When it comes to finding the perfect sleeping arrangement, flexibility, comfort, and personal space often top the list. Whether you’re a couple with different comfort preferences, a homeowner furnishing a guest room, or a hotelier managing frequent guest turnover, zip and link mattresses offer a practical yet luxurious solution. At Somna Beds, we specialise in UK-handcrafted beds designed to enhance every aspect of your sleep, and zip and link options are among the most adaptable choices available.

This blog covers everything you need to know about zip and link mattresses, from how they work to their benefits, sizes, uses, and more.

What Are Zip and Link Mattresses?

Zip and link mattresses are designed to give users the option of either one large bed or two separate single beds, depending on how the mattresses are configured. Essentially, they consist of two single or small double mattresses that are joined together using a strong but discreet zip along the side. Once zipped, they function as a single, larger mattress — often forming a super king or emperor size bed.

The ‘link’ component usually refers to the bed bases, which are secured together using metal brackets. This ensures that the mattress remains aligned and doesn’t drift apart during the night. While they may look like a traditional one-piece bed when joined, the flexibility they offer is unmatched.

How Do Zip and Link Mattresses Work?

The concept behind zip and link mattresses is beautifully simple yet highly effective. Each mattress is manufactured with a zip on one side. When you want to create one large bed, the two mattresses are zipped together. When you need to convert them into two singles — for example, for guests who prefer sleeping apart — they can easily be unzipped and used separately.

This setup works equally well with the bed bases. The bases come in two parts and are usually linked at the base with secure clips or metal fasteners. The entire design allows for easy transition between configurations, giving you full control over the sleeping arrangement in just a few minutes.

What Sizes Are Available?

In the UK, the most common zip and link configuration is two 3ft single mattresses joined to form a 6ft super king. However, other sizes are also available, including options for small doubles or bespoke sizes depending on your space and requirements. At Somna Beds, we offer made-to-order zip and link beds tailored to the measurements and finishes you need, ensuring a perfect fit for any bedroom or hospitality setting.

What Are the Benefits of Zip and Link Mattresses?

The biggest advantage of a zip and link mattress is its versatility. For couples, they offer the chance to personalise each side of the bed. One person may prefer a firm surface while the other needs more cushioning — and with a zip and link setup, both can sleep comfortably on the same bed without compromise. Each side can be tailored to the individual's preference, including different firmness levels or materials.

Another significant benefit is practicality. If you’ve ever struggled to get a super king mattress up a narrow staircase or through a tight hallway, you’ll appreciate how much easier it is to move two single mattresses. This is especially helpful in older homes, loft conversions, or apartments with limited access.

In hospitality and guest rooms, zip and link mattresses shine as a space-saving and cost-effective solution. They allow the same room to be quickly adapted for couples or solo travellers, without needing to swap out beds or keep spare furniture in storage. This not only improves guest satisfaction but also saves valuable floor space and time.

Do Zip and Link Beds Feel Like One Mattress?

A common question many people have is whether zip and link mattresses feel like a single mattress when joined. The answer is yes — particularly when the mattresses are of high quality, like those from Somna Beds. The central zip is designed to be discreet and sits below the surface level, so you don’t feel it while sleeping. In fact, many users can’t tell the difference once the mattresses are zipped and a fitted sheet or mattress topper is placed on top.

Our beds are also built to stay aligned throughout the night, thanks to strong zips and secure link brackets on the base. You won’t find yourself falling into a gap in the middle — only enjoying the generous space and comfort of a well-made super king bed.

Who Should Consider Zip and Link Mattresses?

Zip and link beds are ideal for a variety of users. Couples who want individual comfort without separate bedrooms will find them incredibly useful. Guests with different needs can enjoy personalised sleep without conflict. Families with multi-use guest rooms benefit from a flexible setup that can host couples, friends, or even children at different times.

Hospitality businesses, including boutique hotels and bed-and-breakfasts, rely on zip and link mattresses to maximise occupancy and accommodate every guest scenario. The convenience of quick reconfiguration, along with the professional look and feel of a joined super king bed, makes them a smart choice for commercial settings as well as private homes.

Are They Easy to Maintain?

Caring for zip and link mattresses is much the same as maintaining a regular bed, but with a few added conveniences. Because each mattress is smaller and lighter, rotating them is easier, which helps to extend their lifespan. Should one side begin to show signs of wear before the other, it’s also possible to replace a single mattress instead of the entire set — a practical and cost-effective solution in the long term.

At Somna Beds, we offer guidance on proper mattress care, along with recommendations for protectors and toppers that can help keep your bed in excellent condition for years.
