1 – A no turn mattress is not a benefit, but a requirement of the Memory foam construction method. The Memory foam, softer material, sits on top of Reflex foam, firm supportive material, and this makes the mattress one sided. To turn it would damage the mattress. Don’t be duped into thinking this saves you time. Our range all come with dual construction fully turn-able toppers to extend the life of your mattress.
2 -Memory foam and other foams will all compress at some point as they ‘bed in’. It is not always a bad thing providing its minimal and consistent. The cheaper the material the quicker and more prominent the compression. Minimal compression is known as bedding in. A compression that is over the accepted 2cm amount is known as dipping where the bed has failed you. You should always be looking at 5cm plus for your Memory foam layer so that the compression is minimal. The thinner the layer the more prominent the compression, so a 2cm Memory foam layer that compresses by 2cm will fail to have any purpose!
3 – There’s a huge branding exercise around the material your bed is covered in from infrared to anti dust mite which has little impact on your sleep, the money they cost is best spent elsewhere. A removable fire retardant polyester cover is fine for a Memory foam or Latex mattress since it will be covered by your fitted sheets. You can always take this off and wash it as part of your maintenance routine. You are better off spending your money on decent set of cotton fitted sheets and duvet covers instead where you will feel the benefit.
4 – We recommend that you rotate a non turn mattress monthly if possible to reduce compression. All of our dual construction mattresses come with fully turnable toppers that can be rotated and turned to extend your mattress life. All mattresses should be turned, flipped and rotated where possible. Failing to do so may result in dips, lumps or reduced longevity for your mattress!
5 – A Solid Core Latex Mattress is the King of Latex mattresses and can be turned and rotated. This is why they command a higher price but are ultimately much more durable. Make sure you ask if your Latex mattress is solid core, most are not. All of our Latex Mattresses are solid core Latex!

Hi,
I am looking for a mattress for my son’s bunk bed the dimensions are 80 x 190 (depth 15-16cm). Do you have any products that might be suitable?
Thanks
Hi Jenny, I’m afraid we don’t sell such a shallow depth of mattress. This is because our range are all incredibly deep to provide you with the highest quality mattress that will last. I understand bunk beds cause height issues with really high mattresses my advice would be to maybe look at Ikea whose range is good quality for money for this purpose. Hope that helps – Lee

I’m interested to know if you could manufacture me a bespoke mattress based on the specifications of a well known mattress I want but think is over priced. Is this something you at John Ryan can do through your bespoke mattress section? Mark
Hi Mark, The simple answer is no. I would never simply copy or replicate another mattress. Decent companies spend considerable time designing and testing them. I also wouldn’t take their specifications as gospel, my mattresses have all been made to our bespoke designs at John Ryan Contemporary that we have tried and tested. We are old fashioned that we would never take someone else work as I’m sure you will understand. Lee
