Gel-Flex Trilogy Adjustable Bed

Why We Love It

The Gel-Flex Trilogy Adjustable Bed is our most versatile pocket spring option — available in soft, medium, or firm feel so you can choose exactly the right level of support for your body. All three comfort levels share the same outstanding specification: 1500 optimum pocket springs, Gel-Flex cooling foam, and edge-to-edge support, built entirely in the UK with a full 5-year guarantee. Whether you prefer a gentle, cloud-like feel or a firmer, more supportive surface, the Trilogy has you covered.

Prices shown include our standard adjustable base. If you're looking for something more advanced, we also offer the Lifestyle and i-Motion bases — find out more about our adjustable bed bases. Upgraded bases are available to order in store — please contact us for details.

Who It's Best For

• Those who want to choose their comfort level — soft, medium, or firm feel available so you get exactly the right support for your sleep style
• Those with back, hip, or joint pain — adjustable positioning takes pressure off key areas and supports natural spinal alignment
• Anyone who sleeps hot — Gel-Flex cooling foam actively draws heat away for a cooler, more comfortable night's sleep
• Anyone who snores or has breathing difficulties — raising the head of the bed can make a significant difference
• Couples with different sleep preferences — king and super king sizes are two linked single units, each independently adjustable

Available Bases

• Standard Base (included in listed price) — twin motor mechanism, 5-part adjustable slat system, 28 sprung birch slats, chrome curved mattress support bar, solid wood construction, chrome glides, supports up to 25 stone (158kg)
• Lifestyle Base — an enhanced adjustable base with additional comfort features and refined movement control, ideal for regular daily use. Available to order in store.
