Choose from Different Types of Mattresses
Different mattress types offer different feels and levels of support. Understanding the main options can help you select a mattress that suits your comfort preferences, sleeping position and bed base.
Memory Foam Mattresses
Memory foam mattresses are designed to respond to body weight and movement, creating a cushioning feel. They can be a popular choice for sleepers who enjoy a more conforming mattress that moulds around the body.
Memory foam mattresses are available in different depths and specifications. Check the individual product information for details about the foam construction, firmness, cover and care instructions.
Pocket Sprung Mattresses
Pocket sprung mattresses contain individual springs housed in separate fabric pockets. Because the springs work independently, pocket sprung designs can provide responsive support across the sleeping surface.
Our pocket sprung mattresses are available in a variety of sizes and specifications. When comparing models, consider the spring count, mattress depth, fillings and firmness information supplied for each product.
Open Spring and Bonnell Spring Mattresses
Open spring and Bonnell spring mattresses use an interconnected spring system to provide traditional mattress support. These mattresses can be a practical option for guest bedrooms, children's beds and everyday sleeping arrangements.
Open spring mattresses are available in several UK sizes, making it easier to find an option to match your existing bed or divan base. Always confirm the dimensions before ordering.
Orthopaedic Mattresses
Orthopaedic mattresses are generally designed with support and firmness in mind. They may be suitable for sleepers who prefer a firmer sleeping surface, although comfort is personal and a firmer mattress is not automatically suitable for everyone.
When choosing an orthopaedic mattress, review the manufacturer's specifications, firmness description, construction and recommended use. Avoid assuming that a mattress will treat or cure a medical condition.
Gel and Cooling Mattresses
Gel mattresses and mattresses featuring gel-infused foam may be designed to offer a different feel from standard memory foam. Depending on the construction, gel materials may also be included as part of the manufacturer's approach to temperature management.
Read the product description carefully to understand whether the mattress contains gel foam, gel panels or another cooling material. Features and performance can vary between individual models.
Hand-Tufted Mattresses
Hand-tufted mattresses feature tufts that help secure the internal fillings and materials in place. This traditional mattress finish can contribute to the mattress's appearance and construction.
Hand-tufted mattresses are available in a range of styles and sizes. Check whether the mattress is single-sided or double-sided and follow the manufacturer's instructions for rotating or turning it.
Zip and Link Mattresses – Flexible Sleeping Solutions
Zip-and-link mattresses are designed to join together using a zip system. Depending on the size and product specification, two mattresses can be connected to create one larger sleeping surface or separated for use as individual mattresses.
Zip-and-link mattresses can be useful in bedrooms where flexibility is important, such as guest rooms, holiday accommodation or rooms that need to accommodate different sleeping arrangements.

Benefits of Zip and Link Mattresses
- Can provide flexible sleeping arrangements.
- Can be separated when required, depending on the product design.
- May be easier to handle than one large mattress.
- Can be useful for guest bedrooms and rooms with changing requirements.
- Available in different sizes and mattress specifications.
Before ordering, check the complete product dimensions, zip position, mattress depth and whether the mattress is supplied as a pair or as an individual unit.
Common Zip and Link Mattress Sizes
Zip-and-link mattresses are commonly available in configurations designed to create larger sleeping sizes, such as king size or super king size. The exact dimensions can vary, so always check the product listing and confirm that the mattresses are compatible with your bed base.
Mattress Sizes Available at Bedz4u
Choosing the correct mattress size is essential. The mattress should fit the bed frame or divan base correctly, with the dimensions matching the sleeping area. Bedz4u offers mattresses in a selection of popular UK sizes.
Single Mattresses
Single mattresses are commonly used for children's bedrooms, teenagers' rooms, guest rooms and individual sleepers. They are suitable for standard UK single bed frames and divan bases, subject to checking the exact dimensions.
Small Double Mattresses
Small double mattresses are designed for beds that are narrower than a standard double. They can be useful where bedroom space is limited while providing more sleeping room than a single bed.
Double Mattresses
Double mattresses are one of the most popular UK mattress sizes and are commonly used in main bedrooms, guest rooms and larger bedrooms. Check the dimensions of your existing bed before ordering a replacement.
