Product Description

The Gemini Eco Mattress from Silentnight features their exclusive Mirapocket Spring System which helps to distribute your weight evenly across the entire mattress and provide ultimate comfort and support. The fillings within this mattress are hypo-allergenic, making the Gemini Eco an ideal choice for those who suffer from allergies or asthma.

Medium to Firm Tension - Good for people who change sleeping position

  • Mirapocket 1200 Spring System - Each mattress with Mirapocket technology contains individual small springs, which are housed in their own separate fabric pockets. Each spring helps to spread your weight evenly across the bed providing the perfect, firm support and comfort that's second to none. It offers zonal support for perfect spinal alignment. This system eliminates roll-together so less partner disturbance.
  • Eco Comfort Fibres™ - Silentnight's intelligently designed Eco Comfort Fibres™ are made from recycled materials and are fully recyclable, reducing both waste to landfill and marine pollution. Durable and breathable, Eco Comfort Fibres™ allow air to pass through the mattress, transferring heat and moisture away from the body for a refreshing and invigorating night's sleep, ideal for those who get hot during the night. These high-performance eco-friendly fibres are free from chemicals and foam for a safer and healthier sleep environment.
  • Zoned Support - Enjoy head-to-toe zonal support to provide total spinal and body support. The mattress is firmer in areas where greater support is needed, such as the lumber region and softer in other areas, surrounding the hips and shoulders.
  • Hand-Tufted - The traditional method of mattress upholstery where the fillings are secured by hand with tufts from the top of the mattress to the bottom to ensure all loose fillings are secured to provide the perfect finish.
  • Soft Knit Fabric Cover - Upholstered in a soft to the touch fabric to create a luxurious and smooth sleeping surface.
  • Chemical Free Fire Retardancy Cover - Flame retardant cover without the use of any chemical treatments, providing a fresh and clean sleeping environment.
  • 100% Recyclable - This mattress is 100% recyclable at the end of its life.
  • Quilted Border - A more contemporary method of securing the mattress fillings, where the side comfort layers are quilted together providing a smoother looking border edge.
  • Flag-stitched Handles - Handles on both sides for ease of positioning.
  • Air Vents - Vents to allow good air circulation, regulate temperature and keep the mattress fresh.
  • Mattress Cover Material - 100% Polyester.
  • Double Sided Regular Turn Mattress - Turn over and rotate your mattress once a week for the first 3 months and then once a month thereafter to help the fillings settle evenly.

Great service from Land of beds. The mattress is superb and of real quality for the price. It is firm yet soft and has given us both a much better nights sleep. Only problem is it makes it harder to get out of bed in the morning!

Can’t recommend this mattress highly enough; for the price it’s excellent and provides good support and comfort all round. I swapped my memory foam Ikea mattress for this and the difference has been fantastic; no aching hips and neck in the morning. Land of Beds are superb too, staff were professional throughout. Thank you.
