Product Description

VAT Relief – Pay 0% VAT On Medical Use Adjustable Beds:

While electric beds are growing in popularity as luxury items with those who enjoy the finer things in life, they are also still a vital piece of equipment for many. People with long-term illness or registered disabled are exempt from paying VAT on adjustable electric beds.

Do you qualify for a VAT-free adjustable bed?

If any of the following apply to you, then you very likely do:

  • A physical affliction which has a long-term adverse effect on your abilities for carrying out everyday activities.
  • A mental impairment with long-term adverse effects on your abilities to conduct regular, everyday duties.
  • The condition you suffer from, such as diabetes for example, is treated by the medical profession as a chronic sickness.
  • Purchase of the bed is specifically for assistance with your disability.
  • You have a terminal illness.
  • Acquiring an adjustable bed is only for personal or domestic use (although someone else can still purchase it on your behalf).

If you are eligible, call our sales team today on 01928 242829 to receive a quote minus the VAT. Even if someone else is purchasing the bed on your behalf, we can still provide a quote minus VAT. Prior to purchase, you will need to complete a VAT exemption form … then the adjustable bed of your dreams will soon become a reality.

Discover ultimate comfort and tailored support with the Derwent Adjustable Bed Mattress. Featuring 1000 pocket springs and foam encapsulation for edge-to-edge reinforcement, this bed ensures optimal spinal alignment and enhanced durability. With a luxurious 2.5" Air-Lite comfort foam layer and a tufted design, it offers a plush yet supportive sleep surface, promising a rejuvenating and restful night's sleep.

Base sold separately.

Medium to Firm Tension - Good for people who change sleeping position

  • 1000 Pocket Springs - The pocket spring system is the best at providing individual support to the sleeper. The upper part of the spring shapes to the body contours while the lower part absorbs changes in weight distribution for the ultimate in comfort and support. The springs work independently to avoid roll together
  • Air-Lite Comfort Foam - Air-Lite Comfort Foam conforms to the body's contours, providing personalised support and pressure relief. This helps alleviate discomfort in sensitive areas like the hips, shoulders, and lower back, promoting better sleep posture and reducing the likelihood of waking up with aches and pains. Foam mattresses are inherently resistant to dust mites and other allergens, making them an ideal choice for individuals with allergies or asthma. The dense structure of foam inhibits the accumulation of allergens, creating a healthier sleeping environment. Air-Lite Comfort Foam is designed to maintain its shape and resilience over time, offering long-lasting support and comfort, this durability contributes to the mattress's overall lifespan, providing value for your investment.
  • Foam Encapsulated - A high density foam strip placed inside the edge of the mattress springs, prevents the mattress from sagging and gives both longer life to the mattress and a more supportive sleeping area. This also means that you have more edge to edge support on the mattress. -Tufted - The traditional method of mattress upholstery where the fillings are secured with tufts from the top of the mattress to the bottom to ensure all loose fillings are secured to provide the perfect finish.
  • Easy Care - No need to turn, but regular rotation from head to toe will extend the mattress's life span.