King Size Mattresses
King size mattresses offer a larger sleeping surface and are often chosen for main bedrooms where additional space is available. Make sure your bed frame or divan base is designed for a standard UK king size mattress.
Super King Mattresses
Super king mattresses provide an even wider sleeping surface and can be suitable for larger bedrooms. Due to their size and weight, check access through doorways, staircases and other areas before arranging delivery.
Small Single and Toddler Mattresses
Small single and toddler mattresses are designed for specific bed sizes. These mattresses must be selected carefully because even a small difference in dimensions can prevent the mattress from fitting correctly.
For children's and toddler beds, always check the manufacturer's recommended mattress size and ensure that the mattress is suitable for the specific bed design.
How to Choose the Right Mattress
There is no single mattress that suits every sleeper. The right choice depends on your preferred comfort, sleeping position, available space, bed base and budget. Consider the following points before ordering.
Choose the Correct Mattress Size
Measure your existing bed frame or divan base and compare the measurements with the mattress dimensions shown on the product page. Do not rely solely on the general size name, as dimensions can vary between mattress types and manufacturers.
Consider Your Preferred Firmness
Mattresses are available in different firmness levels, from softer and more cushioning designs to firmer options. Your preferred firmness may depend on your sleeping position, body weight and personal comfort preferences.
Always read the individual product description for the manufacturer's firmness guidance rather than assuming that every mattress in a particular category feels the same.
Compare Spring and Foam Mattress Types
Spring mattresses and foam mattresses provide different sleeping experiences. Spring systems may offer a more responsive feel, while memory foam can provide a more cushioning and conforming sensation.
If you are unsure, compare the construction, materials, mattress depth, firmness and care instructions for several products before making your decision.
Think About Your Sleeping Position
Your usual sleeping position may influence the type of mattress you find comfortable. Side sleepers often consider cushioning and pressure distribution, while back and front sleepers may prefer a different balance of support and firmness.
Personal preference is important, so use sleeping-position guidance as a starting point rather than a guarantee of comfort.
Check the Mattress Depth
Mattress depth can affect the overall height of your bed and may be particularly important if you use a bed frame with side rails, a storage bed or a mattress topper. Check the product dimensions before ordering.
Make Sure the Mattress Fits Your Bed Base
Check that the mattress is suitable for your bed frame, divan base, slatted base or other sleeping surface. Some bed bases may have specific mattress requirements, so consult the bed manufacturer's instructions where necessary.
Frequently Asked Questions About Mattresses
What Type of Mattress Is Best for Back Support?
The most suitable mattress depends on individual comfort preferences, sleeping position and personal requirements. Some people prefer a firmer mattress, while others find a medium or more cushioning design more comfortable. A mattress should not be selected as a substitute for professional medical advice.
What Is the Difference Between Memory Foam and Pocket Sprung Mattresses?
Memory foam mattresses use foam that responds to body weight and movement, often creating a cushioning, conforming feel. Pocket sprung mattresses contain individual springs in fabric pockets, which can provide a more responsive feel. Some mattresses combine springs and foam to offer features of both constructions.
How Often Should a Mattress Be Replaced?
Mattress lifespan varies depending on the materials, construction, usage and care. Signs that a mattress may need replacing include visible sagging, damage, loss of comfort or changes in support. Follow the manufacturer's care and replacement guidance where available.
What Mattress Size Do I Need?
The mattress size you need should match the internal sleeping area of your bed frame or the dimensions of your divan base. Measure carefully and compare the measurements shown on the mattress product page before ordering.
Are Bedz4u Mattresses Suitable for All Bed Frames?
Not every mattress is suitable for every bed frame. Check the mattress dimensions, depth and any manufacturer's requirements before ordering. If you are unsure, compare the mattress specifications with the details of your bed base.
Do Mattresses Require Turning or Rotating?
Care instructions vary between mattresses. Some mattresses may need rotating regularly, while others are designed to be used on one side only. Always follow the care instructions supplied with your mattress and check whether it is single-sided or double-sided.
