Purchased for my 88 year old mother. She’s 120 pounds wet. Being a smaller person most beds are just too firm and always needed a memory foam topper. The topper would always shift making it very difficult for her to make the bed. The Sunset Luxe is one of the softest beds on the market. She’s a back sleeper and there’s no working the mattress in. It’s perfect right out of the box. It’s being used with an adjustable base and the mattress responds beautifully. Edge support could be a bit better but that’s the only complaint I have. I’m in Canada, shipping plus exchange rate does make this one of the pricier mattresses but using Sleepopolis ratings for Helix allowed me to choose the perfect mattress.
