Simond MT500 Review: A Budget Camping Mattress for Festivals (2026)

The Simond MT500 XL trekking mattress is a game-changer for budget-conscious campers and outdoor enthusiasts. At just £49.99, it offers a level of comfort and convenience that rivals more expensive options. But is it worth the hype? Let's dive in and explore the pros and cons of this lightweight sleeping pad.

A Bargain for the Budget-Conscious

One of the most appealing aspects of the Simond MT500 is its price point. For under £50, you get a mattress that packs a punch in terms of features and performance. It's a far cry from the thin, uncomfortable foam mats or bulky, puncture-prone airbeds that have traditionally been the only options for budget-conscious campers. The MT500 strikes a perfect balance between comfort, packability, and affordability, making it an attractive choice for those who want to get the most out of their outdoor adventures without breaking the bank.

Comfort and Durability

The MT500 XL measures 195cm by 60cm, providing ample space for taller campers or those who like to sprawl. Its internal air chambers, running lengthways, offer 5cm of cushioning, which is more than many budget self-inflating mats. This design seems to absorb pressure from small rocks and uneven ground, providing a comfortable sleeping surface. While it's not as comfortable as thicker, premium sleeping pads, it's still very comfortable for the price. The mattress also has an R value of 1.5, making it suitable for warm weather camping.

Easy to Use and Pack Away

Inflating the MT500 is a breeze, taking less than a minute by mouth. The one-way inflation valve allows you to gradually reduce the pressure once you're lying down. Silicone patches on the upper surface help prevent sleeping bags from sliding off, and the mattress is easy to deflate and pack away. Rolled up, it takes up about the same space as a 1-litre water bottle, making it highly packable and perfect for backpacking trips or festivals.

Durability and Sustainability

The MT500 is made from synthetic materials and laminated components, which are hard to recycle at the end of their life. However, its durability suggests it will last for several seasons, improving its sustainability profile. The mattress has received high praise from users, with a solid 4.5/5 rating on Decathlon's website. It can be fixed with a self-adhesive repair patch, and Decathlon offers a two-year warranty against defective materials or workmanship.

The Bottom Line

The Simond MT500 XL trekking mattress is an excellent choice for those who want a comfortable, packable, and affordable sleeping pad. It's quick and easy to use, and its durability suggests it will last for several seasons. While it may not be as luxurious as more expensive options, it's a great value for money and a solid choice for budget-conscious campers and outdoor enthusiasts.
