Discover personalised comfort and cooling technology with the Adjust-A-Bed Gel-Flex Trilogy Mattress, an advanced, supportive sleep solution specifically designed to complement adjustable beds. Offering a choice of three comfort levels: soft, medium or firm. This versatile mattress allows you to select the perfect tension for your body and sleeping style, delivering a tailored sleep experience every night.

At the core of the Gel-Flex Trilogy is an Optimum 1500 pocket spring unit, engineered to provide precise, responsive support. Each spring works independently to respond to your body’s unique shape and weight distribution, ensuring proper spinal alignment and reducing pressure points, whether lying flat or adjusting your position on an electric bed base.

The spring unit is foam encapsulated, which not only secures the spring system in place but also reinforces edge-to-edge support. This design allows you to enjoy the full surface of the mattress without experiencing sagging or a roll-off feeling at the edges—ideal for those who need extra stability when getting in and out of bed.

The standout feature of this mattress is the Gel-Flex cooling foam, which is available in soft, medium or firm densities. This advanced foam is designed to provide plush comfort while regulating temperature and dispersing body heat, making it especially beneficial for those who tend to overheat during the night. The gel-infused layer offers contouring support that moulds to your body and springs back into shape effortlessly.

A micro-quilted, knitted top panel enhances the mattress’s breathability while delivering a smooth, cool-to-the-touch sleeping surface. The 11-inch depth adds to the overall comfort and support, making it a substantial and durable option for everyday use.

The Gel-Flex Trilogy is particularly well-suited to adjustable beds, adapting seamlessly to positional changes. This makes it ideal for users seeking relief from backache, arthritis, or those simply wishing to enjoy the elevated comfort and health benefits of sleeping on an adjustable base.

Key Features:

  • 1500 Pocket Springs: Independent springs offer zoned support and reduce motion transfer.

  • Foam Encapsulated: Provides robust edge-to-edge support and stability.

  • Gel-Flex Cooling Foam: Available in soft, medium or firm to suit your personal comfort preference while offering temperature regulation.

  • Knitted Micro-Quilted Cover: Enhances airflow and provides a soft, breathable sleeping surface.

  • 11” Mattress Depth: A substantial profile that adds both comfort and durability.

  • Adjustable Bed Compatible: Designed to work perfectly with adjustable bases, enhancing positional support and comfort.

What are the benefits of an adjustable bed?

Are adjustable beds good for back pain?
