Assessed from Silentnight's product page, captured September 2026, and from regular price comparison across our UK retail partners.
Choose this mattress if you sleep on your back or front and want a firm, stable surface. As a hybrid with pocket springs, each spring moves independently, which means better contouring to your shape and less motion transfer than an open coil design. If you share a bed, that matters: your partner's movements are less likely to wake you. The size range is generous, covering UK Single, Small Double, Double, King and Super King, so it works for a spare room or a main bedroom. Yes, the £910 starting price is a real spend, but firm hybrids from established brands tend to sit in this bracket.

Who's it NOT for?
If you're a lightweight side sleeper, a firm mattress may feel too unyielding at the shoulder and hip, so a medium tension would likely suit you better. It's also a stretch for tight budgets, with prices starting at £910. And if you prefer the deep sink of an all-foam bed, this sprung hybrid will feel different.
