Olee Sleep 12 Inch Hybrid Queen Mattress - Gel Infused Memory Foam & Pocket Springs for Support & Pressure Relief - CertiPUR-US Certified Firm Mattress in a Box - Perfect for Back Pain Relief & Side Sleepers

***6-Month Update!*** 2/15/2017: We're on the 6-month mark and by now, I was SURE this mattress would give me something to complain about. Nope!! We are six months into using this bed and still can't be more pleased. I expected some sagging on either side from where I sleep and my husband sleeps, but it's held up very well. It is SO comfortable and we no longer wake up with back pain and aches. It's been a great purchase and I still can't recommend it enough!!**UPDATE** 10/15/16: We have had this mattress 2 months now and enough sleeping on it to give this a more updated review. I'll stand by what I wrote below and reaffirm just HOW MUCH we love this mattress. It's been extremely comfortable since day one. I no longer wake up with back and hip pain. Never expected as much comfort from such an inexpensive mattress that comes rolled and compressed to your door. We have never had any issues with smell or any sinking thus far. I will say, it was a tad more firm than I expected, even though we decided so within the first 2 weeks of getting it. We did add an inexpensive foam topper which gave us just the added cushioning we wanted with the firmer support from underneath. My point: I have zero hesitations recommending this and I would buy another one tomorrow in a heartbeat.**8/20/16: I carefully scoured the options and read through every piece of feedback on this mattress before pulling the trigger. "A mattress in a box, delivered like a sleeping bag?? AND it's supposed to be great?! Yeah right." But, (thank you Reviewers who give their honest feedback), I settled on trying this (I NEVER buy anything without checking reviews). For the price, it was worth the risk. I'll say flat out I have never bought a bed I haven't tried first. We purchased a $1300 bed 2 years ago we have hated since day 1...and despite promised "warranties", the dealer never made our misery right. So to Amazon I go and I'd rather buy something many people have unbiasedly reviewed then buying in a store where only the salesman tells me it's wonderful. It's arrived...ahead of schedule and I'm thrilled. First off, someone made a comment about it looking like the FedEx truck delivered it with a tow winch....yes, this is has been through the grinder. Thankfully my mattress inside was well wrapped. It's heavy - you'll need 2 people. Put it near the bed when you unwrap it, because within just a minute or 2, it will fully expand to its size. It puffed up instantly and filled to its shape. I am SERIOUSLY impressed that this shows NO sign of being compressed...it looks like the mattress store just delivered. After letting it puff for 4 hours, I laid on it....it is firm but giving. I cannot wait to try it tonight...and cannot wait to follow up on this in a few weeks/months. Off the bat, I can't recommend this enough. How this mattress is this price (thanks China), I have no idea. It looks and feels like one that should be much more. Last note...absolutely NO odor from mine and no feel of the bedsprings either.
