## Questions & Answers

**Q: Hi Can you feel the springs laid on this mattress please?**
A: Hi, yes it’s thin can feel all springs through it. I recommend you to buy Newentor mattress,  It is really comfortable, can improve pain and sleep, is supportive and does not collapse easily. Recommended! I hope my answer is helpful to you!

**Q: Will there be noise when sleeping on it?**
A: No. Very good, comfortable and soft to sleep on.
No noise.

**Q: Has anyone used it for a long time and how do you feel ?**
A: I thought it was good value for money until we received it and put it on my daughter’s new bed. It’s not firm at all very soft and goes down incredibly when sleeping or sitting on it. I switched to a Newentor mattress，It’s honesly the best night sleep I’ve ever had. Sooo comfy I’m buying a single one for my little girl.

**Q: Is this to fit 4ft 6 bed frame?**
A: Yes. It fits a standard UK 4 ft 6 double bed.
