Quick Answer: A double (full) air mattress measures 54 x 75 inches, the same footprint as a standard double bed. Raised models (18 to 22 inches high) feel more like a traditional bed, while low-profile versions (6 to 9 inches) pack better for camping. Expect to pay $60 to $200 in Canada, with built-in pump models starting around $80. For everyday sleeping, a permanent mattress is always preferable.

Double Air Mattress Sizes
A double air mattress matches standard double (full) bed dimensions: 54 inches wide by 75 inches long. This provides enough room for one adult to sleep comfortably or two adults in close quarters. Standard double fitted sheets will fit most double air mattresses, which is a practical advantage over odd-sized inflatable beds.
| Air Mattress Size | Dimensions | Best For | Price Range (CAD) |
|---|---|---|---|
| Twin | 38 x 75 in | Single sleeper, kids | $40-$120 |
| Double/Full | 54 x 75 in | One adult or cozy couple | $60-$200 |
| Queen | 60 x 80 in | Two adults, guest room | $80-$250 |
| King | 76 x 80 in | Maximum space | $120-$350 |
Raised vs. Low Profile
Raised Air Mattresses (18 to 22 inches)
Raised models sit at approximately bed height, making them easier to get in and out of. This matters for older guests or anyone with mobility issues. The higher profile also accommodates more air volume, which generally translates to better support and less "bottoming out." Most raised models include built-in electric pumps.
Low-Profile Air Mattresses (6 to 9 inches)
Compact models are designed for camping and travel. They pack smaller, weigh less, and often use manual or battery-powered pumps. The trade-off is comfort: at 6 to 9 inches, you feel the floor underneath, especially on hard surfaces. Adding a foam pad or blanket underneath helps.
Choosing the Right Height
For guest rooms and home use, choose a raised model (18+ inches). Your guests will thank you. For camping, car travel, or temporary floor sleeping, a low-profile model packs better. For cottages that need both, a mid-height model (12 to 15 inches) offers a reasonable compromise.

Pump Types and Inflation
| Pump Type | Inflation Time | Power Source | Noise | Best For |
|---|---|---|---|---|
| Built-in electric | 3-5 minutes | Wall outlet | Moderate | Home, guest rooms |
| External electric | 3-5 minutes | Wall outlet | Louder | Budget option |
| Battery-powered | 5-8 minutes | D batteries or rechargeable | Quiet | Camping, no outlet |
| Manual (hand/foot) | 10-20 minutes | Your effort | Silent | Backup, camping |
Never-Flat Technology
Some premium air mattresses include secondary pumps that monitor pressure and add air automatically throughout the night. Air mattresses naturally lose some pressure as the air cools overnight, which is why you wake up on a deflated mattress. Never-flat systems address this, though they add a quiet hum to the room.
Brad, Owner, 40+ years of experience: "Air mattresses are great for what they are: temporary sleep surfaces for guests and camping. But I have had customers come in after sleeping on an air mattress for months because they were 'getting by.' Your back deserves better than getting by. Even an entry-level proper mattress will outperform the best air mattress for nightly sleep."
Best Uses for a Double Air Mattress
When an Air Mattress Makes Sense
- Overnight guests: A raised air mattress in the guest room or living room
- Camping and cottages: Portable comfort away from home
- Moving and renovating: Temporary sleeping while furniture is in transit
- Kids sleepovers: Fun, easy to set up, easy to store
- Emergency preparedness: Part of your household emergency kit
Why Air Mattresses Are Not for Everyday Use
Research by Jacobson et al. (2008) in the Journal of Chiropractic Medicine confirmed that proper mattress support significantly affects back pain and sleep quality. Air mattresses lack the zoned support, consistent firmness, and pressure-relieving properties of traditional mattresses. Even the best air mattress creates a uniform pressure surface that does not adapt to body contours the way memory foam or pocket coils do.
Air Mattress vs. Real Mattress
| Factor | Air Mattress (Double) | Traditional Mattress (Double) |
|---|---|---|
| Price | $60-$200 | $400-$1,500 |
| Support | Uniform air pressure | Zoned coils or foam layers |
| Durability | 1-3 years | 7-10 years |
| Portability | Excellent | None |
| Partner disturbance | High (one moves, both feel it) | Low (pocket coils isolate motion) |
| Back support | Minimal | Engineered for spinal alignment |
| Temperature | Cold in winter (air cools) | Neutral to warm |

What size sheets fit a double air mattress?
Standard double (full) fitted sheets (54 x 75 inches) fit most double air mattresses. For raised models (18+ inches), use deep-pocket sheets designed for mattresses up to 22 inches thick to prevent the sheet from popping off overnight.
How long do double air mattresses last?
With careful use, a quality double air mattress lasts 1 to 3 years. Frequent use, pets, and rough surfaces shorten the lifespan. Keep a patch kit handy, as small punctures are the most common failure mode.
Can two adults sleep on a double air mattress?
Technically yes, but 54 inches gives each person only 27 inches of width, which is tight. A queen air mattress (60 inches) provides noticeably more room for couples. For a single adult, a double is very comfortable.
Why does my air mattress deflate overnight?
Air contracts as it cools, so some deflation is normal as your bedroom temperature drops overnight. Temperature changes, micro-leaks around the valve, and seam stress all contribute. Never-flat pump models compensate automatically.
