Hi Blanchie - I read your posting and feel that i can help - Beacons Products are foam rubber converters based in South Wales - under the brand name Multimat we make camping mats for the Outdoor Industry - we have 25 years experience and supply 50% of the UK market; partly under our own brand name and partly under the brand name of others companies active in the outdoor industry with our main competition coming in from China which we generally refer to as play mats. We used to make the old Karrimats for Karrimor upuntil about 5 years ago before their demise which is when we focused on developing our own brand name having lost such a good global distributor.
The Multimat Extreme XL is the Old Karrimat using Evazote 35kg/m3 foam - extremely tough and durable and will porbably last you 25 years (available in a range of thicknesses and sizes) - the same foam is used on the Summit mattresses in a thin 4mm layer which is then laminated to 8mm of the superlight high insulating foam from the Adventure Range to give a thick low weight high insulating mattress (not as tough as the extreme but a good trade off with less weight per vollume and improved insulation)- both models come inclusive of eyelets and webbing straps.
The Adventure mats are produced using a very low weight 18kg/m3 closed cell foam - low weight meaning more insulation per mm of thickness - these are pretty durable for most applications but not up to the same pounding as the Extreme mentioned earlier if you are on an unsupported expedition - the Adventure mats come inclusive of eyelets and webbing straps.
The Discovery mat offers excellent value for money, produced from a very good grade of foam and at 29kg/m3 will probably be very suitable for you - instead of eyelets and webbing straps - these mats come with cheaper elasticated strechy bands.
The differnece in prices are explained by very different qualities and different processing techniques - the lower the weight or size - the lower the price would follow if the same grades were used but they are not !
I hope that i ahve gone some to help you understand the differences.
Happy Camping !
