{"product_id":"monarch-cool-gel","title":"Reign Monarch Cool Gel Mattress","description":"\u003cp\u003eMonarch Memory Cool Gel mattress is designed to combine pressure-relieving memory foam with cooling gel technology, helping reduce heat build-up while still giving that supportive “memory foam hug” feel. The key things buyers usually look for in this type of mattress are cooling performance, spinal support, motion isolation, and durability. Gel-infused foam is specifically made to sleep cooler than traditional memory foam by dispersing body heat more effectively.  \u003cbr\u003eThe 25cm Luxury Mattress works well for people who want the contouring comfort of memory foam without overheating at night. The hybrid construction also improves edge support and airflow compared with older all-foam designs. Gel foam mattresses are known for better temperature regulation and pressure relief.\u003c\/p\u003e","brand":"Reign Mattress","offers":[{"title":"3ft","offer_id":42985384640610,"sku":null,"price":139.99,"currency_code":"GBP","in_stock":true},{"title":"4ft","offer_id":42985384673378,"sku":null,"price":159.99,"currency_code":"GBP","in_stock":true},{"title":"4'6ft","offer_id":42985384706146,"sku":null,"price":159.99,"currency_code":"GBP","in_stock":true},{"title":"5ft","offer_id":42985384738914,"sku":null,"price":179.99,"currency_code":"GBP","in_stock":true},{"title":"6ft","offer_id":42985384771682,"sku":null,"price":209.99,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0678\/2736\/8034\/files\/ChatGPTImageJun2_2026_12_56_33PM.png?v=1780387112","url":"https:\/\/reignsleep.co.uk\/products\/monarch-cool-gel","provider":"Reign Mattress","version":"1.0","type":"link"}
