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

We bought one of these 2 years ago to replace a cheaper mattress purchased through Amazon. This mattress is far more comfortable. Recently, our older daughter wanted to change to a day bed and needed a new mattress. Since it has held up well, we purchased another one.

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!!!
