I'm looking to purchase a new king-size mattress. I'm 6ft tall and weigh between 10.5 and 11 stones, a typical tall thin cyclist build. I sleep mainly on my side, and occasionally on my back. My current old worn out mattress isn't very comfortable and I'd often get shoulder ache after a couple of hours. Hence I'm thinking a soft..ish mattress with progressive support might be the answer?

After much reading around both your websites (Factory-Beds, JohnRyanContemporary) I’m coming to the conclusion that the Hybrid 1 Laygel model may be the best option given my budget (£600 max) and weight/characteristics. I do have a couple of concerns, one being that it will be used on a bedframe with a sprung slat design, 50mm slats with 50mm gaps. However I intend to board this out with MDF as detailed in one of your articles, with some strategically drilled ventilation holes. I was also thinking of putting a topper between mattress and MDF, would a cheap mem foam topper off eBay be sufficient?

My second concern is with potential heat build-up?

Does the Laygel foam get much hotter than say one of your Pocket Sprung mattresses e.g. Origins Pocket 1500, which I was looking at but was concerned I’d find that too firm. Thanks in advance for any guidance. >
