Sealy Innerspring Series Firm

The Sealy Innerspring Series Firm is ideal for people who are looking for firm surface support with just the right amount of padding for body-hugging comfort. Backed by a 10-year warranty, this model is a budget-friendly option if you need a relatively firm sleeping surface for extra back support. This top-selling sleep set up is available at Mattress World Northwest in all standard sizes, whether you’re shopping for a twin, a split Queen or a California King. It’s also available in extra-long sizes for taller individuals.

Among the many standout aspects of this Sealy innerspring mattress is its exclusive gel foam layer, which regulates temperature and provides a cool sleeping surface. This comfort layer is complemented by pressure-relieving memory foam and a patented coil system that enables couples to sleep soundly through the night with minimal movement disturbance. The quality quilting cover is both soft to the touch and easy to clean.

Just what the doctor ordered.

The Sealy Innerspring Firm was heavenly to lie down on compared to my old mattress, which was way too soft for my needs. So far, this bed has given me excellent support for my lower back with no pressure points. Having suffered with terrible back pain for nearly five years, this was just what the doctor ordered, and I can’t complain about the price which was much lower than I expected for such quality craftsmanship.

I really LOVE this bed.

Don’t be fooled by the price point on this Sealy — it is a fabulous mattress if you want a slightly firmer bed that won’t break the bank. My brother-in-law has a super pricey Tempurpedic and I think my innerspring is just as good, if not better. Plus I love the gel foam — it really does sleep cooler than other beds. The customer service at Mattress World Northwest was great from the start, with no hard sells or pushy salespeople. I really LOVE this bed and am planning on picking up a twin for my son’s room as well.
