I don't sell any of these nor do I receive any remuneration if you buy them, and I have not personally reviewed all of them, they are listed here to give you perspective
Introduction
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
Common features
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
you must ensure the valves are rotated into inflate mode AND the valve caps are firmly screwed on to avoid air leakage overnight
avoid placing near heat sources as this may cause air pressures to rise too much
max 1psi - so cannot use pumps designed for air tents, etc which will have a high risk of over-inflation
you need to manually deflate it a little during warm day times
obviously you need to ensure there are no sharp objects which may puncture it - including under the tent floor
Single bed
“Aero-Frame” base is 75D polyester TPU and designed for maximum load of 150kg
“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 = 1.1m3
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
