The Sealy Nostromo 1400 Pocket Latex Mattress, also known as the Teramo 1400, uses Sealy's 1400 pocket spring system and innergetic latex to create an unparalleled sleeping experience. Providing you with all the support you need without being too firm, the Sealy Nostromo 1400 Pocket Latex Mattress is designed to deliver outstanding comfort, whether you sleep on your back, your sides, or your front. The Nostromo 1400 uses Innergetic Latex that immediately moulds to the contours of your body to support the spine. The use of Latex also stops mites and bed bugs, making it ideal for those who suffer from allergies.

Tencel cover for enhanced, pillow-top comfort

The quilted Tencel cover is designed to keep your mattress at a cool and comfortable temperature, minimising moisture by creating a ‘micro-climate’ in the bed. Added Purotex reduces the chances of mould growth, for a fresher, more hygienic sleeping environment.

No-turn means no hassle image

No-turn means no hassle

The Nostromo 1400 is a no-turn mattress, meaning you don’t have to flip-and-turn on a regular basis. All you need to do is rotate it from top to bottom once a season. The construction of the mattress means that it always provides the correct level of support, regardless of the orientation.

Which? Best Buy 2020

Which? is regarded as a benchmark for excellence, so if a product gets the coveted ‘Best Buy’ award, you know it’s good! The accolade means that it’s been independently tested for comfort, durability, value for money and longevity, and has been found to be superior to all other comparable mattresses in its class. It comes with a 5-year guarantee for complete peace of mind, and is a National Bed Federation approved product.

The firmness rating of 3 (Medium) means that this isn’t as hard as other orthopaedic mattresses, but the use of Latex makes it firm enough to provide the correct level of support all along the spine. The 1400 individual pocket springs flex and respond to the body’s pressure, allowing you to keep your spine in that all-important ‘neutral’ position to avoid stress or pressure points. The design also ensures that there’s no roll-together, so everyone gets a great night’s sleep!

Also known as the Sealy Teramo Latex 1400 and the Sealy Messina Latex 1400.


1400 Pocket Springs

Pocket springs are springs mounted in their own seperate fabric pockets, meaning they work completely independently of one another and can provide your body with better pressure relieving support.


Natural latex provides perfect comfort and support with its ability to naturally contour to your body shape.

30cm Depth

This mattress is approximately 30cm deep.

Medium Support

Good all-rounder for front, side or back sleepers.

1400 Springs

This mattress contains 1,400 individually pocketed springs (in a King Size).

Tencel Cover

The mattress cover incorporates Tencel, an innovative fibre that naturally cools you and manages moisture. Tencel also helps to combat bacterial growth and is soft and comforting.

No Need To Turn

A single-sided mattress which does not need to be turned/flipped. One-sided mattresses should, however, be rotated head to toe regularly.

Pillow Top

Pillow top mattresses have the benefit of an additional pillow layer of plush fillings on the top of the mattress, which provides extra luxurious comfort.

No Roll Together

Individual personal sleeping zones mean that you won't be disturbed if your partner rolls or moves, as you won't feel their motion. There's also no tendency to roll towards the middle of the mattress.

Turning Handles

Flag-stitched handles are attached to the sides of the mattress to assist in turning or rotating.

I bought this bed...
I bought this bed after seeing lots of positive reviews. Its good quality and comfortable. However I deducted a star because like some other reviewers I think this bed is more firm than the medium it is shown as. I'm still glad I bought it though.
