They’re available in a range of reflex foam and pocket spring interiors, with premium layers such as natural fillings, body-moulding memory foam and cooling gel for a fresh night’s sleep. Adjustable bed mattresses are designed to flex with the mechanism’s movement for the optimum support and comfort.

The Ultimate Guide to Large Single Adjustable Bed Mattresses

When it comes to getting a good night's sleep, the right mattress can make all the difference, especially if you have an adjustable bed. Large single adjustable bed mattresses are specifically designed to offer both comfort and versatility, making them an excellent choice for many sleepers.

In this guide, we'll explore the dimensions of a large single adjustable bed mattress, the features that set them apart, the types of mattresses available, and how to care for your new mattress. Plus, we'll explain VAT exemption and why Archers Sleepcentre is the best place to purchase your mattress.

Size Comparison: Large Single Adjustable Bed Mattress vs Other Sizes

Understanding mattress sizes is crucial when selecting the right mattress for your bed base. Here’s how a large single adjustable bed mattress compares to other standard sizes:

  • Standard Single: Measuring 90cm x 190cm (3' x 6'3"), this size is ideal for children or smaller adults but may not provide enough space for those who prefer more room.
  • Large Single: At 100cm x 200cm (3'3" x 6'6"), this size offers additional width and length compared to a standard single, providing more comfort for taller or larger individuals.
  • Large Single Adjustable: Typically, a large single adjustable bed mattress also measures 100cm x 200cm but is specially designed to bend and flex with an adjustable bed base.
  • Small Double: Measuring 120cm x 190cm (4' x 6'3"), a small double provides more width than a single but is more compact than a standard double, making it a good option for smaller rooms or those who need a bit more space than a single offers.
  • Standard Double: With dimensions of 135cm x 190cm (4'6" x 6'3"), this size offers more space but is not suitable for adjustable single bed bases.

Features of a Large Single Adjustable Bed Mattress

Large single adjustable bed mattresses come with unique features tailored to work with adjustable bed bases. These features ensure you get the most out of your adjustable bed.

  • Flexibility: These mattresses are designed to bend and move with the adjustable bed frame without damaging the mattress or compromising comfort.
  • Enhanced Support: They provide consistent support across various sleeping positions, ensuring proper alignment and comfort.
  • Durability: Constructed with high-quality materials that can withstand regular movement and adjustment.

Important Note: Electric beds must be used with an adjustable mattress that is designed to bend and flex. Using a standard mattress will void any warrantees and can lead to damage of both the base and mattress.

Types of Adjustable Bed Mattresses

There are several types of adjustable bed mattresses to choose from, each offering unique benefits to cater to different preferences and needs.

Pocket Sprung Mattresses: These mattresses contain individual pocket springs housed in their own pockets, allowing each spring to move independently. This design offers excellent support and contouring to the body's shape, making it ideal for various sleeping positions.

Reflex Foam Mattresses: Made from high-density foam, these mattresses provide firm support and pressure relief. They are lightweight, hypoallergenic, and good for those needing a firmer sleeping surface.

Additional Mattress Options

Beyond the basic types, there are additional mattress options that enhance comfort and support.

Latex Mattresses: Natural latex mattresses are durable, hypoallergenic, and offer excellent support and comfort. They conform to the body while providing a cooler sleep surface compared to memory foam.

Natural Fillings: Mattresses with natural fillings such as wool, cotton, silk and cashmere offer breathability, moisture-wicking properties, and a luxurious feel. They are ideal for those seeking an eco-friendly option.

Memory Foam Mattresses: These mattresses contour to the body's shape, providing excellent pressure relief and support. Memory foam is particularly beneficial for those with joint pain or back issues.

Cooling Gel Mattresses: Containing a gel infused foam layer, these mattresses help regulate temperature, making them perfect for hot sleepers who need a cooler sleep environment.

Pillowtop Mattresses: Featuring an additional layer of padding on top, pillowtop mattresses offer extra comfort and cushioning, ideal for those who prefer a plush sleeping surface.

VAT Exemption on Adjustable Mattresses

In the UK, certain medical and mobility aids, including adjustable bed mattresses, may qualify for VAT exemption. This can make these essential items more affordable. To be eligible, the mattress must be purchased by or for someone with a chronic illness or disability. When purchasing, customers should provide a declaration of their condition to the retailer, who will then apply the VAT relief.

If you have any questions regarding VAT exemption, please call us on 0141 892 0308 and one of our staff will be able to talk you through the process and answer any questions you may have.

How to Care for Your New Mattress

Proper care ensures the longevity and comfort of your new mattress. Follow these tips to keep your mattress in top condition:

  • Regular Rotation: Rotate your mattress regularly to ensure even wear and extend its lifespan. Double sides mattresses should also be flipped regularly.
  • Use a Mattress Protector: Protect your mattress from spills, stains, and dust mites with a quality mattress protector.
  • Cleaning: Follow the manufacturer’s cleaning instructions. Vacuuming the surface periodically can help keep it fresh and free of allergens.
