Best Sleep Ever

We got a new mattress and after much deliberation, went with a Serta. We have no more back or hip pain when we wake up in the morning, it has great support, and I haven’t slept this great in years. Another thing that impressed me was the attention to aesthetics; the embroidered flowers on the mattress top are lovely. Thank you Serta!

Great support and breathability

[This review was collected as part of a promotion.] This is an absolutely comfortable bed. Didn't know how our old bed was wore out until we felt the support this bed provides. We seem to sleep cool and it breathes well. Great packaging and should last a long time.

Best sleep I’ve had in a long time!

[This review was collected as part of a promotion.] This mattress is amazing! I didn’t know how badly I needed a new mattress until I received this one. I had the best nights sleep ever, I woke up feeling refreshed and ready to go for my day! The mattress itself is so comfortable and has just the right amount of firmness. I also like the quilted material of the mattress and the height of it. It is definitely worth the price and I am so happy to have it.

Truly the Perfect Sleeper!

Perfect amount of firmness and comfort; definitely helped with healing my total hip replacement.
