Raised dog bed size ?

I’ve been offered a raised dog bed for Hunter. It’s practically new, never been used and I thought if it was big enough would be a good idea for in the kennel. Not that Hunter will be spending much time in the kennel. Does anybody know what size raised bed is big enough for a fully grown lab. This bed is 90cm by 80cm and suitable for up to 50kg. The weight is ok but I’m not sure 90cm will be long enough :unsure:
