Easy to select the mattress I wanted; it was delivered promptly and in good condition. Its a good quality product and I would use this company again.
They attempted to deliver a mattress that was to big to go up my stairs my mistake didn't account for the fact it wouldn't bend. They took it back then advised me on the best one to have. Within 24 hrs I had a diffrent one delivered and the delivery guys took it up stairs for me no extra charges . Customer service was great

Delivery came on time, constant updates as to where you are in line for your delivery, I would certainly use again.
Next day delivery of new mattress as promised, swift & efficient service.Very comfortable, firmness level just right, went for medium firm rather than previous firm. Helping ease hip pain already after only a few days

A super king zip and link mattress is essentially a super comfy giant mattress that can transform into two single mattresses! It's made up of two individual single mattresses zipped together along the long side. This clever design offers you the ultimate flexibility, with lots of benefits too.
For more, read our guide on Should You Buy A Super King Or Two Singles? to discover why this might be the best type of mattress for you.
A zip and link super king mattress is designed to give you the space of a super king with the option to split the bed into two separate sleeping surfaces. The matching halves fasten together through the centre, helping them stay aligned when used as one bed.
A zip and link super king mattress can offer:
A full 180cm x 200cm super king sleeping surface when joined
Two 90cm x 200cm long single mattresses, when separated
Less movement travelling from one side of the bed to the other
Easier handling through doorways and staircases because the mattress comes in two parts
A flexible setup for couples, guest rooms and changing bedroom arrangements
This makes zip and link designs especially useful when you want generous sleeping space without committing to one fixed bedroom layout.
Start with how you plan to use the bed. Think about whether it will stay joined most of the time, be split regularly for guests, or need to suit two sleepers with different comfort preferences.
For an everyday main bed, compare firmness, support system, comfort fillings and mattress depth just as you would with any super king size mattress. For a guest room, ease of moving and reconfiguring the two halves may be just as important as the overall feel.
Firmness and comfort
Firmness describes how soft or supportive the mattress feels, while the comfort layers shape the cushioning and overall sleeping surface.
The current range includes different firmness levels and a choice of fillings, so you can compare options based on the feel you prefer. If two people will share the bed regularly, agree on a comfort level that works for both sleepers and check the individual product details before ordering.
Use the table below as a quick guide to how different firmness levels can feel and which sleeping preferences they may suit.
Firmness | Best suited to | Typical feel |
Lighter and side sleepers | Plush with deeper cushioning and more sink | |
Side and combination sleepers | A balanced feel with cushioning and support | |
Back and combination sleepers | More supportive with gentle cushioning | |
Front sleepers and firmer-feel fans | Stable and supportive with less sink |
Support system and construction
Zip and link super king mattresses are available with different support systems, including pocket springs and traditional open coil springs. The construction can affect how responsive, stable and cushioned the mattress feels.
Pocket springs move independently, which can help the mattress respond more closely as you change position. Open coil systems use connected springs for a more traditional feel. Compare the support system alongside firmness, fillings and depth rather than choosing on one feature alone.
The zip and link design itself adds flexibility, while the mattress construction determines the feel of each half. Check the product specification to make sure the support and comfort combination suits how you sleep.

Who is a super king zip and link mattress best for?
A zip and link super king mattress can be a practical choice for couples who want plenty of room, households with flexible guest spaces and anyone who needs a large mattress that is easier to manoeuvre in two sections.
Joined together, the two mattresses create a 180cm x 200cm super king. For separate guests, they split into two 90cm x 200cm long singles, so the same room can support different sleeping arrangements.
It can also be useful in homes with narrow staircases, landings or doorways because each half can be moved separately before being joined together in the bedroom.
The practical benefits of a split super king design
A zip and link super king mattress uses two halves that connect through the centre. Joined together, they give you super king proportions while still allowing the room to be reconfigured when needed.
This can make zip and link mattresses a useful option if you want:
More flexibility, with one super king bed that can become two long single beds
Easier handling and delivery access because the mattress comes in two separate pieces
Less movement travelling across the full bed because each sleeper rests on a separate mattress core
A more secure joined setup than simply pushing two unrelated single mattresses together
A practical way to adapt a guest room for couples or individual sleepers
Comfort depends on the mattress you choose. Compare firmness, support system, fillings and depth, then check each product for the features that matter to you. Aim for the right balance of comfort and flexibility for how the room will be used.

A zip and link mattress is made up of two separate mattresses that join together to create one larger sleeping surface. This gives you the flexibility to use them as one super king bed or separate them when needed.
As each side has its own support system, the design can also help reduce the ‘roll together’ effect that can occur on some shared mattresses. You may still notice the central join slightly, depending on the mattress and how you sleep, although securing both sides together and adding your bedding can make it less noticeable.
Couples can also pair the joined mattress with separate duvets, an approach often called the Scandinavian sleep method. This can help reduce disturbance from duvet pulling while still letting you share one super king bed.
Yes, some zip and link mattresses are available with different firmness levels on each side, which can be useful when you and your partner have different comfort needs. For example, one side could be medium while the other is firm.
Body weight can influence how firm a mattress feels, so a heavier sleeper may prefer a firmer level of support than a lighter partner. However, weight is only one factor. Your sleeping position and personal comfort preference also matter, so check the available split-tension options for the mattress you’re considering before choosing.
Because a zip and link super king mattress comes as two separate mattresses, each section can be easier to manoeuvre through narrow staircases, doorways and other tight spaces than one full-size super king mattress. Once in the bedroom, the two mattresses can simply be linked together to create the full sleeping surface.
Free next-day delivery is available on eligible in-stock mattresses across the UK mainland. Delivery times vary across the range, so check the individual product page and the delivery information shown at checkout before you order.
The price of a good mattress depends on brand, support system, comfort fillings, firmness, depth and other product details. Compare the features you will use most often and choose a mattress that gives you the right balance of comfort, flexibility and value.
