Size
The size of your floating water mat can make or break a trip to the lake. The best foam float mat will be big enough to accommodate your entire group, so no one gets left out of the fun. On the other hand, if you’ll be using it in your pool, make sure you choose one that’s not TOO big.
Weight Capacity
Weight capacity is also key. If you exceed the weight capacity of your mat, it will sink below the surface instead of floating on top of the water.
Note that manufacturer maximum weight capacities are usually under the best scenario where the weight is evenly distributed across the mat. If everyone is standing in the same area of the mat, some sinking will obviously occur in that spot.
Quality
If you’re looking for a floating water mat that will last season after season, choose a high-quality foam mat that won’t rip, tear, or puncture even with rough use. The price of inflatable water mats may be attractive but the experience will never be as good as a nice thick foam mat.
Foam vs. Inflatable
When deciding between a foam versus an inflatable floating water mat, it all comes down to price, convenience, and durability.
Foam mats never have to be inflated and they’re more durable, but they’re also bulkier when it comes to storage and transport and they cost more than inflatables. Inflatable mats are more compact when deflated, but you have to blow them up every time and they may puncture or tear more easily.
