65” TV height vs floating Kallax vs centre speaker vs receiver ergonomics — stuck on layout

I’m planning a 65” OLED (84 cm tall) with a 19 cm high centre speaker and a 17 cm high receiver. My seated eye level is 94 cm.

If I put an IKEA Kallax 4x1 (42 cm high) on the floor, the centre sits at 61 cm. Allowing 5 cm clearance, the TV bottom ends up around 66 cm and the screen centre around 108 cm. That’s about 14 cm above eye level, which seems acceptable.

I’d prefer to float the Kallax, for aesthetics and to hide the plug socket, ifI do this the top is 58 cm, the TV centre jumps to around 124 cm, which feels too high.

Ideally I’d also like the receiver at roughly hip/worktop height so I’m not kneeling to use it, but raising it under the TV pushes the screen even higher.

Would you prioritise perfect TV height and live with a low receiver, or compromise on screen height for better ergonomics? Is ~14 cm above eye level fine long term?
