Rated 5 out of 5 by from So comfortable! [This review was collected as part of a promotion.] THIS BED IS SO COMFORTABLE! I didn’t know if I would love an extra firm mattress but it is the most comfortable mattress I have ever slept on. I have been sleeping on this for the last month and my back pain has improved dramatically. The mattress has handles on the sides so it is very easy to lift when tucking a fitted sheet. Highly recommend!

Rated 5 out of 5 by from I LOVE THIS BED. [This review was collected as part of a promotion.] I LOVE THIS BED. This bed is exactly what I needed. The “extra firm” was no joke. It took me a few days to get used to it but it is so comfortable. I’ve been using it for close to a month now and haven’t noticed any sagging in the mattress and I sleep in the same spot every night. Highly recommend if you want a firm and comfortable bed!

Rated 5 out of 5 by from Sleeping better! [This review was collected as part of a promotion.] I had the mattress for about a month now and I slept so much better than my last one. It was time for an upgrade and I am happy! It’s super comfortable and it gives the strong extra firm support that I need. It really stayed true to its “extra firm”. And the durability feels promising so far. And noise? Nonexistent for me. It stays quiet when moving around. The mattress stays coolers than my last one. The cooling and airflow helps keep the heat from building up, which I have noticed. I’m really happy with this mattress. Definitely recommend!

Rated 5 out of 5 by from Firmness for back issues on point [This review was collected as part of a promotion.] Queen size is great. We loved the handle easy to move around. The comfort is really good for anyone with back issues. The firmness is on point and we sleep like babies! No more waking up when the other moves around!!

Rated 5 out of 5 by from Great ! [This review was collected as part of a promotion.] The delivery process was seamless and the mattress size is just as described. After sleeping on it for only two days I can say I have way less back pain already. Not sure if that shows how bad my mattress was or how good this one is. It’s firm and does not bend or crush under any pressure amount as I can tell. Even my pup is loving the new mattress. I would say this is worth the value and maybe skip the mattress in a box trend.
