This mattress felt amazing last night! I'm a side sleeper and woke up with absolutely no back pain for the first time this morning and it's only been one night of use! It's the perfect width for me since I'm 300lbs and hubby is 200lbs. It's important to make sure your mattress is thick enough for your weight. It's not too plush and nice and firm so your legs don't sink in during activities as well. Over all, I'm very happy with my mattress purchase! The only thing is that you can kind of feel the springs inside if you push your hand down but that's to be expected with this type of mattress! It seems durable and the lifetime warranty is great. It's a perfect fit for my space.

Could not love this mattress more! It is extremely comfortable. I have back issues and my back hasn't hurt once! Doesn't take long to set up or to reach its full size and there was literally no odor. Great quality for the price! My only complaint would be the sides are a little softer than I like but the bed is so great, I'll take that one dislike! There is no transfer of motion, can't feel my husband tossing and turning! Highly recommend!

My husband and I have been sleeping on an all foam mattress the past 10 years. It was ok, but I started having many episodes of back pain this year. I was advised to get a firmer mattress. I found this one on Amazon and was skeptical to get it due to how affordable it is and it having springs but arrives rolled up. It arrived a day earlier than promised, but we waited to unroll it until Friday morning since we weren’t sure if we could sleep on it same day. It says it needs up to 72 hours to fully expand. This mattress was a heavy beast. With my back issues, hubby had to do the majority of the work. I was disappointed that when it was unrolled, the sleeping side was facing the floor, and the top/bottom were on the sides. We had to flip and rotate this large (king), heavy mattress. But that was the worst of the experience. We unrolled it at 5 am, and by the time we went to bed around 8:30, it seemed to be expanded enough so we decided to sleep on it. WOW! Best night’s sleep in a long time! Even better the second night! It was firmer than our foam mattress ended up before we got rid of it. But it was still soft enough that you don’t feel like you’re sleeping on a hard board. It has the right amount of support. I’m normally a side sleeper, but I have been sleeping a lot more on my back too because it has such good support! Any way I sleep, this has been comfortable and supportive. I love how tall the mattress is, and it seems to be made out of good materials. Obviously I can’t speak to the durability, and we’ll see how well the springs hold up, but so far I am so happy with this purchase. If you’ve been having back pain and/or need a new mattress, I highly recommend this one. My back pain has significantly improved to where I hardly have any after 2 nights on this mattress. I am so grateful I took a chance on this one. And I like that it was assembled in the USA.

Amazing mattress! Best nights sleep I’ve have had in a long time. Perfect firmness! I would highly recommend

The bed is extremely firm, which works for me but if you are hoping for a medium firmness might be a little too firm. I like the hybrid of coils and foam and the top of the matress is nice with quilting to keep the loft in place. My one down side is one corner of the bed is not aligned properly. At first I thought I needed to let it completely fill out from the packaging, but it is still wonky as seen in the pictures. The mattress arrived faster than expected. This is a heavy mattress, so get help opening it and placing it on the frame. Overall it was a great price and I do recommend the mattress.

Very good mattress for the price we paid! Beautifully stitched mattress top. Unboxed and grew into shape quickly in one day. We were able to sleep on it that night after unwrapping it in the morning, and did not notice any odor that some reviews mentioned. Firm support that we wanted for back pain. Very happy with purchase!

It's been 2.5 months sleeping on this bed and I've never felt better. It has a firm and stable support but still soft to lie on, not a marble slab as I feared. This is my first super firm bed purchase, as I've always enjoyed sleeping on pillow mountains. With my age and deteriorating joints and muscles, switching to a hard mattress was necessary. This is the best sleep I've ever gotten at home. No hip pinched joints, all the shoulder pains I had are gone, and I'm sleeping deeper and dreaming more than ever before. The downside, is the king sized bed was an elephant to lift and to roll out. Once it expands, it's in place forever. I cannot lift it again due to how heavy it actually is. Have 2 people help you get it in place before you cut the seal and roll it out it was inflated in 30 minutes but I left it alone for 3 days before laying on it. Excellent purchase and I will use their products for my other bedrooms now.

The edges are not as strong as they claim. Don't hang your legs over the edge every night to watch TV or anything. After a while the strength of the edge wears out. It's been about 2 or 3 months with the mattress. It's bouncy, comfortable and very high. Just the edges are not holding up as good as I hoped.
