I love sitting on legs with Naïla. Installation is straightforward (20 minutes at all). She will lean 15 degrees toward the front on a otherwise flat ground. I find that very usefull at night as the sensation well replaces an alarm clock. I take care to land on flat and stone free places thus my landing places are few. Sand is very good for cockles down here in La Rochelle.
They were manfactured by “the leg company”, excellent quality.
Landing on mud, as otherwise mentionned, leads to water intake potential cloging problems (motor, toilets) that one should be aware of.
