# How to Join Zip-and-Link Mattresses

> Zip-and-link systems join two matching mattresses — often two Singles into a Super King — with a zip or linking strip. Place both on a flat joined base, align the zip edges, close the zip fully, then add any bridge cover or topper. Dual spring tensions stay separate. Do not force a zip past fabric catches.

Structural components: two matching mattresses, zip or link hardware, optional bridge cover or topper, paired or split base.

## Steps

1. Assemble and level the [base](/beds/assemble-a-divan-bed) first.  
2. Place mattress one, then mattress two, zip edges together.  
3. Match head ends (labels or pillow tags the same way).  
4. Close the zip or fit link clips.  
5. Add a bridge cover or continuous topper if you want less centre feel.  
6. Fit sheets sized for the **joined** footprint (often Super King).

## Tips

- Different [spring tensions](/mattresses/spring-tension-vs-comfort-feel) can sit
  side by side — that is a main reason to use zip-and-link.  
- Do not drag zips across grit; vacuum the edges first.  
- For definitions see [zip-and-link](/glossary/zip-and-link) and
  [couples guide](/mattresses/couples-and-zip-and-link).

## Frequently asked questions

### How do I zip two mattresses together?

Lay both mattresses on the finished base with zip edges touching. Start the zip at the head or foot as the maker marks. Close it fully along the length. Smooth any fabric fold before you force the slider.

### Do I need a special base for zip-and-link?

You need a base the full joined width, often two linked halves. Dual adjustable bases need a split surface. See couples and zip-and-link for why people choose different tensions.
