Thanks for the offer Neb but am in Wellington. Brainstorming and weighing up all options first. I agree that some extra reinforcing could be needed, sewing is not an option as the rubber edges would chip off and the clingy latex won’t allow a needle through. Am thinking a wide strip of Elastoplast or sticky bandage after the initial bond.The bond wouldn’t have much stress as it would be almost at the end or top of the bed and the cover will help keep it all pressed together.

Am also concerned about any toxicity since most of Bunnings adhesives have ominous warnings on them and so was looking more for water rather than solvent based.

It needs to be flexible rather than dry stiff. Thought of vulcanised type adhesives or something used on vehicles. What about tile adhesive...that appears rubbery but is it toxic.

Rang Para Rubber, they use spray-on Ados for the other cheap type of foam. They don’t work with Latex.

Had visitors so didn’t have time to track down a mattress person, but thinking about them, they would be more likely to lay various weight foams over top of springs and encase it all rather than glue them together.

Had this brainwave to get rid of the guest double bed and have a king single to make more room. Gave it away already. Never imagined the double topper I was cutting down was shorter. Only reason I have the extra strip to add on is because I had cut down a queen size to fit the double as they weren’t available that size. Ha, and I thought this was going to be simple.

Anything water-based won't have much of a hope of holding something like this together, and in terms of solvent-based stuff you only get fumes until the solvent evaporates and/or the glue cures, so it pretty much sorts itself out.

If you want a flexible glue you could try styrene butadiene rubber glues, of which the only non-industrial source I know is B7000, a.k.a. Chinese cellphone glue. SBR is a synthetic rubber and will glue all sorts of stuff that standard glues can't deal with.

However at some point you're going to run into the law of diminishing returns, if it's just for a guest bed then it may just be easier to get a replacement topper of the correct size off Trademe, or skip the topper entirely.

Like others my first thought is liberal spray contact. Anything else will be a nightmare to spread.

I'd be inclined to make a quick jig to mate both smooth sides under some even pressure for good contact. Topper on a smooth floor against a wall with a chair and 4x2 to keep a small amount of pressure on the mating surfaces or something like that. Newspaper underneath to avoid tack on the floor. Possibly overkill. If you have spare material to experiment with first then you'll get an idea of what might be needed if anything.

The glue gun idea sounds like it would leave a hard residue. I'd avoid that for a mattress.

Bed is against a wall so the topper makes it very easy to make by tucking sheet under it and not the deep mattress, thus the effort. Pure Latex toppers are quite expensive and I prefer them over memory foam etc as you can use an electric blanket over them.

If solvent based isn’t harmful after it dries then would go with it if stronger.

Looked up the styrene glues and they appear to be sold in bulk. Will venture out tomorrow and check out a few stores. I find most websites never show enough detail of the full specs of products.

Thanks for all the input.

Yeah, that's the problem with that stuff, it's usually only used commercially/industrially, however if you buy it as B7000 on Aliexpress or, if you're in a hurry, Trademe, you can get it for a few dollars a tube (more on TM). The downside is that there's lots of stuff sold as B7000 on Ali/TM that may not all be the same. So if you're not in a hurry get the cheapest tube you can find on Aliexpress and test a bit of that before sinking a lot of money into it.

If you can track down some Konishi Bond プラスチックthat's definitely SBR, Daiso shops used to sell it but they haven't had any for some time now.

Tracked down all of the suggestions, thanks. Trade Me had the B7000 as well as The Market. Tiny amounts though,100 ml being the most.

You don't know what a mattress topper is?

Of course - we have a mattress topper and it's some sort of thick quilting covered in soft fabric.

Great. Now imagine that but made out of latex! 😆
