I was looking for a good mattress for a long time at a reasonable price and finally found one at Sigma Mattress in Agawam with Vladimir. The mattress was made quickly and with great quality, and they also provided home delivery, which was very convenient. I am very happy with both the service and the quality of the mattress. I highly recommend it! 🥰🥰🥰❤️❤️❤️
View on GoogleMy sigma mattress is amazing!! We bought a second one within a year! And we made a huge mistake - we moved to England for what we thought would be two years. And we didn’t bring the mattresses. And now we’ve been here for over 3 years. Whenever we talk about whether to move back, that mattress finds its way into the conversation.
View on GoogleNeeded a custom size mattress for my antique bed. Placed the order yesterday and got the mattress delivered to me today! I live less than an hour drive from them but still, getting a custom made mattress so quickly is rather impressive. Furthermore, the mattress fits perfectly and there's no extra charges for adjustment such as cutting the mattress corners so that it can be fitted into a 4 poster canopy bed. Excellent service by Vladimir and his team and couldn't be happier with this company.
View on GoogleSo happy that I decided to go with Sigma Mattress for my new bed. The quality is like no other, my mattress is comfortable and was also affordable! The customer service was off the charts! Vlad was very easy to communicate with during the process of me ordering and receiving my mattress! Would highly recommend Sigma to anyone looking to upgrade their sleep!
View on GoogleCan’t recommend them enough. Ordered custom made organic latex mattress from them 6 months ago. The staff were a pleasure to work. The mattress comfort is just perfect, I can finally wake up without my back aching, build quality is excellent all around, and it cost me a fraction of what other retailers quoted me.
