I am pleased

My shoulders no longer hurt in the morning. Much less tossing and turning and my arms are not falling asleep. I slept on a Zimus mattress at an airbnb and ordered while I was still there. That one was firm on the edges. This one is super mushy and not good for sitting on the edge of to put on shoes. But I don't hurt so I am okay with sitting in a chair for shoes.

Lacking in edge support

I had a 13 in Zinus memory foam that has served me well for about 6 years. Decided it was time for a new mattress and went with their ultra cooling 12 in (thickest available now?). I like the feel overall and the cooling of it but the edge support is non-existent. Sitting on the side you feel like you are sliding into the floor, same with sleeping if you share a bed and sleep near the edge. Will probably be returning it for these reason.

Went back to Zinus!

Hubby now sleeps cool and my joints are relieved. Owned an original Zinus many years ago and put them in the rooms of the small motel we owned. Ours got ruined in a hurricane and we went with another brand because back then we could get it faster. When that one wore out, tried a hybrid but was not for us. Went back to Zinus!

Not happy!

This morning my son set up my beautiful new fullsize bed frame and unpackaged the new mattress to allow several hours for it to plump up before I would make it up with my new bedding. I have just now gone to bed and I am afraid of sliding off the edge onto the floor! The mattress is so soft and goes as flat as a pancake when one lies down! Trying to move towards the center of the bed, leaves one struggling to roll 'uphill' to the high point in the middle. I cannot see this working for me. I am willing to give it a few nights, but honestly this is a big disappointment. I love your product but this one is not good.

The best bed I have ever slept in

I had a purple mattress for 10 years and i began having awful muscle strains and pain so heard about this bed so I bought it and it is the best bed I have ever owned. No more back pain and my husband says he no longer has his knee pain. We are learning in or middle age the importance of a good mattress and i promise if you are on the edge with this one...dont be..You will thank me for the referral.

Excellent mattress!!!

“A few days ago my mattress arrived. I still have two more days to use it (72 hours). I’m really excited to try it out — it looks great, definitely a good purchase!”

Too soft

The mattress is good quality and nice material. Unfortunately it is just too soft for us. If you like to be cradled by your bed (which to lay on is lovely but a hard time sleeping) you will love this mattress. I wish it worked out for us.

Happy with new mattress

Very happy with my new mattress. Comfortable top memory foam layer, with good firm foam support below. Mild off-gassing smell for a few days, but not that bad. Seems to be resolved now. Overall, quite pleased
