Sizes range from single-user novelty floats (around 46 x 40 inches) up to multi-person inflatable platforms. Example platform sizes shown include 6 ft x 5 ft, 8 ft x 6 ft, and 10 ft x 6 ft.
Weight capacities vary widely: baby floats can be as low as about 33 pounds, while large inflatable platforms can support roughly 1,000 pounds. Intermediate examples include capacities around 154, 176, and 400 pounds.
Products cover a broad span: baby floats are typically labeled for about 9 months and up; toddler/novelty floats often start around 2 years and up; larger kids/adult floats are commonly listed for ages such as 8 years and up or 10 years and up.
Most floats are made from PVC (polyvinyl chloride) or other plastics. Some baby floats also include polyester fabric and steel components, and certain platforms note heavy-duty PVC construction.
Larger inflatable platforms are sized for small groups: a 6 ft x 5 ft model commonly holds about 3–5 people, an 8 ft x 6 ft about 4–6 people, and a 10 ft x 6 ft about 5–8 people.
