Bedroom by Spring King�

Spring King is a UK mattress specialist focusing on pocket-sprung and pocket-sprung-hybrid constructions across single, double, king and super-king sizes. The brand operates as a value-tier alternative to the established names (Silentnight, Sealy, Sleepeezee), with most pocket-spring counts running 1,000 to 2,000 and price points sitting £100 to £300 below comparable big-brand specs.

The catalogue is mattress-only. The Spring King Silver, Pure Latex, and Memory Plus ranges cover the standard pocket-sprung-with-foam-comfort-layer construction. The Cool Touch and Phase Change lines bring temperature-regulating layers for warmer sleepers. Most ranges ship roll-packed, which sidesteps the narrow-stair-turn delivery problem traditional flat-packed mattresses face.

The price band runs £130 to £1,400, with the volume sellers in the £200 to £600 king-size bracket. Most carry a 5-year guarantee on the springs and comfort layer.
