### ⭐⭐⭐⭐⭐ Comfortable and sturdy
*by A***. on 22 October 2025*

### ⭐⭐⭐⭐⭐ Superb
*by M***Y on 22 July 2024*

Great product! Strong, light packs down to nothing. Worth the money.

### ⭐ Poor quality
*by K***. on 28 September 2025*

Very thin, almost see through. Very difficult to pack it back once unfolded. Not worth the price. Bear in mind that this is a third party company, they advertise a free returns option, but that’s not the case. Very misleading, avoid them!
