Unique Points

Four layer, customisable hybrid construction:

  • 4cm foam
  • 5 customisable comfort zones with 4 different densities of deep foam
  • 10cm individual pocket springs (coil count: 1,000)
  • The springs are encapsulated in a high density, supportive foam that makes up the base and the mattress walls. They're then covered in a medium density reflex foam that ensures you feel the bounce of the springs below.

Note: This brand has changed hands so many times, it's hard know the current quality of the mattress.

The Eve Lighter uses only two foam layers to give you gentle cushioning and medium-firm support with extra pressure relief:

  • Evecomfort® foam
  • Supportive base foam layer.

Construction & Materials

Tweak
Eve Lighter
Layers
foam, customisable comfort zones with 4 different densities of deep foam, individual pocket springs
evecomfort® foam, supportive base foam layer.
Cover
Hypo-allergenic, plush fabric cover. Our visco-elastic polyester blend cover provides a breathable sleeping surface. It's fire resistant and provides temperature control, plus it's hypo-allergenic making it ideal for those with dust or skin allergies. The zippable cover can be machine washed at 30 degrees and air dried, keeping your mattress fresher for longer.
Top cover (98% polyester and 2% elastane). The moisture-wicking material of this top panel stops you getting hot and clammy - a bit like sticking one leg out from underneath the cover. To keep it extra hygienic, the top panel can be unzipped and popped in the wash at 40 degrees.

Comfort
The Tweak mattress (formerly known as the Nrem mattress) is designed to help all sufferers of chronic pain, including back pain. You can design your very own sleep experience by adjusting the foam tablets inside the mattress to give bespoke comfort and support to suit your specific pain needs. Pressure relieving, cooling comfort layer. This 4cm deep comfort layer contours and cushions the body for a greater level of comfort. The open cell structure wicks away moisture and keeps you cooler for longer.
We take your comfort very seriously, so the top layer of this mattress provides your body with a velvety cushioning. To keep your spine aligned, we use our special, springier evecomfort® foam. So, the only thing you'll sink into is a night of deep sleep. This is the same evecomfort® foam that eve use in the eve original mattress. The evecomfort® layer is 30 times more breathable than traditional memory foam.
Support
5 customisable comfort zones with 4 different densities of deep foam. We use highly resilient Polyurethane foam in super soft, soft, medium and firm densities so you can get comfort and support in all the right places. This foam bounces back quicker than standard memory foam so you can turn over without feeling stuck. Our 5 comfort zones can be changed at any time so you can get your best night's sleep. 1,000 individual pocket springs for superior support and bounce. 1,000 full size pocket springs make up the mattress core. They're individually wrapped and move independently as you sleep, so you won't be disturbed by your partner's tossing and turning during the night. Our springs measure 10cm high and have a gauge of 1.5mm. As the springs are encapsulated in highly resilient base foam you get edge-to-edge support.
To wake brighter, your mattress needs to give your body enough support. The bottom layer has this in bucket loads thanks to the thickness and density of the foam. We've even added small cutouts to give your shoulders some lovely pressure relief. Get your support from a thicker, stronger base foam. And, because we want you to wake feeling your best, we've added tiny cutouts to ease the pressure from your body. This firmer base foam helps spine alignment and 'zoning' relieves pressure from your shoulders.
