I’ve got a Wychwood super light recliner, which on a couple of occasions I’ve tilted it fully back and rested my feet on an unhooking mat placed on top of a cooler bag...maybe 3-4 hrs kip at best, not really sure I’d recommend it though..
As a chair it’s very comfortable, too comfy in fact, I prefer the Fox adjusta level which strikes the right balance between stopping my backside from going numb but not so comfy I could doze off and miss a bite.
The Daiwa posted above looks a tidy bit of kit as a duel use chair, you might be able to make it sturdier by adding a single clamp on bed chair support leg, you might be able to pick one up for £10-15.
