When choosing a new self inflatable mats, please keep the following considerations in mind:
Car camping: When you are not limited by size and weight, you can choose a thicker and larger mattress to ensure a comfortable sleep. These are usually cheaper than lightweight ones. Self-inflating cushions are usually a good choice for car camping.
(Large air mattresses are another option, if you want to use ordinary bed sheets and blankets instead of sleeping bags. However, these mattresses are relatively heavy and bulky and lack heat insulation, so they are best for mild environments. The pump needs proper inflation.)
Backpack: Those who like to enjoy a good sleep comfort while backpacking (or riding a bicycle, canoe or kayak) can choose to automatically inflate or air cushion, providing various thicknesses, durability, insulation value and weight. The optional chair kit gives your auto-inflation or air cushion dual functions and can be used as a comfortable seat with a backrest. For backpackers, this can be a lightweight luxury
Minimalist backpack: low weight and small package size surpass all other factors. An ultra-light air cushion may be your best choice. Some insulated full-length air cushions now weigh less than one pound. Please make sure to check the package size of your pad option in the store and consider it in your decision.
Crossing: Here, light weight is important, but long-term durability is also key. Closed-cell foam cushion is your best choice. Many hikers choose "short" or "3 / 4-length" foam cushions to reduce weight (you can put empty bags or extra clothes under your feet to get a little insulation if needed).
Winter camping: Camping on snow requires more insulation. REI recommends the use of two pads: an insulated high-R air cushion or self-closing cushion, located on top of the closed-cell foam cushion. The closed-cell foam pad adds insulation and provides insurance when the inflatable pad is punctured.
