## Questions & Answers

**Q: How do I clean my mattress?**
A: We always recommend using a mattress protector. You should not use detergents or chemical cleaners on your mattress as this may damage the fabric and stitching. Please do not remove the cover to clean the mattress, the cover is not removable.

**Q: How often should I turn my mattress?**
A: We recommend that during the first six months your mattress should be turned every two weeks and then monthly thereafter. You should alternate between turning the mattress over and rotating it from top-to-tail to ensure even settlement.

### ⭐⭐⭐⭐⭐ Very comfortable medium firm mattress, great nights sleep
*by L***I on 7 January 2026*

A new mattress was well overdue and have not been disappointed. Sleeping very well with this one. It is a deep heavy mattress but very well built, would recommend. Great support when sleeping

### ⭐⭐⭐⭐ One year on: Silentnight 2800 Pocket Eco Comfort
*by R***L on 3 January 2025*

I'm reviewing this mattress after one year of ownership. The mattress is great quality and after 1 year is still firm, with no indentations or dips where we sleep, and no roll towards the centre. The edges are also still firm, with no roll. The king mattress is extremely heavy, which two fit gym goers struggled to get up the stairs and even to turn from time to time. We have it on a base of straight wooden slats (no flex), and the mattress feels more firm than medium-firm. Because of that, it has changed how I sleep, it makes my hips ache if I sleep all night as I used to on my side and I have become more of a front sleeper now. To be fair, in this new sleeping position, I find the mattress very comfortable and get a good night's sleep. The mattress is very quiet, no noise from springs as you or your partner move. We find it far hotter than our old mattress, and no longer require an extra blanket at night in the winter. Price-wise, aim for sub-£500 in the sales (around Christmas). All in all, a very comfortable mattress that is wearing well, but it runs hot and is extremely heavy to lift.
