After struggling for many months trying to find a mattress that is comfortable and doesn’t develop a huge dip/not faulty I am relieved to say that Panda finally seems to be the one! Comfortable and so far 4 weeks in has remained sturdy and as flat as a snooker table. A rarity these days when the quality of mattresses in general seems to have gone to pot. If you’re struggling to find a good mattress please give Panda a try - it’s a no lose situation with the free trial.
