Fixing points for sofa bed

[Matthew123456789]

Morning I've built up a sofa bed made of wood.the issue is it sits between the wheel arches and I cannot see anywhere to fix it in the sides. any ideas?

Thanks

How about the load lashing points?
Those are quite solid and designed to hold a load.

I did something similar. I didn't fix it on the sides, but take the plastic strip off just behind / in front / on top of rear bumper off and use the two empty threads to bolt 10 mm bolts / brackets to fix the back end of bed.
The front ends I bolt through the back seat brackets after removing them.
In practice, you don't need to overthink it - I've been using it for years without any problems, sometimes I don't even bother to put the bolts in and had no problem - the weight on top keeps it stable. It makes it easier if you drive through Dover / Calais / Dunkirk - as they sometimes look for stowaways in France and want to have a look underneath.
I cut a mattress to fit and once this is in, you don't think about it.

Most serious thing to consider is the height / size of space underneath. Worth making it so that standard plastic boxes (like Ikea ones) fit underneath. Makes loading / unloading things and keeping organized on longer holidays much easier.
And if you want a 'portapotty' under a panel somewhere under the bed, worth getting the measurements first (I have a space for such and carry the portapotty around sometimes, but not used it yet (would have been better with more forethought). Sadly, I can only use the shower outside.

Thanks guys I put the floor through the lashing points but I might double up with the bed as well. Great idea using the holes for the bumper I'll take a look

Thanks again
