The Simond MT500 trekking mattress from Decathlon, priced at £44.99 for the standard L version or £49.99 for the XL, delivers impressive comfort and portability for summer camping and festivals. The mattress uses air-baffled chambers to provide 5cm of cushioning, rolling down to the size of a small water bottle.
Design and Features
The mattress has an R value of 1.5, suitable for overnight temperatures above about 8C. The XL version measures 195cm by 60cm, adding length and width for taller or broader sleepers. Silicone patches on the upper surface help prevent sleeping bags from sliding off. The mattress is inflated by mouth via a one-way valve, taking less than a minute.
Performance Testing
In tests, the lengthways air chambers absorbed pressure from rocks and uneven ground effectively. The mattress bends into a convex shape lengthways when inflated, requiring a sleeping bag and pillow to lie flat. The grooves of the air chambers are barely perceptible once inside a sleeping bag. Although not as comfortable as thicker premium pads, it is still very comfortable for the price.
Durability and Sustainability
The mattress is made from synthetic materials that are hard to recycle, but its durability supports long-term use. It has a 4.5/5 rating from hundreds of user reviews on Decathlon's website. Minor tears can be fixed with self-adhesive repair patches, and Decathlon offers a two-year warranty against defective materials.
Verdict
The Simond MT500 offers an excellent blend of comfort, packability, and ease of use for its price. It is practical for backpacking trips and festivals from late spring to early autumn. For colder nights, a mat with greater insulation is recommended. At this price, the Simond MT500 is difficult to beat.
