Sounds like the perfect solution!

Kibo more often is curled up, Sami is a sprawler!

I suggest instead of trying to find super king size dog bed you purchase a huge leather sofa instead. They will love that.

Single foam mattress from Ikea .... you could make washable cover, possibly duvet cover.

Look on freecycle for a second hand sofa. cover it with a throw or an elastic mattress cover. my Great danes always had that in the house. In the sleeping quarters for night OH made a wooden slatted bed with a memory foam mattress.

That's a GREAT idea.

Looks like we are going to try out one of the k9 hi rise beds plus going to get a nice roll of vet bed to velcro over the top for additional comfort.Sold our old sofa lastnight so want to get them new bed asap whilst there is nothing else in the front room for them to sit on lol(they stilll have their old bed)

Found this on ebay, 5ft x3ft roll of thick vetbed for £20!!
Bargain,will velcro this over the top for them.

Arrived today and the dogs love it,bit smaller than I pictured but they can both get on it easily.Although Dave prefers the new shaggy rug we got last night for the front room lol
Sorry for crappy phone pics.So seems a success although the poles that slot together has some rough/sharp edges with bits of swarf on,I also saw someone else complain of this on a youtube vid shame they havent rectified it!No danger to the dogs just the idiot thats putting it together!

Gorgeous picture of Roo - and Dave is as expressionless as always! I love your two!
