2.1m Diameter Lay-Z-Spa Pool Hot Tub Floor Protector Matt Accessory

Does the job

If you have a round inflatable hot tub then I would definitely recommend this. Fits my palm springs perfectly and seems to lose less heat than without.

Perfect to protect the bottom of you Lazy Spa Pool, providing extra padding, insulation and reduces noise if you have your Lazy Spa and pump on a hard patio floor or timber decking.

Used for a year and does the job as intended

Although a bit fiddly to put together, once it's done then it looks good and stays together with the weight of the hot tub on it. Will be a great protection for underneath because previously the bottoms of our tubs have been filthy. Can't comment accurately on insulation because we also have an insulation cover, but the combination of them both makes a massive difference, only losing 5 degrees in 24 hours in Autumn (34 down to 29) which means keeping it warm will save a lot of electricity.
