Siegvoll Foam Cup Holder (Without Cup) for Motorhomes, Caravans, Boats – storage for 8 cups
Product description
What it is (and why you’d buy it)
This Siegvoll foam cup holder is designed for one job: holding cups, mugs and glasses securely in a cupboard while you’re travelling. It’s made as a foam organiser (PU foam) rather than a rigid rack, which is the key idea here. Foam can cushion impacts and reduce the rattling you often get when dinnerware shifts around on the move.
You get a holder without cups included, so you’re essentially buying the storage insert. The product is aimed at travellers who want their motorhome/van/caravan/boat cupboard to stay tidy and, more importantly, to keep porcelain and glass items from bumping into each other during driving and movement.
Key features at a glance
The holder is sized to fit into a cupboard space, and it’s built with multiple compartments so you can store eight cups/mugs/glasses in a single unit. The layout is split by cup diameter: four spaces for cups in the 6 to 7 cm range and another four for cups in the 7 to 8 cm range. That split matters, because if your mugs are consistently outside those ranges, the fit will be awkward and you may lose the cushioning effect.

Material-wise, it’s PU foam described as safe, non-toxic and harmless. The intention is clear: it’s meant to protect cups rather than just to “store” them.
One thing to note up front: it’s not described as dishwasher-safe. Foam organisers like this typically shouldn’t be treated as something you can rinse and run through a dishwasher, so if cleanliness is your main concern, you’ll want to plan for manual cleaning.
Where it shines in real use
On paper, the best benefit is noise and impact control. In practice, that means you can load your cups into their slots, close the cupboard, and worry less about porcelain chiming or glass surfaces rubbing together. If you’ve ever had mugs clatter during travel, this approach is aimed directly at that problem.
A practical example: imagine you’re heading out for a weekend trip. You set up the kettle, use your mugs at the table, then pack them back into the motorhome cupboard. With a foam insert like this, each mug sits in its own position and is less likely to slide around when the vehicle tilts, especially compared with loosely stacked cups.



Because it’s foam, it should also take minor irregularities in cup shape better than a fixed plastic grid. That said, it’s still only as good as the cup sizes you’re trying to fit.
What to watch before buying
Before you even think about whether it’s “worth it”, measure first. The product instructions explicitly say to measure your motorhome cupboard and your cups, then estimate using the product dimensions so everything fits.
Two more limitations are worth putting in your decision:
- Not suitable for drawers. If your storage plan is a drawer rather than a cupboard shelf, you may be fighting the wrong format.
- Dishwasher not suitable. It’s not intended for dishwasher use, so you should be comfortable cleaning it by hand.

The dimensions given are 33.5 x 25 x 6 cm (L x W x H) for the holder. That height matters because you’re working with cupboard clearance: if the space above or below is tight, you may not be able to fit it properly.
Also, because it’s specifically laid out for 8 cups with two diameter bands, you should check that your existing set isn’t all the same size but outside the 6–8 cm range.
Who it’s for (and who should skip it)
It makes the most sense if you’re regularly travelling with multiple mugs or small glasses and you want a simple way to stop them knocking together inside a cabinet. This is the kind of travel accessory that suits people who like keeping things organised, rather than improvising with towels or loose stacking.
It may not suit you if:



- your cups are outside the 6–7 cm / 7–8 cm diameter bands
- you’re trying to use it in a drawer
- you need a storage solution you can easily maintain via dishwasher cleaning
In other words, it’s a practical protective insert for cupboard storage, not a universal storage solution for every mug size and cupboard type.
What to compare it with (decision context)
In this category, the alternatives tend to be either rigid rack organisers or softer protective solutions. Rigid organisers can be quick to load, but they often don’t cushion as well and may still allow cups to rattle if the fit isn’t tight. Foam inserts like this are the more protective approach, especially when you’re focused on preventing bumps and noise.
The trade-off is maintenance and fit sensitivity: foam storage works best when your cups match the intended size ranges and when you can place it neatly within your cupboard dimensions.

Buying verdict
Is it worth it?
Worth considering if you’ve got a cupboard space that matches the holder’s 33.5 x 25 x 6 cm footprint, and your cups fall into the 6–7 cm and 7–8 cm diameter bands. The foam concept is aimed at quieter, safer travel storage, particularly for motorhomes, caravans and boats.
You may want to skip it if you planned to use it in a drawer, if your cup sizes don’t align with the diameter slots, or if you need dishwasher-friendly storage materials. If you prioritise easy, universal fit over protection and noise reduction, this one could feel a bit restrictive.
