Measuring 198 x 130 x 7.5cm, the Deluxe offers a sufficient length of 6ft 6” which should be ample for most of the adult population of the world – apart from Sultan Kosen perhaps. For those that don’t know, he’s the current world’s tallest man!

Fully-inflated dimensions are 201 x 132 x 10cm and so it can cater for somebody up to 6ft 7 in height. I found I had plenty of room at 6ft3 tall. In this article we concentrate on our experience and recommendations for the choice of best self inflating mattress, and so the size and weight of the product is of less concern than how comfortable it is and how well it stays inflated etc.There’s no denying that the SIM was comfortable for my wife though who is a much more svelte 11 stone. OK, 10.5 stone – she’s watching me type! The Shangri-La is for all intents and purposes a proper mattress when it’s fully inflated. It has vertical side walls to maximize the top-level surface area and this means that you don’t roll off in the night. Whether it’s a super comfy air mattress or something altogether more luxurious you’re looking for, we’ve rounded up some of the best luxury camp bed options for a comfortable night under canvas. It is a true 4-season sleeping pad with an R-Value of 6.8. This provides excellent insulation between you and the floor for effective winter-use.

In reality (unless you are a heavy person over 15 stone) a 7.5cm option is acceptable, but we wouldn’t recommend going any lower than that if comfort is your main objective. Inflation is simple and obviously doesn’t require a pump. Simply undo the valve and the air will gush in with full inflation after 5-10 minutes. At this point tighten up the valve and you are ready to climb on board. Inflated size for the Ultim is 200 x 136 x 8cm which is enough for most people under 6ft 6 inches in height. The Ultim In UseMeasuring 201 x 74 x 5cm when inflated, the IForrest includes both an integrated pillow and armrests for significant added comfort. What is great about the armrests is that they stop you rolling off the mattress in the night very effectively. If you are planning to use it on top of a camp bed then this is an important consideration – you might be a foot off the floor! In terms of dimensions and operation, the Dreamcatcher is pretty standard in most areas. However, the inflated size is a little restricted compared to the more expensive Vango and Berghaus options – the length is 195cm (just under 6ft5) and so we would recommend either of those two over the Outwell if you’re lanky like me. Dimensions are solid at 200 x 76 x 15cm for the ‘Grande’ size which is slightly wider than a conventional single – we appreciate Vango’s dedication in constantly supplying 200cm (6ft7) length mattresses instead of cutting cost by reducing too much. The most comfortable and luxurious single self-inflating mat from Zempire, the Monstamat Single provides a home-from-home feel on any camping trip. A 10cm self-inflating mat luxuriously coated in soft stretch fabric provides instant comfort. A 150D Polyester base provides durability and resilience against the hard ground, whilst the internal cross-core foam allows for fast inflation and ultimate comfort. The KingCamp is undoubtedly fabricated from decent materials – the two valves on the SIM are brass which is a nice touch and differentiates the Deluxe from other SIMs which rely on plastic.
