Simond MT500 Review: Best Budget Camping Mattress for Festivals 2026

The Simond MT500 review proves that a quality budget camping mattress doesn't have to break the bank. Priced at just £44.99 for the standard size, this lightweight sleeping pad from Decathlon is ideal for festivals, car camping, and warm-weather adventures. In this review, we test its comfort, pack size, and value against premium alternatives.

First Impressions of the Simond MT500 Sleeping Pad

The MT500 arrives rolled into a compact package about the size of a large water bottle. At 680 grams (standard size), it's light enough for backpacking yet plush enough for side sleepers. The 7.6 cm thickness provides ample cushioning, and the air-baffled chambers offer stability without the wobble of traditional airbeds.

Unboxing and Setup

Unrolling the pad reveals a matt finish that reduces slipping on tent floors. Inflation is straightforward: turn the valve to “inflate,” give it a few breaths, and in under a minute you have a firm sleeping surface. The included stuff sack doubles as a pump – just trap air and press – but blowing directly works fine.

Performance on the Ground

We tested the Simond MT500 on rocky campsite ground and uneven grass. The 7.6 cm thickness effectively isolated us from roots and stones. For side sleepers, the pad’s internal baffles prevent bottoming out, though those with wider hips may prefer the XL version (10 cm wider) for extra hip room.

Comfort Comparison: MT500 vs Therm-a-Rest NeoAir

To see how the budget option stacks up, we compared it to the Therm-a-Rest NeoAir – a premium pad costing over £150. The table below highlights key differences:

While the NeoAir is lighter and more insulated, the MT500 costs roughly a third of the price and performs excellently for three-season use. For festival goers who only camp in summer, the MT500’s lower R-value is perfectly adequate.

Key Takeaways

• Best value – unmatched for under £50, especially for occasional campers.
• Comfortable for side sleepers – 7.6 cm thickness and air baffles reduce pressure points.
• Compact and lightweight – rolls down small enough for a daypack.
• Quick inflation – integrated valve allows easy setup without a separate pump.
• Limited insulation – R-value 1.5 means it’s only suitable for warm weather (above 10°C).

Who Should Buy the Simond MT500?

This pad is perfect for festival campers, summer caravanners, and backpackers on a budget. If you primarily camp in spring through autumn and don’t need extreme insulation, the MT500 offers a fantastic balance of weight, comfort, and price. For winter mountaineering or high-altitude trips, look for an insulated version.

Pros and Cons at a Glance

Pros: Affordable, light, comfortable, easy to pack, durable 40 denier fabric. Cons: Low R-value, no included repair kit, valve can be slightly slow to deflate.
