Delighted 23 At last found the perfect mattress I bought this mattress 6 weeks ago and have slept so well since, I just can not believe how comfortable it is! It is perfect! I would say it is a medium firm mattress, very supportive with a little give, we have it on a sprung divan base. (I weigh 9 stone and husband is 12 stone). The quality of the product is excellent and the delivery although over 2 weeks, went smoothly with good communication throughout..

JuniperPKG Very uncomfortable This is clearly a very good quality mattress. However, it is the most uncomfortable mattress I have ever slept on. It is far too firm, like sleeping on a board. It does not support you at all. We have had to return it. Be aware as the other mattresses in the range are described as medium firmness we assumed this was too but it is considerably harder than the others

Debc11 Best mattress ever! Comfortable, supportive and sleep inducing…… wonderful!

Daisychain1234 Excellent mattress I recently bought this mattress and it is very comfortable to sleep on. It is firm with a subtle bounce, not hard at all. I previously had a softer mattress, but found this one provides better support for my back, resulting in a good nights sleep. It also didn't need any airing after unpacking as it is filled with natural fillings, therefore no usual new mattress smell to deal with. Excellent quality overall. Very pleased with my purchase.

Sink into luxurious comfort with the Heritage 7000 firm mattress. Handcrafted in Yorkshire as part of an exclusive collaboration between Marks & Spencer and master craftsmen Harrison Spinks, it's traditionally made with natural and breathable fillings. The individually pocketed, high-density springs offer firm support, and mould to your body for a personalised night's sleep. A layer of Ultra HD micro springs provides weight distribution and comfortable relief from pressure points. Responsibly sourced wool from British and Yorkshire farms gives a soft and springy feel while also providing temperature regulating and antibacterial properties. This mattress is available in double, king and super king sizes. Harrison Spinks were founded in 1840 and continue to put sustainability at the heart of their business. Each mattress is glue free, foam free and FR chemical free.
