Buy the mattress

Buy the bed! If you're hesitant and worried about buying online without testing it… I assure you it's worth it. I have had the worst luck with mattresses the past few years. I e been buying on Wayfair and they are NOT cheap… always disappointed but unwilling to return and ship back for a refund because how do you even begin to do that once it's out of the box… so I've suffered. I've NEEDED a mattress… I've had the worst back pain and serious lack of sleep. I figured for the price of this even if I hate it it couldn't be any worse than what I had. I've been on it for a week now and I'm excited to go to bed. It contours to your body BUT is also firm. It's the perfect mattress. Will it hold up over time? I can't be sure. It seems like a good quality mattress but only time will tell. If it only lasts a year or two? I've already got my moneys worth at that point.

For a great rest.

whether you're tall or short you still have to climb into the bed literally, I suggest having a bed covering that is not so smooth to lay on so that way you don't slide off the mattress when laying on it. other than that it feels like your sleeping on top of the mountain, just make sure you look out for your landing.

Hello Character! Thank you for your honest and detailed review. We’re glad to hear the mattress is exactly as advertised—firm, true to size, and free of unpleasant odors. It’s wonderful that pairing it with a pillow topper made for such a blissful sleep experience. We also appreciate you sharing the tip about being careful when unboxing, as the mattress does inflate quickly once opened. Thank you for your recommendation, and we’re thrilled you’re happy with your purchase.
