    • Slowly sinks body
Style: Level Four Medium Size: Queen
Looks good in person but, terrible mattress sinks with body slowly. I’m 168lb person. No support, no comfort. Still waiting for refund it’s been over 2 weeks returned. It shows on their side in their system RECEIVED. On my account, I SEE it says, RETURN REQUESTED WAITING TO RECEIVED ITEM..LIKE WHAT?? Customer service talked to several agents of Amazon. My payment plan payment is DUE tomorrow. AGENTS keeps saying it will not come out. Still shows I SEE “PAYMENT DUE” on my account. Agents said “I’m guaranteed my refund”. Update: Was told by another agent today the next payment will be taken out again until someone in where house processes the return. Then it may take up to 30 days for both payments to be refunded. WTH?? BEWARE OF RETURN PROCESS OF THIS MATTRESS! ... show more

    • Half the price of the Black
Style: Level Four Medium Size: King
Brought this bed instead of the Black. Its simply amazing. And half the price of the Beautyrest Black. Most comfortable bed we’ve ever owned! Its definitely worth the buy if your budget won’t allow a Beautyrest Black. Compare the specs between the two. Never slept better.

    • Comfy mattress, but sags quickly
Style: Level Four Medium Size: King
I purchased this mattress to replace a cheap memory foam mattress. It was a major upgrade and I felt it was a bit of a splurge to buy this model. I slept so well on in the first few nights! Although it is still a comfy mattress, I am a bit disappointed in the wear it is showing at only about a year old. There are noticeable divots in the mattress where I sleep and where my husband sleeps. For the price point, I had hoped I wouldn’t notice sagging so quickly. We’ll likely have to replace it MUCH sooner than expected. It’s comfortable, but for the lack of longevity it shouldn’t be priced so high. ... show more

    • Valley effect
Style: Level Four Medium Size: Queen
Im not sure about this, I returned it do to that "Valley" effect in the middle.... So idk maybe it was just the one I got.. The one in the store wasn't like that at all. I sent it back within my time frame and bought a NECTAR PREMIERE from AMAZON that I am completely happy with.

    • Very well made bed, comfortable.
Style: Level Four Medium Size: Queen
I was really excited about this Beauty Rest bed, having experienced them in a hotel stay once. When it arrived, it was in a box (a rather large one) and required two people getting it upstairs into the bedroom. Once removed and onto the box spring, you are met with this stunning ribbed and well made mattress. It is not too firm and feels really comfortable to lay on. It doesn't shift around due to the weight and has incredible cooling on it. Even in our 100-degree weather where we live, it is not hot at all laying on this. I also like that it is a very thick mattress and offers a lot of support to my back. I move a lot when I sleep, but the best part, it doesn't move at all and my spouse is able to remain asleep as well. No smell at all when it was removed from the plastic wrap. Again, feels really good to sleep on and I feel my back and bones really adjusting well to this mattress. We have had it for about a week now and are really enjoying it. ... show more

    • Finally sleeping through the night
Style: Level Four Medium Size: King
This mattress hit the sweet spot for me — not too firm, not too soft. I usually toss and turn, but the support and pressure relief have made a real difference. The coils keep movement isolated, so if my partner shifts around, I don’t feel it on my side. The top has that cool-to-the-touch feel, and it really does stay cooler through the night, which is a big deal since I tend to overheat. It feels substantial and well made, not like some of the compressed-in-a-box mattresses I’ve tried before. I wake up without the usual sore shoulders, and I’m actually sleeping longer stretches without waking up. Easily one of the best upgrades we’ve made to the bedroom. ... show more
