Review: Worth buying - This is so comfy for my little human . It thick and not hard.
Review: A perfect choice! - A wonderful high-quality mattress! Having recently bought a new king size bed with sprung slats I needed a good strong mattress, but one that was also comfortable. I went by all the good reviews and ordered this (it was the best one I looked at). It arrived today - a day earlier than scheduled - and is on the bed and great! The delivery-guy was very pleasant and chirpy - I do wish I had asked if he could have taken it upstairs for me though as we really struggled. The delivery-guy had brought it to my door on his shoulder!! I cannot wait to get in to bed tonight - but have already laid on it ;) This was a bargain price! The morning after - Seriously the best nights sleep I have had in years. I laid there reading my book for 30 minutes or so before drifting off, and it really felt like I was floating. This is a firm mattress, but extremely comfortable and so supportive. My whole body was equally supported and it really felt like I was floating. I never expected this with a firm mattress. There were no points of my body that felt unsupported - incredible! I am so glad I did my research and went for this mattress - it does pay to read up! For the first time in years I have woken up without any aches and pains. My husband is going to be so happy when he gets back from his business trip and climbs in to this. He suffers with his back. I cannot believe the price of this mattress - buy one, you won't be disappointed!

## Questions & Answers

**Q: Will my mattress smell?**
A: It’s quite normal for new mattresses to have a slight odour when they are unpackaged, however, it is nothing to worry about and by airing the mattress you will find that any odours will pass.

**Q: Is settlement normal?**
A: Your new mattress is zoned to complement the human body and it is the underlying support system that ensures you are offered optimum support in the zoned areas. Some settlement in the filling layers is perfectly normal, there is no need for concern.

**Q: Can I clean my mattress?**
A: We always recommend using a mattress protector which you wash on a regular basis along with your sheets. Using detergents or chemical cleaners on your mattress may damage the fabric and stitching. Your mattress cover is not suitable for washing.

**Q: Which sleep accessories are best suited to this mattress?**
A: The Silentnight Deep Sleep Pillow, Duvet and Mattress Protector complements the mattress perfectly, offering great comfort for a snuggly night’s sleep.

### ⭐⭐⭐⭐ Comfy and Definitely Firm
*by T***Y on 24 May 2025*

I was looking specifically for a firm and supportive mattress, and this definitely delivers. It’s very comfortable, especially if you prefer a firm or even extra firm feel—unlike many others that claim to be firm but still feel a bit soft. Great value for the price as well. The only downside was delivery. I ordered 3 items (1 King and 2 Doubles), and they arrived separately with delays, which was a bit inconvenient. But overall, really happy with the product itself.
