Inflatable mattress and airbed FAQs
Got questions before you hit “buy”? These FAQs cover the stuff that actually matters in real life - from overnight deflation and back support to what’s safest for kids and camping.
What’s the best airbed for overnight guests (that won’t go saggy by 3am)?
If you want something that feels most like a ‘proper bed’, look for three things: height, firmness control and stability. A raised airbed (around 40 to 50cm) is easier to get in and out of, adjustable firmness helps you dial in comfort and a solid internal structure (coils/air chambers) stops that annoying ‘roll into the middle’ feeling.
For most households, the Vango Blissful Double Airbed with Built-in Electric Pump ticks those boxes and has a silent top-up feature designed to prevent overnight pressure drops, so guests don’t wake up on the floor.
Why do air mattresses deflate overnight and how do you stop it?
Even without a puncture, it’s normal for an airbed to seem softer by morning. The main culprit is temperature: when the air inside cools overnight, it contracts and the bed feels less firm. New airbeds can also ‘relax’ a bit on first use as the material stretches and uneven weight distribution can exaggerate the dip.
To reduce air loss:
Create a base: place a blanket, mat or insulated layer underneath (especially for camping).
Let it settle: on first use, inflate to about 90%, leave 20 to 30 minutes, then top up.
Don’t overfill: rock-hard inflation can stress seams and make sagging feel worse later.
Pick an auto top-up model: if you’ve got mains power, some beds (like the Vango Blissful and Huddle Never Deflate) are designed to quietly add air overnight.
Are self-inflating mats warmer than airbeds for camping - and what should you buy?
Usually, yes. For camping, warmth is about what’s between you and the cold ground. Standard airbeds can feel chilly because they’re basically a big pocket of air, while self-inflating mats use insulating foam as well as air, so they tend to be warmer, quieter and more stable.
Look for:
Thickness: roughly 7 to 10cm is a good comfort range for car camping.
Easy deflation/pack-down: nobody wants a wrestling match at 7am.
Repairability: patches and robust valves matter if you camp often.
If you’re camping in colder weather, add an insulated layer underneath and pair with a decent sleeping bag.
What’s the best airbed for bad backs?
For sore backs or limited mobility, focus on a raised airbed (easier in/out) and a stable, supportive build (coils/air chambers rather than a wobbly single-layer mattress). Adjustable firmness can help you find the “sweet spot” between too soft and too hard.
In this guide, raised options like Yawn Air (stable structure) or adjustable models like Vango Blissful or Huddle can work well.
What size airbed should I get (single, double, king) - and are they true-to-size?
Air beds and inflatable mattresses are generally true to size, although they can vary by a small margin depending on inflation levels and the thickness of flocked toppings.
As a general rule:
Single: best for a child/teen or one adult with minimal space
Double: good for one adult who wants room, or occasional couples
King: best for two adults and longer stays
If you’re using it for guests, a bigger size often feels more comfortable because there’s less chance of rolling into the middle.
Built-in pump vs separate pump: which is better?
As long as you have access to the mains, built-in pumps are the most efficient and convenient choice. Integrated into the airbed, they inflate incredibly fast. Some even top up automatically overnight to prevent sagging. While they can be heavy, airbeds with built-in pumps generally pack away into a compact carry bag for easy storage.
That said, airbeds that come without a pump are cheaper, and if you already have a pump, this is a more affordable option. Most hand or foot pumps are universal, doubling as a tool for your paddling pool come summer.
Is an airbed OK for a child - and what age can they sleep on one?
For most families, an airbed is a perfectly practical option for sleepovers, holidays and visits to grandparents - but age matters. Avoid using adult airbeds for babies and young toddlers; for little ones, you want a firm, flat, age-appropriate sleep space.
If you’re buying for a child, look for:
Kid-specific designs (travel beds with raised sides or a ReadyBed-style set)
Low profile (closer to the ground = fewer tumbles)
Good stability (so it doesn’t tip when they climb in/out)
A sensible max-weight rating (check the spec)
Practical tip: inflate it earlier in the evening and give it a short settling period, then top up - it often feels firmer and more comfortable. We recommend picking one made specifically for children, such as the INTEX Kids Travel Bed.
How to fix a puncture quickly?
Many airbeds come with a PVC repair patch for small tears, holes, or punctures, but if you don’t have one to hand, puncture repair kits from your bike or paddling pool will do the trick. Worst case, or for a last-ditch save, Gorilla-style tape or duct tape should be enough to last the night - just make sure the surface is clean and dry before you stick anything down.
