  • For the price it doesn’t get much better.
Style: 12 Inch Size: Queen
Orderd this on a whim needing a new matresses I was gonna get something far more expensive but said why not try the bed in a box option out what’s the worst that can happen Amazon takes returns. It came next day at 6am which was super fast. it Opened it allowed it 32 hours to expand prior in the guest room before placing it on the slatted bed frame. Overall this mattress is great it’s comfortable and has a little give but you don’t sink and is a solid medium firm mattress rating. Very comfortable and fills the contours of my body while not making me feel like I’m trapped or sinking into one side or the other. It has good bounce and support to it thanks to the sleeved coils I hate pure foam mattresses they offer little support and are to sinky and coils just work better for overall support and this hybrid foam / coil mattress delivers. Some creases are normal in the fabric cause well it was rolled up and vacuumed sealed but the matress top portion did expand and fill out. They say 72 hours for it to be FULLY expanded(90% in 24 hours) this is at about 32 hours and feels great. To add - if you weigh more than 230lbs this is not the mattress for you as you will find it to be to soft and sinky because well that’s the real weight rating of these budget mattresses they are great if your in the weight range of under 230 but if your a 250lb-300lb person or more your gonna find this mattress does not provide the support you need for your weight range and a common complaint of people who are this weight on budget in a box mattresses is they feel the coils. I’m 6 feet 180lb this mattresses is great for me. I tested out several mattresses in stores around me and found this to be about equivalent to mattresses in the $600 range which is still not expensive for a matress considering some cost 1-2-3 grand but this being half the cost of the fore-mentioned and being just if not more comfortable is awesome and great value. When you push in with your hand on one spot it seems very soft and not firm and at first I was a little worried I’m not a fan of super soft mattresses but when you lay down on it the weight of your body distributed between all the coils balances all of it out and you get the comfort and shaping from the memory foam on pressure points but the support and stability from the coils and together they really do blend into a solid medium firm mattresses. My last mattress was a Serta perfect sleeper medium it ran me $800 and was far softer than this for reference. I find this to be more comfortable. I haven’t been added any additional memory foam toppers like I have all my life with matresses. Also no weird smells when opened which is great I know the product is verified to be clean foam non toxic etc but I remember opening up vaccum sealed foams just 10 years ago and they smelled heavy of chemicals. This had zero smell or dust or particles flying around on opening. Overall if you don’t wanna read all that above this is a great mattress at a incredible price for the comfort it provides. If your wondering or have never ordered a bed in a box like me just do it it’s great saves you a ton of money and by no means feels cheap. This thing feels Tons better than the 600$ ikea matresses for reference. ... show more

  • Amazing Bed
Style: 12 Inch Size: Queen
This bed is AMAZING! I have bought a couple of bed in a box style beds in the past and have not been a big fan. They always took forever to get broken in so that my back and hips didn't hurt like crazy in the mornings, so that's what I was expecting with this one as well. I had already planned on being sore for a couple of weeks. That was absolutely not the case with this bed! From day 1 this has been the BEST BED IVE EVER OWNED! It is very very comfortable and provides plenty of support while still being soft enough to not hurt my body. In fact, it has taken away the aches and pains of my old bed bed and provides me with a much higher quality night of sleep. The only downside is the edges are too soft and when trying to sit on the edge I feel like I'm going to fall into the floor. This is not a problem when laying on the bed but sitting on the edge you definitely notice it. I highly recommend this bed to anyone who is looking for a great bed at a great price point. ... show more

  • Honest Review
Style: 12 Inch Size: Queen
First of, you really get a good mattress for the price. We bought a queen mattress with doubt because of its price, but after a couple of weeks not a bad choice at all. It’s soft and not firm which is what we wanted. You don’t feel the coils. Offers enough support. This is not meant for someone wanting a medium firm. Also good workmanship and wonderful story on the founder and his commitment to his staff. Overall, I give it a thumbs up for comfort and good night sleep. And you can’t beat the price. ... show more

  • Luxury quality while also budget friendly.
Style: 12 Inch Size: King
The bed is perfect for exactly what it is. It doesn't need bells and whistles or fan fare. It's a good quality mattress. It's comfortable with great support. It's sturdy, great stability and well made, it won't be coming undone any time. If you need a simply good mattress at a great cost this is what you buy. Delivery was faster than expected and unboxing/set up was very easy. Also it's such a bonus that it comes right to your door. ... show more

  • Call me Goldie Locks!!!
Style: 14 Inch Size: Queen
This mattress is so comfortable!! It's not to hard and not too soft, it's just right!! Every time I think about my bed in a box I think of Goldie Locks and The 3 Bears!!! I sleep through the night and wake up with no back pains! It arrived 1 day early. It was securely packaged and even included a box cutter to prevent damage to the bed. I wish I would have caught it on video because the unboxing was unreal. As soon as I started to cut open the plastic the bed started to expand immediately! After about an hour I had my daughter jump all over to make sure it was "activated" !!! About 4 hours later it was time to go to sleep. I have been enjoying my purchase since Day 1. *You will need to purchase deep pocket sheets to prevent the corners from turning down, which has NOTHING to do with the bed ... show more
