Hyder Black (Hyder Beds) Mattresses are targeted toward the mid-range price point, often featuring a combination of high quality pocket springs in large numbers as a base support layer alongside popular comfort layers of gel and cashmere to name a few. Operating out of their factories in Dewsbury, a hub for mattress manufacturing in the UK, these guys are NBF accredited, which goes a long way in the bed world. They also produce all mattresses to British Manufacturing Standards. The beauty of Hyder Black Mattresses offer is simple, the price point means these are probably one of the more reasonable choices when you consider the quality of the components. Pocket springs don’t come cheap, neither are any of the comfort layers available in this range considered “cheap” and if you were to go to a bricks and mortar retail store looking for this spec of mattress you would typically be paying around 30-40% more for the privilege, more to throw a brand name behind it. Reviews for the Hyder Black range are currently a bit unknown, the brand does not appear to have been around long and seems to currently be sold primarily through Mattress Next Day although the suppliers website does welcome trade accounts and so you may find deals elsewhere online in due course. While I cannot talk to the longevity of the mattresses based on historic reviews, I can talk about the longevity based on the specifications, all of which are very impressive, for example, normally in a mattress at these sort of price points you would expect around 1000 springs, in these they appear to range from 2000-4000 and don’t mistake spring count for firmness, rather, springcount helps with body contouring, ensuring the right amount of pressure is applied in the right places to ensure adequate posture and back support.
