### ⭐⭐⭐⭐⭐ 5.0 out of 5 stars







  
  
    Good quality
  

*by W***G on Reviewed in the United Kingdom on 16 April 2022*

This was for going into a bedroom. After reading the reviews I was worried that I had done the wrong thing by buying it.When it came it was folded and not like the picture and rolled ( no big deal still the same product)It was the correct thickness to what I ordered, yes there were a few bits of the foam harder than others but it is made of recycled foam. No problems with fitting even though it was folded. Once I put the carpet down over the top it was perfect. Comfortable under foot. I would happy use this again on the next carpet I fit.

### ⭐⭐⭐⭐⭐ 5.0 out of 5 stars







  
  
    Fantastic and easy to handle
  

*by Ó***. on Reviewed in the United Kingdom on 19 October 2022*

I chose it to add an insulation layer to my boat's cockpit ceiling. It was easy to cut (never use a cutting blade, use scissors) and glued nicely to the ceiling with spray adhesive. It works great, and the heat retention in the cockpit has improved quite a lot.I was going to cover it with vinyl, but it does actually look alright for now as is.

### ⭐⭐⭐⭐ 4.0 out of 5 stars







  
  
    Feels good
  

*by G***F on Reviewed in the United Kingdom on 2 September 2020*

The most difficult thing about this order was trying to work out exactly what it was.  The title says 8, 10, 12mm thick and the images say 8 or 10mm.  There is a bit in brackets at the end which says 8mm 4m so you have to guess that that is what you will get.From the pictures I expected it to come rolled up but it came folded in a box.  But it is nice and soft and has gone down flat.  4m has just done what I needed, which is good, as I have no idea how you would order a bit more without going for double.  The thickness appears to be about 9mm and it is easy to work and feels soft underfoot.For the price it is good quality and easy to use underlay.
