I bought two of these for a new pull out trundle day bed. Quite smelly but I’m lead to believe that’s normal for memory foam. It’s 5 days later and the smell is still quite strong so I’m glad I bought two fully enclosed mattress protectors to go with them. Delivery was bang on time and the bag made them easy to carry upstairs. When you open the bag they pop out and start to expand nicely. Ideally you would air them for a whole week before using, I reckon, as the smell is pretty grim. We had guests for the weekend who said they were very comfortable. I had a quick lie down and agree - they’re good and supportive without being too hard, plus you can’t feel any hard bits inside, in the way you sometimes can with other mattresses. I obviously haven’t had them long, so I can’t say how they will fair long term, but they’re in the spare room so won’t get a lot of use anyway. I really hope the smell goes away…

As I did not use it, I cannot comment on any thing but the feedback I received from my guests are positive.By feeling, I can say it is a good, well made and comfortable mattress.

Very happy with this mattress. Had same one before. It lasted about 5 years before it showed signs of dips, but chose to buy the same type again as very comfortable. It would be useful to have handles to help move it around as it should be turned around every 4-6 weeks. Last time I sewed some to the cover myself.

So far can't fault the mattress, we left it to stand for 24hrs, then after that it was puffed up ready to go. Very comfortable, good night's sleep. How long it will last time will tell. Looking at it from its build quality, I'm optimistic it will last.

Very pleased with this mattress - not too soft. Interestingly enough it feels 'better' when used with a bedframe (I've just moved house and for the first few nights mattress was just on the floor). Definitely recommended.

Good To Know

Frequently asked questions

Is the Stellar 1000 suitable for allergy sufferers?
Yes, the Stellar 1000 is recommended for allergy sufferers due to its specific fillings and fabric, making it a suitable choice for those with sensitivities.
Can you describe the mattress cover?
This mattress comes with a knitted cover designed to stretch as the mattress moulds, providing significant elasticity and breathability for enhanced comfort.
How does the memory foam in the Stellar 1000 benefit sleep?
The memory foam provides body moulding and pressure relief, ensuring that it contours to your shape while always recovering to its original state for ultimate comfort.
What is the benefit of the micro quilted finish?
The micro quilted finish is created by stitching together the fabric and fillings, resulting in a patterned comfort quilt layer that enhances the overall feel of the mattress.
Do I need to turn the Stellar 1000 mattress regularly?

What kind of sleep positions does the Stellar 1000 accommodate?
The Stellar 1000 is designed with a firm tension, making it particularly suitable for front and back sleepers.

This layer is specifically designed to work in harmony with the 1000 pocket springs and memory foam layers above, ensuring that the mattress maintains its supportive structure while also offering a cosy sleeping surface. By combining this eco-friendly foam with the other materials, it helps to create a balanced sleep experience that supports a range of sleeping positions.
How long does it take for the mattress to fully expand after unpacking?
After unpacking the mattress, it usually takes between 4 to 24 hours to fully expand and reach its proper shape and size.
What is the fire safety rating of the Stellar 1000?
The mattress has a Domestic Flammability Rated Source 2, indicating it is considered low hazard for general domestic use.
