It slept extremely cool and I loved that. I couldn't sleep on my side because it was too firm and it hurt my hips. And i need something that conforms to my body shape to support it and I didn't feel like I got that from this mattress. It wasn't uncomfortable but also wasn't comfortable and i couldn't get to sleep in it. I have since returned it but the customer service was amazing.

I ended up having to return my king size Purple, sadly. First, the positive: customer service was excellent, and the mattress was cool and innovative and I could see how it would be awesome for perhaps someone younger and more fit/slim than myself or my husband. Night one with the mattress was good, we both felt appropriately supported, etc. But by day four or five, my husband - who is a big guy at 6'4" and a muscular 250 lbs - was sinking right through the entire mattress and sitting on the box spring when he got in bed to read at night. We did a Princess and the Pea test and I slipped my finger between the mattress and the box spring while he was sitting on the mattress..he could clearly feel it. Needless to say, sinking through to the box spring was not an ideal situation for him, so we had to return the mattress. The return process was easy, if a bit long. I've noticed a LOT of people have questions regarding the return process so I will detail it here: we contacted Purple by phone to tell them about our issues with the mattress and request a return. A few suggestions were made regarding ways in which we could mitigate the problem, but none of them would have fixed the primary issue, so Purple told us that we would receive an email with instruction for returning the mattress. The email came immediately and contained four options for returning the mattress (basically boiled down to find/contact a charity to which to donate the mattress oneself or have Purple do it for you). We chose to have Purple find a local charity which would accept the mattress. They found one in a few days' time, which was great, but unfortunately the charity could not retrieve the mattress for three weeks. We waited, the charity came and took the mattress and left us a receipt, which we emailed to Purple, and our full refund came within a few days. All in all, an easy transaction and Purple lived up to their promises, which we really appreciate. TLDR; I feel like the SmartComfort Grid is super cool, and has enormous potential, but that the mattress would benefit from having more HD memory foam or latex underneath the polymer layer. We tried it out, it didn't work for us, we returned it for a full refund. I'll keep an eye on this company and if they come out with a mattress with a deeper/more dense support layer underneath the grid, we might even try it again.

If you have back pain, lower back pain, do not get medium or soft ones. I noticed this issue more and more actually after the 100 days, I have the 3" one, it's comfortable when you lay on it, but when I wake up next morning, my lower back hurts. I wish I could try the 2" one, maybe it will help, but since it's already after 100 days, they can't make it happen.

After almost ten years with the same mattress, my back couldn't take it anymore. We decided to try Purple, and I think it's the best purchase I've made in years. The first morning after sleeping on it my pain was pretty much non-existant! My husband and I have taken to watching TV in bed now because it's so comfortable, and it's silly, but I look forward to going to sleep. I sleep on my stomach, and my husband sleeps on his side, and both of us agree it's the most comfortable mattress we've ever had. The only thing that I would say to prepare for is that the full size needs queen size sheets because of the height of the mattress. I'd definitely purchase again!

The original purple mattress was not comfortable for us. We are average height and weight but our older joints need softer support. Shoulder and hip joints felt pressure and we tossed and turned. Excellent return policy. No hassle and we were glad to have been able to try the Purple, but we needed a softer surface.

I suffer from mild insomnia and am constantly tired and exhausted for the most part of everyday. I was hoping through the purchase of this mattress that it could alleviate some my my stress, however, I in fact do get more quality sleep for when I do, but the length of my sleep hasn't changed. Overall satisfied with this product, just don't foolhardily think it'll fix all your sleep problems.

I had really high expectations for this mattress as I live in Florida so I was excited to try out the improved air flow. I found the airflow was an improvement however the mattress is so firm I am having extreme back pain from sleeping on this mattress. My figure is relatively small (5 4' & 110lbs) it seems like I don't have enough weight laying down to push the mattress down resulting in an extremely hard bed and am very sore in the morning.

We are still trying to decide if we want to keep this mattress, it is comfortable, especially on your back, but when I roll over, or sit on the edge, the depth isn't great, I can feel the platform frame underneath me. It would be perfect if it was 2-4 thicker...

LOVE Purple Mattress! I just purchased my 4th one so now there's one in each room for my kids, myself and guests. Can't say enough how much it has saved my back. I always had back pain prior to getting purple regardless of what kind of mattress I bought. Couldn't be happier.

I have a queen hybrid 4 with adjustable base and this is the only thing that has helped my back, neck and shoulder pain. I was on the verge of scheduling surgery due to the intensity of the pain. There is an adjustment period of a few days-weeks and it is absolutely worth it!!
