Adjustable Bed Mattresses

Discover comfort and support with an adjustable mattress, designed to work seamlessly with electric and profiling bed bases. Unlike conventional mattresses, adjustable mattresses are created to adapt to your individual sleep needs. This flexibility can help improve comfort for those experiencing back pain or circulation issues, or for anyone who prefers a more supportive, adjustable sleep position — our Mattress Buying Guide explains what to consider when choosing a mattress for use on an adjustable base.

Our range includes adjustable mattresses from trusted UK and Irish manufacturers such as Mi-Bed, Adjust-A-Bed and Respa, offering tailored support across a variety of comfort levels. Designed to move smoothly with adjustable bed mechanisms, these mattresses help promote better sleep quality and long-term wellbeing through personalised support and pressure relief.

Went with my folks who were after a Riser Recliner and an Adjustable Bed - Great selection and had a number in-stock for delivery immediately. They settled on a 'Mi-Bed' and a Sherborne triple motor Recliner and got a great price. Have been back since myself and got a Respa Mattress and Ottoman. Hidden Gem!

Having spoken to Kathryn on the phone we met her in person yesterday. She is extremely knowledgeable about beds and remained with us during our visit providing assistance and advice. I would highly recommend Dalzells as a company to do business with.

Have bought both King Koil and Kaymed Beds and Mattresses over the years from Sharon and team. Always a great price, in-stock and with free delivery. Grandfather also bought a Lift & Rise Recliner and an Adjustable Bed. Again super advice and service.

I have a bad back and needed a Sherborne riser recliner. I travelled from Meath to Dalzell's and met the wonderful Catherine. She was so helpful and patient as I tried the different types of chair. I made two or three visits to the shop and finally purchased. Catherine was so helpful in every way and inspired trust and confidence.

Travelled from Dublin to view mattresses rather than purchase online. I was met by Kathryn who engaged with us immediately and discussed options and showed us comprehensive range .She advised us on specific options that might suit out needs. We were very satisfied with her level of expertise and she explained delivery and gave a very good deal . Very professional and we went away very happy with the way our requirements were dealt with and would recommend this business to anyone. We certainly will return in the future

I emailed yesterday evening with a query regarding their stock of King Koil beds.A lady called Jathryn replied at 9 am this morning with the information I had asked for and invited me to view their selection. This i have just done. Kathryn was knowledgeable and interested in the product and we found just what we were looking for. As a result we made a purchase.
