Emma

Is the Emma Sleep mattress a good investment?

The Emma Sleep mattress is an excellent choice, particularly for those who sleep on their backs. Despite being an all-foam mattress, it offers a perfect blend of comfort and support that back sleepers require. It also provides adequate support for stomach sleepers, which is quite an achievement for an all-foam mattress.

What makes the Emma Mattress unique?

The Emma Original is made with Visco Memory foam, which perfectly conforms to your body shape, providing relief to sensitive pressure points and ensuring spinal alignment. The mattress also has a high-resilience extra foam layer at the bottom that offers additional back support as you sleep.

Why does the Emma mattress feel warm?
