Too many choices. Need to establish selection priorities, influenced by advertising:

• xp: thorns and splinters .. common in all cheap straw/bamboo mats
• xp: foldable .. the roll-up models (all bamboo mats?) generally take up much bigger storage space.
• product pictures: the more (Lazada) the better. Remember to top up the wallet and use up full balance.
• durability
• lglp: cooling … I foresee very small differences between products. I will rely more on A/C, and perhaps wet towel
• lglp: flip side
• lglp: weight

— plastic or synthetic fiber .. I didn’t like my plastic mats, woven with plastic “bamboo” strips . Now, most economical rattan mats are actually rayon, made from real rattan but chemically synthesized. You can call it chemical plant fiber, not raw rattan! Raw rattan mat is rare and expensive. So if you don’t like synthetic material, then your best bet is the mahjong mat.

— Q: Do I have tBudget to experiment 3 models?

Given a total budget of $300, $Cost is likely to be a LGlp for each purchase. Focus on tCost of cleaning, storage,,

If no good, just discard and buy another, until we find a good model.

Shall we favor high quality, high confidence models?
