Just had a look at the Panda ones. Look interesting. Their UK small double is 135 quid and 5cm vs the Duvalay cheapest option which is 2.5cm and 150. If you got the Duvalay 5cm Equivilent then it’s 170. You can of course go the full bifta and get the upgrades that takes either option to 230.
So at it’s best, it is a 15 quid difference, at the equivalent, 35 and worst, 95. What they feel like in comparison you would have to try them both but we like our Duvalay (the 230 one) even if it is a pain in the backside to travel with.
You could argue, based on marketing spiel, that the Panda is equivalent to their Duvalay Freshtech one, which is 230, but who knows.
Personally a good nights sleep is worth what you are willing to pay for it, and I have a thing about supporting UK made products like Duvalay, vs far east mattresses in a box, so we have always been happy with our choice.
