Serta 10" King Medium Gel Memory Foam Mattress – Cooling Comfort & Pressure Relief

The mattress arrived on time, box undamaged. Mattress was easy to remove from vacuum sealed bag and expanded to full size right away (received in afternoon) was able to sleep on it that night. This mattress has a little give but not soft. Firm but comfortable and it really is a cooling mattress. no uncomfortable warm spots, no sagging. I love the square corners and straight edges, makes the bed look so neat and crisp, Would recommend this mattress to all.

After several nights sleeping on an air mattress with a slow leak in it, my husband and I took the jump and bought this mattress yesterday. My husband said it was heavy, but he was able to carry it up 3 flights of stairs by himself. Instructions say to allow for up to 72 hours for full expansion, but you can sleep on it before then. I was so pleasantly surprised to find that just after a couple hours, it was expanded enough to sleep on and even more surprised when I woke up this morning having had one of the best nights sleep I've had in ages! I have lower lumbar issues and i woke up without a screaming low back. im so happy with this purchase and I definitely recommend it!!!
