• air beds, mattresses and stretchers for camping

• the NZ company Zempire introduced a unique new air bed design in 2024 which they named “Monstabed”
• it takes the benefits of a traditional air bed (height) and addresses the air bed design's main weakness of poor insulation by permanently attaching their foam self-inflating 10cm, insulated MonstaMat on top of the “Aero-Frame” base air bed
• don't confuse with the Zempire Monstamat which does not have the “Aero-Frame” base air bed

• unlike many traditional air beds there is no PVC as it uses TPU instead which is healthier for you and the environment
  • TPU is biodegradable and recyclable, does not require toxic chemical treatments or plasticizers like phthalates, and have less odor and off-gassing compared to PVC
• each section (air bed and Monstamat top layer) have 360deg valves with screw on caps
  • max 1psi - so advise to use the optional dedicated Zempire rechargeable air pump “Monstapump” which will hopefully prevent over-inflation
  • highly recommend buying the optional matched Zempire MonstaPump air pump (or use a quieter manual hand pump if you can find one to fit) which has an attachment which screws onto these valves and will greatly assist inflation and deflation
  • manual deflation without a pump is time consuming
• top Monstamat section is 10cm thick 3D open cell foam and has R value 10.5 and top is “no-noise” 130D polyester TPU with 150D polyester TPU walls

• “Aero-Frame” base is 75D polyester TPU and designed for maximum load of 150kg
• 195x80x42cm;

• “Aero-Frame” base is 150D polyester TPU and designed for maximum inflation of 1psi and max load of 300kg
  • according to my simplistic maths, the surface of the top is ~4000 sq inches and so a load of 300kg spread evenly across it would equate to an increased pressure of (300*2.2/4000 = 0.2psi)
  • the effect of warming during the day: pressure at final temp = pressure at start temp * final temp in K / start temp in K
    • thus if pump it up at 15degC to 1 psi and it heats up to 30degC, the pressure at 30degC = 1 x 303 / 288 = 1.05psi, if it should heat to 50degC then pressure would be 1.2psi
• 195x135x42cm;
• it is too wide for most 2P hiking tents
  • you need the 135cm width at the height of the top of the bed which is 42cm - most 2P hiking tents get narrower as you go up from the floor
  • most 2P or 3P tents are 220cm long so length is not usually the issue
  • it will NOT fit inside:
    • Vidalido Land Yu 2Persons TC Cotton S-T139 Tent (150cm wide floor)
  • it will fit inside:
    • the 2P version of the 3f UL Gear TC cotton Kangaro inner tents 160cm wide floor - very snug fit with just enough room at the ends to use the pump
    • 3P version of the Goout Springhill Penglai Kangaro TC bird-wing style tents 195cm wide floor
      • the 2P version is 155cm wide floor so it might just fit but I doubt it?
    • 3P or larger tents - 3P tents are usually have a 175cm wide floor as a minimum
• packs to 78x35x35cm;
• 8.4kg;
• https://www.zempire.au/monstabed-twin RRP $AU449
• if you have room for this in your car and your tent, it is a great option for comfort and warmth

• lithium battery rechargeable via USB-C
• uses 4.8Wh to inflate or deflate the twin bed;
• compact size
• comes in nice zip case and has a plastic shield to put on the end to avoid inadvertent switching on during transit
• inflates or deflates (just attach the adapter to the deflate port instead of the main inflate port)
