The Tranquil Gel Spring Mattress is the cooling-focused model within the Essentials range, combining breathable spring support with a gel comfort layer to help regulate temperature and enhance overall sleep comfort. It's a practical option for anyone upgrading from a basic spring mattress who also wants to address a warm-sleeping problem. The gel-infused comfort layer is designed to dissipate excess heat and help maintain a cooler sleeping surface while evenly distributing body weight to reduce pressure on joints. Beneath it, an open coil Bonnell spring system provides consistent full-body support, and a stabilising base pad adds durability and long-term shape retention. Polyester comfort fillings offer supportive cushioning and insulation for consistent comfort night after night. As with other gel-topped open coil mattresses in the range, temperature regulation is the standout feature: heat is drawn away from the body by the gel layer and then dispersed through the breathable fibre layers and open spring structure beneath, rather than building up as it would on an all-foam surface. Pressure relief and motion isolation sit at a medium and low-to-medium level respectively, in line with the open coil construction, giving a moderate, gently supportive feel rather than a deep contouring one. This makes the mattress well suited to sleepers who want a fresher surface temperature but don't necessarily need the higher motion isolation of a pocket sprung or hybrid model.

Part of the Essentials range, this mattress offers a medium comfort level via its open coil spring with cooling gel comfort layer construction, suits back, side and combination sleepers, and supports a maximum weight of 120kg per sleeper. It is delivered vacuum rolled and boxed and is compliant with UK BS7177 Medium Hazard. The mattress is suitable for slatted bases, divans, and ottomans, and only needs rotating head-to-toe every 3 months, with no flipping required. Allow 24–48 hours for full expansion after unpacking, and note that the vacuum-rolled delivery format makes it much easier to move through tight staircases and narrow hallways than a conventional flat mattress.
