Mysore Silk Plus Coir Mattress

I bought the Mattress just two weeks before the lockdown started. And I have waited about two months before giving a review so that I understand the complete picture.

1) Comfort 9/10. I have had no problems related to backpain or side pain while sleeping. Way above average over regular mattress.

2) cooling effect 9.5/10.
Almost as advertised. Usually mattress gets hot at night , this doesn't. I dont sweat as much in powercuts as earlier. So thats a big plus.

3) functionality and appearance: 8/10.
I understand its a gel foam mattress but when you sit on it, its a little too much sink to my liking. Maybe in future if they can tweak the support layer to reduce it, that would be superb. I mean, we all do sit and work sometimes on bed right?
But looks wise, white and clean. Nice texture also. Bedsheets hold on to it superbly. No sliding.
