The Harmony Spring Mattress is the entry point to the Aurora range, offering dependable open-coil support with a slightly firmer, more traditional sleep feel – ideal for everyday use in any bedroom, and a good match for sleepers who find softer mattresses lacking in structure. A durable Bonnell spring system delivers even, full-surface support with a firmer, more traditional feel, while a denser support layer adds structure and helps the mattress hold its shape for longer. The breathable quilted cover improves airflow and moisture regulation, and inner polyester layers add cushioning without softening the firmer base too much. Because the Bonnell spring unit is interconnected rather than individually pocketed, movement on one side of the mattress does transfer more noticeably to the other, and motion isolation is correspondingly low – something worth bearing in mind for couples, though less of a concern for single sleepers or those sharing with a still sleeper. Pressure relief sits at a moderate, medium level, and the overall bounce is best described as steady and traditional rather than plush. This straightforward construction is also what keeps the mattress accessible in price while still delivering the firmer, structured feel that many back and stomach sleepers specifically look for.

Part of the Aurora range, this mattress offers a medium, firmer feel comfort level via its open coil bonnell spring 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 take advantage of the rolled, boxed delivery format when moving it through tight staircases or narrow hallways.
