I hope I didn’t post this in the wrong place, but I thought it would be helpful to buyers. I recently replaced a very old innerspring cheapish queen with a King mattress. I was initially interested in the ease of bed in a box as I was moving and really didn’t have time to get to a store. I ended up buying one of the most expensive mattresses from Helix called the midnight lux. I bought this because many, many “review sites” said it was the best of the bed in a box mattresses. Basically it’s a hybrid inner spring with a layer of poly and memory foam on top. Initially it felt great and I was very happy. However, 2 weeks into owning it there were indentations where I would sit up at night reading! 2 weeks! It made sleeping on the area very uncomfortable and I was absolutely shocked and very angry given the cost of this and immediately requested a return. I have seen this brand mentioned on this forum, and I just wanted would-be buyers to know how low quality they are. Clearly the memory foam and / or poly is very low quality and has poor durability. On the tag it says the bed is actually Brooklyn bedding made in Arizona, so Helix isn’t even a real mattress factory despite misleading statements on their website. I would be wary of BB after this experience. Anyway, using all the information I learned from this website I bought an all Latex king from Flexus FOR LESS MONEY THAN THE HELIX. 3inch x4 pieces (soft talalay, medium dun, firm dun and x firm dun). So far it’s been great as far as support. The feeling is so very different from memory foam that I’m still getting used to it (owned less than a week). It seems to be just right. Thank you for the time, expertise and information to help me make the best informed decision for a relatively expensive purchase.
