reclining garden chair or weather proof bed for elderly dad

[DoggerelBank]

Can anyone recommend a good garden recliner chair for my very elderly, frail and disabled dad? He loves sunbathing, and doesn't care about skin cancer (he's old enough now that SOMETHING's going to kill him pretty soon). But the garden recliner he has is too low and unsteady, so once he's lain down and slept, he can't get up, and Mum can't help. So he's given up on going outside.

Ideally we'd get him an electric riser recliner armchair like in the sitting room, but they don't seem to be weather proof. Are there any that are light enough and have wheels good enough for a very frail person to push in and out of the house, over a slight bump at the hall/garden threshold? Or are there any garden chairs that are near enough to a bed height and sturdiness to work for him (he can still get in and out of bed OK)?

This looks OK

Or would he manage this?

Thanks, everyone. I'll have a good look at all the suggestions.

A tip which might help him is one given to my father who had Parkinson’s. He struggled to get up out of a chair until he was told to lean forward and look at the floor, shifting his centre of gravity. He could then push himself up to standing using the arms of the chair much more easily.

My dad had similar to this

Leaves it outside and covers it
