  Product Description
The Outwell Sleepnest Single 14cm self-inflating mat addresses a specific problem for campers who find standard 5-10cm mats too thin but don't want the bulk of double-thickness alternatives. This 200 x 73cm mat uses zoned support technology with strategically placed cut-outs through the foam core, which means you get proper cushioning where your shoulders and hips need it most, while unnecessary material is removed elsewhere. The result is a 14cm profile that actually packs down to 75 x 23cm, smaller than many thinner mats without integrated cut-outs. At 4.05kg it's not a lightweight backpacking option, but for car camping, caravan awnings or motorhome expeditions where you're prioritising sleep quality over pack weight, it makes sense.

The construction combines TPU lamination with 30D stretch polyester on the top and sides. TPU bonds directly to the fabric rather than being glued, which eliminates the delamination issues that plague traditional PVC mats after a few seasons of temperature changes. The stretch polyester gives against your body rather than feeling rigid like standard polyester weaves. Outwell's Double Flat High-Flow valve system speeds up both inflation and deflation significantly compared to single-valve designs. You'll still need to give it 5-10 minutes to self-inflate fully on first use, then top it up with a few breaths to your preferred firmness. The foam cavities are larger than typical self-inflating mats, which helps with initial inflation speed and reduces the overall weight.

This mat works on any surface but performs best on groundsheets or tent footprints rather than directly on rough ground, as the 190T 75D base fabric is tough but not puncture-proof. The 73cm width is standard single sizing, though side sleepers who move around might find it a bit narrow compared to the 80-90cm width of some premium mats. It's PFAS-free, which matters if you're concerned about forever chemicals in outdoor gear. The included carry bag has reinforced stitching at stress points and actually fits the rolled mat without needing to compress it excessively. Outwell backs this with their usual quality standards, and replacement valves are available separately if needed years down the line.

Frequently Asked Questions

How does the Outwell Sleepnest 14cm compare to standard 5-10cm self-inflating mats?
The Sleepnest 14cm provides significantly more cushioning than standard 5-10cm camping mats through its zoned support system with strategic foam cut-outs. These cut-outs concentrate support where your shoulders and hips need it most while removing unnecessary material elsewhere. Despite being much thicker at 14cm, it packs down to 75 x 23cm, which is often smaller than traditional 10cm mats without this technology. The weight is 4.05kg compared to 2-3kg for thinner mats, making it better suited for car camping, caravan awnings or motorhome use rather than backpacking.
What makes TPU construction better than PVC for camping mats?
TPU (thermoplastic polyurethane) bonds directly to the fabric through lamination rather than being glued like PVC coatings. This eliminates delamination, which is when the coating separates from the fabric after repeated temperature changes and rolling. PVC-coated mats often develop bubbles and peeling after a few seasons, particularly around the edges and valve areas. The TPU on the Outwell Sleepnest is also combined with 30D stretch polyester that gives against your body rather than feeling rigid like standard polyester weaves with PVC coating.
How long does the Outwell Sleepnest take to self-inflate?
The Outwell Sleepnest 14cm takes 5-10 minutes to self-inflate fully on first use due to the extra large foam cavities inside. After the initial expansion, you'll need to add a few breaths through the Double Flat High-Flow valve to achieve your preferred firmness level. The High-Flow valve system moves air faster than traditional single-valve designs, which speeds up both inflation and deflation. Subsequent uses after the first inflation will be faster as the foam has already expanded. The larger foam cavities compared to standard self-inflating mats help with inflation speed while also reducing the packed weight.
Is the Outwell Sleepnest 14cm suitable for side sleepers?
The Outwell Sleepnest Single is 73cm wide, which is standard single camping mat sizing. Side sleepers who move around during the night might find this width limiting compared to premium mats that offer 80-90cm widths. The 14cm thickness provides excellent cushioning for side sleeping as it prevents your hip and shoulder from pressing through to the ground. The zoned support system places extra foam specifically in the hip and shoulder zones where side sleepers need it most. If width is a concern for side sleeping, consider whether you tend to stay still or move around during the night.
Can the Outwell Sleepnest be used directly on the ground?
The Outwell Sleepnest can be used on any surface but performs best on groundsheets or tent footprints rather than directly on rough ground. The base uses 190T 75D polyester fabric that is tough and durable but not completely puncture-proof against sharp stones, twigs or thorns. Using it directly on uneven rocky ground increases the risk of punctures. Inside a tent on a groundsheet, in a caravan awning or on a motorhome floor provides the best protection. If you need to use it on rough terrain, inspect and clear the ground first or use an additional protective layer underneath.
What does PFAS-free mean for the Outwell Sleepnest mat?
PFAS-free means the Outwell Sleepnest is manufactured without per- and polyfluoroalkyl substances, which are synthetic chemicals often called forever chemicals because they don't break down in the environment or human body. Many outdoor products historically used PFAS in water-resistant coatings and fabric treatments. The Outwell Sleepnest achieves its performance through TPU lamination and fabric construction without requiring PFAS chemicals. This matters for environmental impact and for campers concerned about chemical exposure in gear they sleep on for extended periods.
Can replacement parts be purchased for the Outwell Sleepnest?
Outwell provides replacement Double Flat High-Flow valves separately for the Sleepnest range, which extends the usable life of the mat if valve issues develop years after purchase. The valve is the most common wear point on self-inflating mats as it experiences repeated opening, closing and pressure changes. Having replaceable valves means you don't need to replace the entire mat if valve performance degrades over time. Outwell backs the Sleepnest with their standard quality guarantee. For specific replacement parts availability and compatibility, contact Outwell's UK support or authorised dealers who have access to the current parts catalogue.
How does the carry bag design affect the Outwell Sleepnest's longevity?
The Outwell Sleepnest carry bag features reinforced stitching at stress points where standard bags typically fail first, particularly around the opening and base seams. The bag is sized to fit the rolled mat at 75 x 23cm without requiring excessive compression, which protects both the bag and the mat from unnecessary strain. Many camping mat bags are too small and force you to compress the mat heavily, which can damage the foam core over time and causes bag seam failures. The proper sizing means you can store and transport the Sleepnest without fighting to fit it in, extending both the bag's life and maintaining the mat's self-inflating capability.
