Mattress Topper
Color: Green Bamboo(2300gsm), Size: Queen
So far I haven’t really got to get a feel of it. I will say it came smelling very strongly. I’ve had it now for 3 days & it still has a smell. I let it sit out for 24 hours, with the window opened but it still has an odd scent & once I put it on my bed it’s still smelling strong. It’s kind of hard to focus on my comfort when the smell is very odd & foul but aside from that. The reviews are on point in regards to its softness.

This is beyond awesome!
Color: Green Bamboo(2300gsm), Size: Queen
I have Airbnb properties and I have bought all sorts of bed toppers. Nothing that I have ever bought has been THIS perfect! Anything with polyester is going to fail you. This one is exactly what I was hoping for which is ONLY shredded memory foam that will last and give you what you want for a cloud like experience!! I just got delivery of this one and unpacked it! It is above and beyond anything I could hope for! It is 100% shredded memory foam through and through, very nice and thick!!
It's extremely well made and well packaged. I am totally thrilled with this bed topper! No more experimenting with my purchases anymore.. and sending them back when it's nothing like. I hope. This one is EVERYTHING! YOU HAVE GOT TO GET THIS AND YOU WON'T BE SORRY!
