighs between 25 and 45 kg for a double, depending on the materials. Standard parcel couriers like Purolator, FedEx, or Canada Post deliver to your door. You carry the box upstairs yourself.
What to Do When the Box Arrives
The process is simple, but a few steps make a difference:
Unboxing Steps for a Double Bed-in-a-Box
- Move the box to the bedroom first: Drag it to the correct room before cutting anything. An expanded mattress is much harder to manoeuvre through doorways.
- Lay it flat on your base: Place the rolled mattress on your slats, platform, or foundation before cutting the outer wrap.
- Use scissors, not a knife: A knife can easily nick the foam or fabric. Scissors give you better control.
- Cut slowly from the end: Slit the vacuum-sealed inner plastic from one end. The mattress will begin to expand as air enters.
- Wait before putting on sheets: Give it at least 4-6 hours before making the bed. Some manufacturers recommend 24-48 hours for full loft.
- Air it out if needed: A faint chemical smell (off-gassing) is normal with new foam. Opening a window helps it dissipate within 24 hours.
Does a Bed-in-a-Box Need a Box Spring?
Most bed-in-a-box mattresses do not require a box spring and are not designed for one. They work best on:
- A solid platform base (no slats)
- Slatted frames with slats no more than 3 inches (7.5 cm) apart
- Adjustable bases (check brand compatibility)
- The floor (works, but affects warranty with some brands)
Putting a modern foam mattress on a traditional box spring can cause uneven support and may void the warranty. Check the manufacturer's base requirements before setting up.
If you're shopping for a double bed with slats, we've covered the specific slat spacing requirements in detail. Getting the foundation right matters as much as the mattress itself.
Trial Periods and Return Policies
The trial period is the defining feature of the bed-in-a-box model. Most reputable Canadian brands offer 100 to 120 nights. That's roughly three to four months to decide.

Mattress Miracle now ships mattress-in-a-box options across Canada with free shipping included in the price. Browse our full mattress-in-a-box collection or call Brad at (519) 770-0001 to discuss which option suits you best.
How to Make the Most of a Trial Period
Sleep scientists recommend waiting at least 21 days before judging a new mattress. Your body adapts to a new sleep surface, and initial discomfort often fades. Give it at least three weeks before initiating a return. If it still doesn't feel right after a month, you're probably not going to love it. Most brands make returns painless: they arrange a pickup or donate the mattress to a local charity.
What the Trial Period Doesn't Cover
Trial periods are for comfort preference, not manufacturing defects. If there's a visible sag, indentation deeper than the brand's stated threshold (usually 1 to 1.5 inches), or a defect in materials, that's a warranty claim, not a trial return. Read the fine print on both documents before buying.
| Brand | Trial Length | Return Process | Refund Type |
|---|---|---|---|
| Endy | 365 nights | Pickup arranged; donated or recycled | Full refund |
| Douglas | 120 nights | Pickup arranged | Full refund |
| Casper | 365 nights | Pickup arranged | Full refund |
| Novosbed | 120 nights | Pickup arranged | Full refund |
One practical note: if you're in a smaller Ontario city or a rural area near Brantford, Paris, or St. George, confirm that the brand actually serves your postal code before purchasing. Some brands limit free pickup to major urban centres and charge a fee for rural returns.
In-Store vs. Online: Which Is Right for You?
We're a brick-and-mortar store, so you might expect us to be dismissive of online mattress brands. We're not. Some of our customers have had genuinely good experiences with bed-in-a-box purchases, particularly people who already know their preferred firmness and material preferences.
The honest answer is: it depends on what kind of decision-maker you are.
| Factor | Bed in a Box (Online) | In-Store (Mattress Miracle) |
|---|---|---|
| Try before you buy | No | Yes |
| Expert guidance | Chat/email support | In-person with Brad, Dorothy, or Talia |
| Delivery | Parcel courier, carry yourself | White glove: setup, positioning, packaging removal |
| Old mattress removal | Usually not included | Included with purchase |
| Trial period | 100-120 nights | Comfort exchange options available |
| Coil options | Limited (mainly foam) | Yes (Restonic, Sleep In) |
| Price range (double) | $400-$1,200 | Varies by model |
Our Restonic ComfortCare in a double size uses 980 individually wrapped coils, which provides a different kind of support than foam alone. It's particularly well-suited to people who sleep hot, since coil systems promote airflow through the mattress that foam layers don't replicate well.
If you've already owned a foam mattress and loved it, an online double bed in a box is a reasonable option. If you've never owned a foam mattress, or if you have back pain, hip pain, or shoulder issues, we'd encourage you to come in and try a few options first. Fifteen minutes on our showroom floor can save you a month of poor sleep.
We also carry mattress protectors and pillows that pair well with any new mattress, whether you bought it from us or not.
Dorothy, Sleep Specialist: "A lot of people assume they need a firm mattress because someone told them that decades ago. When they actually lie on a medium or medium-firm in the showroom, they're surprised. That's the kind of thing you can't discover online."
When a Bed-in-a-Box Makes Sense
- You're setting up a guest room and need a basic, decent mattress without a large budget
- You have a known preference for all-foam feel and just need a double size
- You live in a building with a small elevator where standard delivery is challenging
- You want to compare prices and are willing to use the trial period to test
When You Should Come Into a Showroom Instead
- You have chronic back, hip, or shoulder pain and need a specific support profile
- You or your partner sleep hot and need a tested breathable solution
- You want white glove delivery, frame assembly, and old mattress removal
- You prefer to make a purchase decision you know is right, rather than one you hope is right

How long does a double bed in a box take to fully expand?
Most foam and hybrid mattresses reach about 90% of their full height within 4-6 hours of unboxing. Full expansion typically takes 24-48 hours. You can sleep on it after a few hours, but waiting a full day before making the bed with sheets gives the foam time to settle properly.
Is a double bed in a box good for two people?
A double is 54 inches wide, which gives each person only 27 inches of space. That's workable for couples who sleep close together, but most sleep experts suggest a queen (60") or king (76") for two adults who want comfortable independent movement. If budget or room size is a constraint, a double can work short-term.
Can I return a bed-in-a-box mattress if it doesn't suit me?
Yes, provided you're within the trial period (usually 100-120 nights for major Canadian brands). The return process is straightforward: contact the brand, they arrange a pickup, and issue a full refund. Most donate the used mattress to a charity rather than resell it.
Does Mattress Miracle in Brantford carry bed-in-a-box style mattresses?
We carry coil-based mattresses including the Restonic ComfortCare and our Canadian-made Sleep In flippable line. Our double-size Restonic ComfortCare has 980 individually wrapped coils and delivers a feel that foam-only online mattresses don't replicate. We're happy to discuss all your options in-store at 441 1/2 West Street, Brantford.
What base should I use with a double bed in a box?
Most bed-in-a-box mattresses are designed for slatted frames with gaps no wider than 3 inches (7.5 cm), solid platform bases, or adjustable bases (check brand compatibility). They are not designed for traditional box springs. Using the wrong base can affect both comfort and warranty coverage.
