Doesn't seem too much higher than the Rogers Goosebusters I've used. If it's comfy I'd say it's worth the extra brush in effort! Divebomb just dropped a layout chair that's very intriguing.
A lot of companies have that chair like divebomb one on Amazon a bit more but it’s in stika pattern and bulk decoy club different design I seen others on RU-vid after looking into after seen them on there too haha
The bottom has a enclosed waterproof tarpaulin floor. I've only used it in mud so I couldn't tell you it definitely keeps you dry in water. But it has the zero-gravity chair design-keeping you off the ground as well.
It's about as comfortable as one could get. Like I said the only downside is that it's a little harder to brush in being a higher profile. But the comfort is spot on.
